Installing A High Flow Catted Downpipe On My Manual Toyota Supra!

👋 Time to make my new manual Toyota Supra sound awesome! In this video I show how to install a downpipe for the MK5 Toyota Supra 3.0 B58. To be honest it was super easy installing the downpipe on my Supra right in the garage! This is the new MST high flow catted downpipe. It has a 6in diameter catalytic converter for a high flow design and should be very similar to a catless downpipe. Also this high flow catted downpipe wont cause a check engine light! The V-Band hold the downpipe to the turbo and then its two bold on a bracket and the clamp on the midpipe. Unplug the two 02 sensors and with some wiggling the stock downpipe pipe comes right out. Installing the new MST downpipe was just as easy. It comes with a new gasket and reinstalls on the bracket like stock. Took a bit of wiggling to get it into the factory midpipe, but with two people installing a downpipe on the Supra B58 at home is easy! he Supra sounds much better too! Definitely a noticeable increase in sound and a few more audible pops in Sport mode! I love the new MST catted downpipe for my manual Supra! MST also makes a catless downpipe for even more sound! In this video, I'll be demonstrating how to install a high flow catted downpipe on my manual Toyota Supra. This downpipe will greatly improve the performance of your Supra, and is a must-have modification for any turbocharged engine! If you're looking to increase the power and performance of your Toyota Supra, then this downpipe is a must-have modification. We'll walk you through the installation process step-by-step, and show you just how easy it is to install! Thanks for watching!

High flow catted downpipes are excellent. I installed the Fast Intentions full catted downpipes on my Q50 making a huge difference along with supporting mods. Thanks for these informative videos.

[@BrosFOURRSpeed]

Yeah I’m excited about this one! Will be cool to see the power gained once tuned! Glad you liked the video!

[@marqueseason6360]

Is your ECU unlocked? Are you able to tune your car yet? Im considering the JB4.

[@johninnh4880]

@@marqueseason6360 It's EcuTec tuned. A JB4 works pretty well too. Jacob at AMS remote tuned my car. I was one of the first Pure Stage Two turbo upgraded cars out there. 338 fuel pump and an AMS in tank fuel pump, Nostrom injectors, etc. The list goes on LOL.. I should have added Flex Fuel but didn't. 20/20 hindsight.

[@robotbro7187]

i have this downpipe on my 2022 supra. Stock exhaust, no tune, no intake. It made an already good sounding car, even better. There's a lot more pops and crackles and you hear them all, both inside and outside. It deepened the tone of the stock exhaust, and also made it louder esp from the outside...imo the exhaust note in perfect now. Also, you do notice the difference in increased power. Accelerating from 35 mph to 70 mph is noticeably faster and smoother. Its obv not gonna be anywhere close to a tune, but even without a tune you do notice an increase in power. The downpipe wasn't cheap but def worth it

[@BrosFOURRSpeed]

For sure! I've been very happy with it. Great way to add power and sound with no emissions issues!

[@chrisginoc]

How would you compare this downpipe (made in taiwan) versus an Active Autowerks downpipe?

[@BrosFOURRSpeed]

@@chrisginoc seems really good! I’ve heard good things about AA too. But a few months now on this MST catted DP and it’s been great! Tons of Supra parts come from Taiwan. They have a big BMW support base. Great products!

[@BrosFOURRSpeed]

Thanks! Yes I plan on doing the unlock. Just want to wrap up bolt on parts and cosmetics and get some more miles on the car. Then we'll dive into tuning!

[@Digga_10]

I’d like to get this going - essentially drop shipping from multiple trusted brands from several Motorsport shops on your own website. And given the “trust” factor, conversion of sales should be higher than if selling a no-name brand…

[@julianmaza1489]

Hey man I ended up getting my manual supra! You should have tried the armytrix catless dp with a cat simulator because i havent seen any vids on it and heard it works well and has no cel and is cheaper and louder than a highflow cat. Im looking into getting one but ive been wanting to see someone run it in person. So far only heard stories from people in forums who have them. Just a suggestion but great video anyways.

[@BrosFOURRSpeed]

Oh that’s cool! My GTR had their downpipes. The 02 sensors had a small housing with just a small pinhole in them. So they could barley breath the fumes. Pretty neat design!

[@joeyn7399]

Great video. I can’t remember, are you going to be running a jb4 on this car? If so I was hoping you could do a before and after dyno now that you have upgraded your intake and downpipe.

[@BrosFOURRSpeed]

I'll be doing a full tune. Once I get the rest of my exhaust and make the car FBO, I'll do a dyno day to get a baseline. Then ship out the ECU and do all the tuning. And go back to the dyno! The dyno I'll be going to has had a few manual Supra's on them, so I know what a bone stock manual Supra should put down

[@joeyn7399]

@@BrosFOURRSpeed looking forward to seeing that video. My manual Supra only has 400 miles on it so not broken in yet, but was wondering what it makes at the wheels. Thank you.

Not really. Just nice and tight. Havent had issues in any car I've removed the 02 sensors in. They always stay tight

[@rickymaldojano9666]

No tune needed right… I’m not trying to void my warranty ? And thanks for the vid! Like always!

[@BrosFOURRSpeed]

Correct! The catted downpipe won't throw a CEL, but you'll get much better then stock flow and good sounds! Very pumped about this part

[@BlackNAVYAmericanVET]

Nice

[@BrosFOURRSpeed]

Thanks! Good bump in sound!

[@ethanchu6571]

So much space down there on the manual to reach down access the downpipe! Or is the automatic also that open?

[@BrosFOURRSpeed]

I think they are both identical. Don't think the transmissions are much different in shape. Beauty of an inline engine. Easy to work on!

[@MakeEmMiss]

Would you happen to know how this mst downpipe compares to the active autowerk catted downpipe? Trying to decide

[@BrosFOURRSpeed]

I wouldn't know that brand. However Ii still have no check engine light. Fitment is perfect too on the MST. So I only have good things to say about the MST one. They are currently in stock too! So we can have it shipped out very soon if you order it

[@chrisginoc]

Last month I visited ARK Performance who is headquartered 45 minutes away from me. I purchased and had them install their ARK DT-S full catback exhaust system. When they finished installing in their shop they said to make sure whenever I end up getting a high flow downpipe that whoever installs it makes sure to do a little soldering at the connection for precaution. Is the soldering part normal or are they just being cautious by saying that?

[@BrosFOURRSpeed]

I've never heard anyone say that? What part would they solder? I had a downpipe on my last Supra for two years and we just directly installed it. Never had an issue. I don't plan on doing that for this car. Just replace the stock one with the new one and you're good. Make sure bolts are tight and you'll be good

[@chrisginoc]

​@@BrosFOURRSpeed How would you compare this MST Downpipe (new product) to the industry standard of Active Autowerks catted downpipe? Similar price but Active has a crazy good reputation of No CEL or they send you a new downpipe type of warranty. How you liking this MST so far that you've had it installed?

[@BrosFOURRSpeed]

@@chrisginoc So far no CEL. I’m super happy with the MST DP. Fit perfect and they guarantee no CEL. Loving it!

I am also thinking to get a high-flow downpipe for my 2023 Supra, is it safe to put a downpipe and cold air intake without a tune to go with it?

[@BrosFOURRSpeed]

Yup! My car hasn't been tuned and I've had this downpipe, MST and Armaspeed intake, and AWD exhaust. Car runs perfect! Check out our site for those intakes too. Right now everything ships pretty quick! Let us know

[@butleroferic1135]

I have a 2020 launch edition Supra that is currently stock. I’m new to the game, can someone explain the difference between catted vs catless down pipe? Which one is better for power?

[@BrosFOURRSpeed]

Catless with throw a check engine light since it has no catalytic converter. You will need to tune the car. This high flow catalytic converter flows much better then stock and won't require tuning. Catless will give you a tad more power with tuning vs tuning the car with this high flow cat. Catless is also going to be louder and you'll smell more exhaust.

[@JamessssssssssSupra]

I cannot tell you how helpful this was!! I just installed my downpipe today on my 23’. I did exactly what you did here and took me like 90 minutes solo. I actually think the catback install was harder by myself! Here is a quick 6 second clip. kzbin.infoUU3xOI2NT9M?feature=share

[@user-fr7jp3jq6i]

How does this compare to the AA catted DP?

[@BrosFOURRSpeed]

I've heard good things about that brand too. But everyone who's order this from us loves it. I've been loving this one and no CEL. This one definitely does everything it needs to do! They ship fast too, so let us know if you want to order it. brosfourrspeed.com/parts-%26-merchandise/ols/products/mst-performance-6in-catted-downpipe-supra

[@amill1563]

Does the exhaust sound have a low, middle, or loud setting?

[@BrosFOURRSpeed]

It has an active valve and basically on and off. Valve closed is a bit quieter. Then valve opens in sport mode and makes a bit more noise. Sport mode also changes the engine tune and makes some pops and gurgles too

[@boyutang6990]

Are you planning to install a BOV? I think it will make it sound sooooo nice.

[@BrosFOURRSpeed]

Not too sure. The factory recirc valve holds boost well and seems to not be a weak point. Not sure if vent to atmosphere would hinder power between shifts

[@boyutang6990]

@@BrosFOURRSpeed I agree performance wise there should be no difference, it would be purely for sound lol.

[@BrosFOURRSpeed]

@@boyutang6990yeah but for a manual a vent to atmosphere design would let all the boost our between shifts. The stock recirc valve keeps the turbo spinning between shifts. So not sure it’d be worth it or not on the manual. Be cool to test it tho!

Honestly want to get one now and get rid of my Type R. Just don't like the price. It'd be nice if I got an offer on my Type R for around the price of the manual Supra. Lol

[@BrosFOURRSpeed]

Type R seem to be going for some good money! I know the new ones would be same or more then a manual Supra. Old ones are still into the 40s at least. My Supra was $62 OTD. A dealer had a Type R up for $63k sale price.

[@joescivic]

@@BrosFOURRSpeed I just need something different and smaller. I LOVE my Type R, and I've been loyal to Honda for almost 24 years, but I need a 2 door again. And I love these Supras. I'd take a 3.0 as basic as it gets and just mod it down the road.

[@BrosFOURRSpeed]

Type R is a great car for sure! You'd love a Supra! Seems like a lot of Supra owners came from cars like the Type R. Would be cool to find a base 3.0 manual for like $54k at some point

[@joescivic]

@Bros FOURR Speed I also see Supra owners coming to the Type R. Lol. I get most of their reasons for a switch, but we're all different. I don't think Honda will be going back to a coupe, or even 3 door hatch any time, and I've always been a coupe guy. I mean, I have no kids. No need for extra doors. Don't plan on kids either. I wonder if my mods will ruin the price for a trade-in. I have the full PRL mod list, but still on stock turbo, with XDi high pressure fuel pump and dyno tuned with Hondata, lowered with 18's and 265 wide tires. But i still have all my stock parts if that raises the price. 🤷‍♂️ Might just drive on to a dealership now that I'm off work and see (just to look at) if they have one. All dealers websites make me full out a form if I want info on a Supra. Lame. Lol.

[@BrokenStatues7]

Does this void warranty?

[@BrosFOURRSpeed]

Technically no. A dealer would have to prove this caused an issue. The secondary 02 sensor would be the only thing this could possibly effect. So if that sensor went out, it'd be easy to blame the aftermarket cat for that. But it doesn't effect anything else in the car.

[@alexmachado8842]

Still no CEL?

Sounds good, but once you go catless its going to be a big difference.

[@BrosFOURRSpeed]

Yeah I had catless on my last Supra. So I'm excited to see how this performs and sounds with the full exhaust. Then we'll see about going catless again

[@zoob4371]

not really, high flow cats flow really well these days. probably a ~3 hp gain with a tune going from catted to catless

[@zendy04]

Why is it so expensive, a vsrf catted dp is only 480 and theres some even less, other than the cel thing but if your going to tune it doesnt matter

[@BrosFOURRSpeed]

You answered your own question lol. This doesn't cause a CEL. Big deal for a lot of people. If I have a CEL my car cant pass inspection. Lots of people aren't ready to tune the car but want the downpipe. It's going to cost $3,500 to tune my car. Lots of people just aren't ready for that but can do a high quality catted DP and get the sound with no issues. And once tuned of course gain all the power. If you're going to get a catted downpipe that does throw a CEL, might as well just go catless.
