i know the bosal high flow cat is coming out soon what would be a better idea i am not worried about noise but i am worried about emmissions what would be better to get a shorty header and a offroad pipe and just change the cat back when it is time for emmissions or wait to get the bosal hgh flow cat i have the borla cat back

Well if your just gonna change it back then get the off road pipe.....it was the best mod ive done yet. Very nice gains throughout the power band and especially on the freeway!
