You really aren't going to get too much stainless steel at your price range.
Stainless catbacks are all over 500 bucks.
As far as 3+ inch tips, it's all in personal tastes, but IMO big tips don't look natural, kinda a ricer mod to do big exhaust tips with no performance gain. 3's i could tolerate, 4's are just plain idiotic.
thats not exactly true...i can get SLP LM1 catback for around 500$ and i think i found a guy thats sellin new magnaflow magnapack catbacks for 350$ or 400$....im waiting for his email back. does anyone know exactly what the magnapacks sound like in person? if you do can you compare them to another type of exhaust so i can get an idea...
