My exhaust was to free flowing to get the higher numbers. I had the Greddy.
The sound is perfect. Apt of that again depends on your exhaust. But ultimately it's up to you.

The only thing I'm worried about is noise. I'm running the HKS hi power which I would say is pretty free flowing already together with Berks HFC. I'm hoping to gain a little more noise at lower rpms compared to now and more power of course. Deciding between either F.I long tubes or these Z1 headers with test pipes. Just worried that the test pipes would be too loud cause people are saying they're a LOT louder.
