    If you don't have a V then you have the 4.6 LH2 N* not the 4.4 LC3 Supercharged N*

    Either way you buy the V exhaust and mod the hangers it works just fine.

    I also have the AWD model, is that going to change the hanger angles any? What's involved with modifying the hangers? Have you done this same modification?

    No I bought the right exhaust for our cars Corsa. There's a few threads floating with pictures I believe but any exhaust shop with a brain should be able to mount the Gibson. Also awd and rwd makes zero difference past the rear axle which is where both Gibson and Corsa mount as they are axle back not catback. Borla was the only catback and its discontinued.

    I recently had a pair of Thrush turbo mufflers. I noticed a gurgling sound between 1k and 2k RPM at acceleration. The performance is not affected by the noise but the noise is just annoying. Has anyone seen or heard of this issue after installing exhaust?
