Question on removing cats from 08 coupe

[1BADGTS]

DP i would call Lou Ballanger as he knows A TON about the tolerances of the Gen 4 exhaust in relation to PCM codes ect.

Has anyone with a 2008/09 tried a Corsa cat back with high flow or no secondary cats yet? I still want a more aggressive exhaust sound! Thanks

The Gen4 will tolerate the Corsa and Lou's header/cat package so I don't foresee any issues really. With the addition of the Mopar PCM you could go cat less altogether if you needed to.

Thanks Mark. Has anyone tried this and did it improve the volume/quality of the exhaust sound? Thanks

Doesn't Roe offer a high flow cat in replace of the original two. In other words, get the corsa 3" cat back and remove both cats from each side and replace with roe high-flo cat.

Would this combo be OK if we plan on adding the Belanger headers later?? Or would we need some other H/F cats?
