Folks,

I'm looking to get a little bit more noise (nothing excessive though) from my STi and have 2 options open to me at the moment.

I could either replace the back box for a Prodrive box supplied by Subaru or I can replace the exhaust from the cat back for an HKS system. I'm in New Zealand and there aren't too many places which can help me!

Can anyone offer any suggestions at to what might be the best route to go down? The HKS system (cat back) is twice the price of just changing the back back.

Any assistance would be very much appreciated.

Cheers
Mike

 

If you can get hold of a sti genome back box, then just get a de resonated longer piece, very good set up in my opnion..

 

i've had 2 different milltek systems on my JDM - perfect systems in my opinion - loud when you want it to be but reasonable when just pooting about
