Custom Type R Exhaust- With Active Valve

[@LessTalkMoreDelicious]

This is def the nicest & cleanest designed Honda since the ‘00s era. I love it ✨✨

[@jamesborek8125]

I'm blown away by y'all's workmanship and attention to detail everytime.. 👍👍

[@redcivic1000]

LHT. Your craftsmanship and attention to detail is so far above. Even when put against the manufacturer. Great job and keep those updates coming.

[@LHTPerformance]

Thanks for the kind words.

[@DiegoJimenez-mp2wh]

That was amazing. Can’t wait to hear it with the updated system

[@woodardisaghost]

I think that initial valve open and close during start up is the ecu checking the valve is functioning, great work as normal guys!!

[@djaric]

yea stock car stock exhaust does this.

[@garytman007]

Best sounding exhaust i have heard yet hands down. I would buy this right now if it was available. I am still unddetermined which one i want after 6 years, this one is music to my ears. Well done!

[@LHTPerformance]

It’s for sale , I’m selling the car.

[@joshwattonS2000]

That’s properly cool, craftsmanship is second to none. Also, well done on the weight loss George. 👍🏼

[@djaric]

My old 10th gen Si exhaust sounded better than my stock type-r. haha. And I miss the little burbles the si had. This is one of the few type-r exhaust videos that sounds somewhat decent. And the burbles! Keep up the good work!

What a beautiful system you guys have created. Didnt know thats how double wall tips were made so that was an eye opener too. Great work as always LHT 👌👌Looking forward to the drive by videos 🙏

[@LHTPerformance]

[@LHTPerformance]

Thank you. It’s close, but now perfect yet. It will be. We’ll figure it out.

[@Millipoint]

Hey John, hope to see and hear it in action at the firm soon 👍

[@ValkenDnB]

Who knew making an exhaust would be so interesting. Wish you guys got a hold of an 11th gen si and were able to make an exhaust for that too.

[@prm5798]

Really nice work guys, I agree it’s too loud, but you will get it right

[@ozman1975]

You guys are pretty good at this 👍🏼 Can't wait for V2! Nice work!

[@LHTPerformance]

Thanks my friend. It’s fun, plus we’re learning too.

[@ultanwoods]

Good video John 👍

[@PRZJ91]

On the Dyno the valve seems to open at a set rpm for the first movement and open the rest at another rpm/vtec engagement or boost level. Interesting.

[@LHTPerformance]

Once I drive it more we’ll put a GoPro on it and watch the valve. It’s interesting that it’s programmed but on a stock system the noise change is almost non existent. It’s a shame not to utilize it.

[@PRZJ91]

@@LHTPerformance I agree! If it can be reprogrammed that would be pretty cool to set your own parameters. Can’t wait to see it on hondata!

[@LHTPerformance]

@@PRZJ91 Yea. That would be great.

[@TheFK8Life]

I made 547whp on stock FK8 exhaust - once you add a 5" downpipe and 3" front pipe the sound is good but not raspy - stock exhaust isnt that restrcitive really. Was looking at the remus for a valved option but it was basically 3k or so with options 😂 bought a used greddy exhaust to help beta test a new turbo and miss how stealth my stock exhaust was - im making great power with no backpressure issues but its always open and loud. Valved option is a keeper if going to larger piping to keep the sound down around town

[@LHTPerformance]

That’s good to know. I’m not planning on big power as I’d like to take it to the road course and enjoy it. Mid 300s will be plenty, plus I don’t want over heat it racing. We’ll figure out the sound , then I’ll be happy with it. There’s not a lot of power in the exhaust , but there was a little.

[@TheFK8Life]

@LHT Performance stock turbo has more heat issues as the td04 housing is tiny and the bearings/passages are smaller My RV6 R660 is using a td05 cartridge and -10 AN coolant fittings - makes power to 7600 on stock cams On stock turbo I hated the torque spike that blew the tires off - the P600 and R660 are easier to drive and get back on throttle mid corner and corner exit I made 417/420 on stock fk8 turbo e30 ....spools too fast - easily blew my 265 Cup2s off on WOT The FL5 turbo will probably be worse as it's smaller and made for low end torque response which compounds traction issues when you up the boost. Mid 300s on 93 won't even need mods - basic tune will get the job done so should be fun to watch how you like it.

[@LHTPerformance]

@@TheFK8Life Definitely too much low down torque. I’m thinking we may be able to tune some of it out put a little on the top. Once we get the exhaust dialed in that I like it, the mid pipe and down pipe will be on the list. I want efficiency, so a slightly large turbo might be in the cards. I don’t need a ton of power. Thanks for chiming in 👍🏻

[@LunchmoneyH]

1st class work as always, are you open memorial day, I'd likento come in and buy some things since I'm in the area this weekend from VA

[@LHTPerformance]

Yep. We’ll be here.

[@chrisgagnon4608]

Big restriction there at the 3 way joint. Flow will not turn 90 degrees. With the valve closed, you will have a pressure build up that forces the flow to make those 90 degree turns. That's a restriction.

[@LHTPerformance]

Under light load there no issue with restriction

[@Flathers]

I know what you did at the gas station, first gallon goes in truck tank to clear the 89 from hose haha I do the same thing

[@LHTPerformance]

Bingo 👍🏻

[@bandwagon240]

Just like the C8, I wonder if just replacing the tips has any noticeable sound difference.

[@LHTPerformance]

Maybe

[@jefffernandez6679]

[@cybergrindin]

Is titanium lighter? What’s the significance as opposed to what oem uses..

[@jahbrake9791]

[@brettbaskes892]

When will this be available to purchase. This is the best looking and sounding exhaust I have seen yet on the FL5

[@LHTPerformance]

You can buy this exhaust, we’re still working on other ideas.

[@brettbaskes892]

How do I purchase and what’s the price? This particular exhaust? As in the one in this video?

[@LHTPerformance]

@@brettbaskes892 I’m selling for $3000 and we’ll install it if needed. We have $2800 in materials alone and about 40 hours in building it. It won’t be something we’ll reproduce as it’s not cost effective.

[@bamboosho0t]

So will it be a 2.25” branch off from the 3”? I believe that keeps the ratio similar to the stock. Great progress!

[@SHADOWDENNIS]

Awesome car❤

[@derrickyi7433]

have you thought about using the oem honda mufflers for the two outer sides? seems like this would give you the best of both worlds.

[@LHTPerformance]

I’m wanting it titanium. The factory mufflers are a very low grade stainless. We’ll figure this out and get it right. Just a case of getting the right combination

[@derrickyi7433]

@@LHTPerformance ahhh that makes sense!

[@MrRevto9k]

can you guys try a catted/catless downpipe for back to back dyno?

[@LHTPerformance]

We won’t be running without a cat. I don’t want the smell , plus we’re not going for all out max power.

[@rolandotillit2867]

The computer cuts torque in the 'low speed pre-ignition region' they tuned it that way from the factory to avoid LSPI which will put extreme stress on the engine. Lots of tunes give you big torque numbers down low, that's just a recipe for disaster.

[@LHTPerformance]

I understand this and something we do on our builds. Taking power down low on my S2000 was a perfect example, it was wanting to make 300+lbs tq at 4200 rpm’s which is hard on everything. I wonder why Honda put so much in on the FL5 and not the FK8 and run it so lean at the same time. Is it to heat up the cat for efficiency 🤷‍♂️

[@rolandotillit2867]

@@LHTPerformance It could be to avoid LSPI for the most part, the lean area is where the engine has highest efficiency, if you look at any run of the mill BMEP graph you see BMEP is highest at that rpm. Only issue with that is if you run too lean it starts making combustion unstable, a lean misfire is still bad but not as bad as a rich misfire in that engine speed range. My guess is Honda rather have lean misfires than rich misfires because of the damaging nature of LSPI.

[@483SGT]

Always blows my mind how useless the valve is on some cars. My prior bmw and now FL5 are both almost indistinguishable when open yet all my vettes have been night and day like you said

[@LHTPerformance]

Yes. I agree. Seams like a waste of a hood thing.

[@483SGT]

@@LHTPerformance do you think just removing that center muffler after the valve would be a noticeable change for those of us who want quiet mode to stay 100% stock?

I can supply you with a Mclaren titanium valve to suit the OEM motor if you are interested

That would be very helpful for future valve builds.
