OK DONE. ONTO THE SOUND REVIEW!
I tested it out. Soundwise.... it's nice. Keep in mind that I have a stock SE exhaust and an open element air filter (it has some supposed heat shield on it).
On a car, there are 2 places that sound is loudest at right?
The engine and the exhaust.
The engine itself doesn't sound much different. The only real difference is that there's a low gurgling sound when idle (think of old fully restored carbureted caddy). However, on WOT that gurgling sound gets a bit louder (I think). It doesn't sound menacing, just a little mean.
The exhaust... !! HUGE difference. It sounds like it aint stock no mo. With the WOT it sounds like my rear bumper should be hanging some 1000 lb gorilla nuts.
As for performance.. ehh I can't really tell much of a difference so far. My morning commute will tell me what's up though. If there's a response or two, I'll post from work and let people know how low they're hanging.
