I installed the Borla Atak series muffler. I fabricated my own piping at 2.5“ diameter instead of the usual 3” that they sell as a package on most name brand performance systems. I just wanted sound more than anything and not have to pay $1k for a performance catback setup.
I’m not even sure if it makes much a of a performance difference, what I did alone helped with MPGs. Can’t imagine spending $$$ on a complete catback system will make any difference with or without a tune.
I spent $250 on the Borla Atak Muffler and $40 on black powder coated exhaust tips. Everything else (piping and hangers) I got from my families shop.
I also did a resonaltor delete. This will enhance your muffler sound. Not sure how loud it is with resonators. But overall this setup is loud, not annoying, and does not drone what so ever. However, It will get loud when you step on it.
I’d love to hear other ideas and recommendations if anybody purchased a performance exhaust setup.
