Does anyone have any experience with a CGS-60049 catback exhaust? I tried doing a search on the forum but couldn't find anything. I'm guessing the HP and gas mileage gain claims are a little far-fetched, but since I don't have much knowledge on catback exhaust systems, any information anyone has will help. Since it seems like a lot of the people in the group have a catback exhaust, it must be an improvement over the stock exhaust. I found the one below on Ebay. I have an 08 H3 and I'm hoping to do this myself. Thanks for the help.

 

Here's the one I found on Ebay..

As it turns out, there are already threads on this, so I got my answer.

 

Catback Exhaust is a term not an actual type of system. Your OEM is a "Catback System" as well. It just means thatall of the piping is "replaceable" after the catalytic converter which is technically you are not legally allowed to remove.
