Did a bit of searching around and couldn't find too much information on this.

Has anyone researched/know the performance gains on a Greddy SE exhaust system for the coupe? I'm thinking of getting one but contemplating between an HKS and Greddy. I know traditionally axle back exhausts don't offer as much performance gains as cat back but is there a serious performance difference between HKS and Greddy SE?

 

hks looks mean...

 

Dont buy HKS Hi Power Exhaust If your car have 4WAS because it will not fit

 

It would be stupid to buy an exhaust over the other for performance "gains"

Pick the one that sounds nicer to you

 

Performance gains would be a good reason to pick a good exhaust if there was a major difference. The simple fact is, they are all going to be very very close in results.

 

Thoughts on Tanabe? It sounds nice, not 2 loud, more of a re-fined sound, the way the G should have come out. I think there is a tanabe y-pipe, and midpipe in the process. Any big difference if the y or mid pipe are added? Looking for a good deep/pleasant sound. Will these pipes make it sound like too loud?

 

if you are just going for a deeper sound you could also think about adding HFC's to the mix. adds deeper tones and doesn't make the exhaust too loud either
