Hey guys, Im looking to upgrade my exhaust system and i figured if there was anyone to ask about what kinda system to upgrade to it would be you fellas. Right now im running your basic cat back pipes with the stock manifold. I plan on getting a split header and running dual pipes eventually but for now my pockets cant afford that. Anyways.. What do you guys think would give the best performance for my 300i6? Thank you for any help in advance!

if you absolutely must have something before you put a header on it then find the split manifolds off a newer fuel injected 6 at a wrecking yard... fraction the cost of the headers and near same performance

oh and make sure you get an oxygen sensor in it cause you should still have the feedback carb unless youve already gone back to the duraspark2
