Nicky D's Review

Summit RacingSummit Racing Verified Purchase

Takes the edge off of a crazy loud system. I used it as a replacement for my resonator on a 3" system with no muffler on a Civic. I think it's better for a tough sounding V8, not a 4 cylinder with no rumble. It did make it sound less ridiculous and a little deeper though. I love Borla.

But I didn't quite make the 103dB limit at Laguna Seca. This muffler did the trick. When I needed it quickly, Summit had it in stock and we had it the next day via ground shipping (Northen California). ...read more

not for 370z

Summit RacingSummit Racing Verified Purchase

great looking piece but won't work for a dual 3" exhaust on a 370z. not enough room to place them side by side like they have to be. totally my fault being a novice. borla needs to make a dual 3" in and 3" out muffler.
