i got one , on my 33gtst , oh man i tell they are excellent, not to loud , its only loud when u floor it! and it sounds sick! like a deep roarr, but i also have it running with a 3inch front pipe & a 3inch high flow cat so basically i gota turboback exhaust system. Its a very simple step to install, from the cat of the flanges, unscrew the bolts and put it in the hangers and hoooks. make sure u gota alot of wD40 good luck man.
