Finally. Ive been wanting a 3" exhaust on my car for a minute but i just havent had the motivation. I have 2" straight back to the stock muffler. AMAZING work, much better than 2 pipes in my opinion.

Do yourself a favor and get either a chambered muffler or a non-straight through "turbo-style" muffler for the rear can. No matter how big you make them, if you only have straight-through mufflers your car will always be too loud.

But will that hurt performance? How about boosted applications?

No idea on a boosted car. On an NA car no issues.

My DSP car has a big Borla straight-through as the resonator and then a Flowmaster chambered muffler at the rear. It sounds great.

Or you can try a Dynomax or summit "turbo" muffler. Just do some searching.
