I just bought an 06 F4i and im looking to put a new exhaust in. I have no knowledge on the topic so any suggestions would be appreciated. Thanks

 

Please search the forums, this topic has been beaten to death by midgets wearing snow suits in the jungle.

One bit of advice you might not find is that with your 2006, you have an 02 sensor built into your exhaust. You will need make sure to buy an exhaust that accommodates it.

 

I put a yoshi carbon fiber slip on on my 06 f4i. Not only does it look sweet but it sounds perfect.
