Twin Turbo exhaust setup
 

What are you guys running on your twin turbo setups or turbo setups in general? I have a TT car running straight 3 inch out the back through a breathless defuser. It sounds amazing and the turbos hum through the exhaust at idle but it drones pretty bad. I have some 3 inch borla XR1 mufflers but I am scared they might kill the sound a little too much. I was thinking about adding an x-pipe and some vibrant race mufflers or resonators.

Would love to see what other people have done.

I'll be copying my friend, JDS99 (Jon) running 3.5" exhaust all the way out with cool copy of the Corsa Extreme method which uses a Hemholz resonator as a muffler that's tee'd off the side of the pipes. It's worked very well for them.

Is there room for that setup with a c6?

DMC Racing did mine. From the turbos to the mufflers its 3 inch stainless that was made to be sectional using V-bands. They were able to fit it all around the 4L80e swap which is no easy task. Having it sectional is absolutely amazing, but not cheap.

My mufflers are left over from the old exhaust that was 2.5inch. They are a one off set of Ti mufflers from Borla so replacing them was not really an option. Car is whisper quiet with the mufflers on. DMC also made a set of stainless 3inch straight pipes so I can delete the muffler restriction at the track.

3" downpipes, 3" C6Z x-pipe, 3" over the axle tailpipes. Drone is controlled with these custom built Helmholtz resonators.

Im building a 4l80 with a rear mount turbo right now. I feel your pain. Looks great :thumbs:

Any one use these?

If they work as good as their resonators they'll work great. I still think you should go 3.5" if you're shooting for big power

The exhaust is only dual 3 inch. Figured it would work best to keep it consistent rather that step up at the muffler and step down.

I meant all the way back

Using Kooks on my vette :D

Where are they at? Is that them above the tips?

Just past the 9 inch.

may i ask whats the smell like without the cats?wanna know before i start my new 3 inch exhaust

It smells...for me it was bad but I run a bit rich. I’d go into the office in the morning and people would ask if I just came from a garage due to the smell on my clothes. Cats today are pretty efficient. It was worth losing a few hp to keep them on.

No issues with smell with my setup. I mean, if I stand behind it while its running for a while sure....but I'm not sure why you'd make a habit of doing that.
