The thought of 15 more ponies from some tubes sounds all good to be true. Has anyone actually dyno'd their N52 before/ after headers + tune? Also, im guessing it will probably smell like sh*t right... Considering getting headers and installing some aftermarket straight-through mufflers to quiet it down a bit

Only if you do a cat delete . If you do the headers you should put some cats in a bit further down the exhausts . Something like a 200 cell race cat .

Thanks for the recommendation mate. Will I fail emissions still with only secondary cats ?
