I get asked a lot about my exhaust system, so hopefully this explains it in detail. So I pretty much went straight pipe all the way back.  No cats, no mufflers, no resonators, only an x-pipe.  Results are interesting.  I am finally able to get away from the last bit of Livernois parts I had on this car (full turboback system), or should I say, re-branded Corsa system, LOL.

It was all done by a guy named Alex Gutierrez who has a shop called Big Head Motorsports.  Super talented welder.  Only online presence he has is Instagram and Facebook.  He does a lot of high end drag race stuff and his shop is 3 minutes from my house…that was sweet!  I’m going to tag him to do a lot of my future work, i.e., turbo manifolds, intercooler end tanks, and maybe something trick with the intake system.

It’s 3″ all the way to a set of 3″ bellows, then transitions to 2.5″.  There’s an x-pipe right after the bellows and then out to the back it ends up with 4″ diffuser tips. 321 stainless steel was used on the test pipes as it retains heat better than 304 stainless, thus making the need for ceramic coating unnecessary. The system is 304 stainless steel for everything past the bellows.

Make no mistake, this thing is pretty loud.  However, drone is non-existent at cruising speeds,  it isn’t raspy at all and  has a good bass and tone to it, which I’m kind of surprised about actually.  It’s just LOUD when you step on it, lol.  Which I don’t mind so much.

Anyway, the quality of workmanship is out of this world.  It’s built for performance and maintenance will be easy with all the v-band clamps used instead of slip-fits and flange joints.

Some sound comparison videos:

I used a GoPro Hero6 Black utilizing the on-board microphone and mounted to the vehicle here:

For the telemetry, I used the Torque Pro app and used a screen recording app on a small tablet.  Editing of the videos was done only to get sound from the GoPro to sync with the video of the tablet.
