Hey guys just a general question. I'm looking to buy an RSX soon, and was wondering what was the difference between a turbo and street exhaust. I'm going to get a greddy, and they have two options. I understand that the header and downpipe must be different but why would a cat-back system be different? I posted this here because I figure its a general question and I still drive a 7th gen civic .

Could you post up a link to the two exhausts?

A lot of what makes a a good exhaust is the quality of material and welds, the routing of the tubing makes a big difference as well since it determines the quality of flow.

It seems like the only difference is size. I will eventually go turbo but it wont be for a few years. Would I be better off getting the turbo one now or will it make a difference if its on a NA engine?

ask greddy if they would recommend them for NA. if piping is too big, you will see drop in lower RPM
connecting to current exhaust will take some work, naturally.
