SCS Catback for 3.0T VR30 Q50 Q60 | SCS Custom Catback SOUNDS SO GOOD!!!!

After much demand, here it is!! The video explaining how the SCS Custom Catback fits and sounds on the 3.0t Q50 and Q60!! Replicate at your own risk. Now, we haven't yet seen this setup on the dyno for the 3.0t, so we cannot be certain in terms of performance or peak HP and TQ numbers. This is where the variations mentioned could be beneficial.
If you are keeping factory cats in place, consider just installing the Boral mid-muffler OR just the flow fx resonators. If you are going with lower/full downpipes, consider doing the complete system. If you plan on tuning the car, consider going with the 3" variation in increase flow. If you are more concerned about hp numbers than exhaust note, you may want to use an x pipe rather than the borla and simply go straight back to the flowfx resonators, which won't restrict flow at all--all in 3" diameter. See 3 inch options below.

What we need now, is dyno results for this setup and it’s variations. We know now that it sounds good, but we need some numbers! Check the description for some thoughts regarding increasing flow and different combinations.

Thanks for checking it out! But see the comments from Matt--he has one of the cars in this video and he estimates he's at about 415hp with his mods and tune. I believe he has 2.5" as well. May be able to pull a bit more with 3" and foregoing the borla, but you'd have to consider a change in overall tone if you went that route.

Hi SCS! I am considering on doing this exhaust setup on my 2019 Infiniti Q50 sport rwd(3.0), it’s completely stock performance wise and I had a couple questions. I want to keep cats and do upgrades to increase power in the future, by doing this complete setup (Flanges, flex pipe, borla mid muffler, resonator and exhaust tips) will I get a good sounding exhaust or would you recommend just doing an x pipe instead of the borla of magna flow? And if so which out of the 2 (Borla and magma flow) would hold better with performance upgrades and sound better? Thanks

[@SpeedCultureStudios]

Yes, I would recommend using an x pipe rather than the mid muffler. And I would go with 3” rather than 2.5”, so just be sure the x and resonators you choose are 3” in diameter

[@alex-ld9nu]

Ok great thank you! I found the x pipe from total flow 3” would you recommend this one? And regarding the flanges and flex pipe would you be able to attach links to the ones needed for the 3” setup, greatly would be appreciated!

[@SpeedCultureStudios]

It would be ok and people have done that, but if you like a more aggressive tone, you can do a regular x pipe instead of the borla and then use the FX resonators out back. Turbos act as mufflers essentially so the borla isn’t all that necessary if keeping cats

how would two flowemaster super 10 series fit with this and leave one valuve open 🤔 aggressive sound?

[@SpeedCultureStudios]

I'm sure it would be pretty aggressive, but depends on whether or not you have stock cats as well.

[@EnciStreams]

when you get to talking about all the different pipes i tend to get lost sometimes , basing off your other videos for your custom exhaust , if i do the borla , flanges , resonators etc that you have listed in your other videos with flex pipe will it still sound good and have that aggressive tone to it without a whinny tone. in your other video you have stated you’re more into deep older tones , and that’s how i would like 3.0T to sound , any other suggestions

[@SpeedCultureStudios]

That is the setup the guys have in the examples i provided in the video. If you like that tone, do this setup. It's hard to make the 3.0t lower and more deep, and the turbos muffle the sound quite a bit, especially if you have factory cats. If you are keeping the cats, install the x pipe and just do the resonators out back if you want it a bit more aggressive.

Flanges are tough to find at the moment. Many exhaust shops will have them. Maybe just call the shop you plan to go to and see what they have. Also your downpipes might be 2.5” so you could potentially just get the 2.5 and have a coupler go to 3” for the rest.

[@SpeedCultureStudios]

It seems to work best in reverse order for awd cars. Shops are scared to install it as designed, but it’s fine. If you’re looking for an aggressive sound, maybe just go with a plain x pipe and flowfx resonators. The borla may tone it down too much for your liking.

It really wouldn’t make sense to use 3” because you’d be shrinking it down to go through the resonators so it sort of defeats the purpose. It’s not really necessary to use 3” either.

I have a 2016 3.0 Redsport AWD. Would it make any difference in sound whether I put the flow flex resonators under the car after the x pipe vs all the way at the end in place of the muffler?

[@SpeedCultureStudios]

It does actually make a slight bit of difference. With the resonators at the rear, they help pick up the rasp before leaving the tail pipes. With them under the car, the system can generate some raspy frequencies as it travels through the rest of the pipe before exiting.

I like your exhaust set up, but with turbo engines back pressure is bad, but scavenging is good. What are your thoughts on this. Would you say an exhaust that goes 2.5" from the down pipes to the resonated X pipe and then expand to 3" about 2 feet from the X and expand to 3.5" for the remaining distance to the rear would help with scavenging while reducing back pressure utilizing a varying size exhaust system. I'd love your thoughts on this.

[@SpeedCultureStudios]

From what some testing has shown, there is little if any scavenging at the point of the y/x pipe, so what my suggestion generally is for the 3.0t, particularly if you will be modifying and tuning, is go from the 2.5” downpipes to 3” pipe. and because the turbos have such a muffling effect, I would use a typical x pipe rather than the resonated x. My opinion is that a 3” dual catback is sufficient, but I don’t think 3.5” after the x would hurt anything. In an NA 3.7 tested by motordyne, some of the best results were achieved with a system that gradually increases in diameter-but more of in a cone-shaped fashion rather than stepping up at certain points. Does that make sense? Id love to see some testing done with what you’ve suggested!

[@dbsimms63]

@@SpeedCultureStudios since I don't have my car yet, having to wait until after I close on my house, what is the size of the stock catted down pipe? I've read it's quite small around 2". I was even thinking of going with 2.25" from there to a stamped 2.25" x pipe then go to 2.5" straight resonators off the x, they would be about 24-28" long and then go 3" off of them all the way back. That would be a good progressional size increase and it should reduce cost some since the stamped X and straight resonators are cheaper.
