Default Corsa knockoff

http://www.ebay.com/itm/OBX-Dual-Cat...19f6da&vxp=mtr

Is OBX Catback a Corsa knock off exhaust?

Yes and no. Dimensionally yes. However, noise reduction strategy is totally different. Corsa uses helmholtz chamber in the muffler whereas OBX uses perforated pipe in the resonators and mufflers with sound absorbing insulation behind them - similar to old glass packs.
I have OBX exhaust on my car and have no complaint. Had to use Torca band clamps because clamps that came with OBX were junk.

The E-Bay price of $494.00 sounds way to good to be true! Can someone who has them tell us more about them? How do they fit? What would you compare the sound to, Flowmaster or B+B? Are they a lot like Corsa for a third the price?

They fit fine. Just buy Torca Thoroseal band clamps and toss out clamps supplied with the OBX.
Sound is more mellow compared to Corsa and not as loud as BB.

more cubes, cams, and compression isn't really represenative of the sound of a stock motor. Your's has a deeper sound then it did last I heard it

I installed the OBX catback exhaust on the '90 ZR-1 I had. I liked the sound, wasn't too loud or quiet (for my taste anyway) and I didn't notice any resonance issues either. I also like the look. I will probably get this exhaust again once I get another Z.

Like the others have mentioned though, the clamps that come with it are complete garbage, you have to get some quality ones. But the exhaust system itself seems to be pretty well made for what it is.

I have the OBX Exhaust on my 91 Z and love it! I drove Yun's ZR-1 before with the OBX and thought the sound was perfect. Here is a video of my Z just after WAZOO helped me install the OBX exhaust - https://www.youtube.com/watch?v=9Btec_YDAfs

After 2.5 years the exhaust still looks brand new and sounds just loud enough without being annoying when carrying on a conversation or listening to music.
