Didn't use the paste either. I smelled carbon for about a week, but after that- nothin.
The FSWerks race exhaust is awesome. Their is none of the "BRAAAP" noises like a lot of Hondas and Nissans; nor is it going to give a "TIN-Y" kind of sound (sorry can't come up with a better description than that). I've been very happy with mine. It has a great low-baritone sound at idle, but when you get on the throttle it comes alive. One thing I will never get over is simply starting the car- I love tappin the gas and hearing the exhaust gurgle and pop. ENJOY MAN!
