So there are many of these reviews, and thought I would share mine. I had my ebay exhaust for about a year now, it sounds great, holding up just fine, and fitment was perfect. Well it went through a overhall, wanted to take out the cat, and resignators, and so I did. But back to the description, when I first got it, it was a true 3" cat back, no bottle necking, fitment was perfect, and sound was great. After a couple months, it did have some rust spots (surprise surprise), but when I did the overhall, I sanded and painted high temp flat black, and it now looks good, and no rust what so ever.

Overall: I like the sound and quality of this exhaust, and many others do too. I would definatly buy this exhaust again, and recommend it to anyone looking for a cheaper alternative.
