I want to add at least 25whp over a stock M3.
With any luck my planned mods (TMS pulley, dry filter, GIAC software and Supersprint cat-back) will get me there. I would consider removing the secondary cats but I don't want to touch the primary cats. This is because I don't want added noise or smell and I already feel bad enough for how un-green the M3 is
Unless you take out the cats you'll have a hard time getting there. Tune might add 10-12whp. Filter, pulley and axle back exhaust add pretty much nothing.
My 100cell cats don't even smell that bad. I barely notice it. Full Akra exhaust and Powerchip tune will give you 40whp+ over stock.
