Are headers worth it?
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
3.0i z4, every aero mod on the planet, stage 3 intake swap + tune. Remember guys, you can't fail if you don't try.

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 ?

You would have to check with your local friendly garage
