i have an 04 mazda 3 2.3 hatchback and i've got a k&n cold air intake and a magnaflow exhaust system on it, and im planing on getting a 09 speed3 this summer. I was wondering if i can take the intake and exhaust off the 3 and put it on the speed3?

 

You can't use the cold air intake due to it being too long and shaped to hook up to your intake manifold not your turbo, and you could possibly use your exhaust if it the same length and bolt pattern from your exhaust manfold. I'm not sure.

 

alright thanks man.
