Custom 2.75"/3" Exhaust finished

Just got the finishing touches for the catback exhaust all done. Stock manifolds/cats, dual 28" Magnaflow resonators before the OEM X-crossover, 3" crimp delete with flanges and a Corsa 2.75" Sport Axleback with black tips.

Absolutely no drone, smooth tone, no rasp. You can hear the X-pipe clearly (the crossflow noise at the down rev portion). Loving it!

Now the obvious part, she needs a wash badly! Got stuck in a nasty rainstorm on the hwy and she is filthy. Wont be for long!


Cold Start:




Warm Revs (Enjoy the sky, camera was pointed up on the driveway ):

Nope. No need or desire for it. Zero drone, all the flow, all day sound.

The NPP isn't really needed until you install headers. Some would say its still not then but it doesn't get really LOUD until you install headers.

Absolutely, which is why I’m wanting to hear his with them…i think it might just work lol…the corsa sport instead of extreme, and the magnaflow paired with it.

My guess is it’d be tits

Wow man. That Corsa is special sounding. My car does not make that noise you're referring to on the down Rev with S type. Great sound.

Thank you! My 370Z did this when you had an x-pipe and straight through mufflers too, I personally really like the sound, like its hissing at you.

Cold start video added. I'm in love. Stoked to hear it with the 2" longtubes. I have room for two more resonators if needed and the car will have UHO Green Cats (850hp per bank) so it should be louder but not brutal.

There is ZERO drone with the current setup. Super refined sounding. Hats off to Corsa for building side branch resonators inside of a muffler. I had the same setup on my 370Z but the side branches were off of the rear muffler delete not inside the muffler, less sleek but it worked wonders.
