Borla Exhaust

I love the low tone of the system which gives it a V8 sound and feel. I can really feel the difference and would recommend it very highly. It's everything I had heard and more..AWESOME!

Borla = best

If you want an exhaust that is not extremely showy, or too obnoxiously loud, while at the same time being quality then this is the exhaust for you. I spent about two weeks trying find the right exhaust for my 350z, and I couldn't be more pleased with my purchase. The low revs on this exhaust have a deep growl, making it sound like a v8, and the high revs give it a track car sound. Another plus is the fact that it is true dual giving better performance, and it isn't that much larger than stock.
