OK, what exhaust sounds the most like the rally cars'? I absolutely LOVE that sound!

 

It's not just the exhaust; rally cars sound so nuts due to ALL the work done on their engines (which is much too extensive for me to cover in depth here ) Personally, though, I'm partial to the sound of the HKS Hi-Power, the Blitz Nur-Spec, and the Kakimoto GT 1.oZ (perhaps the loudest, bassiest exhaust availalbe for the WRX haha).

 

hmm. the mis-firing system sounds dope.

 

I use the TurboXS TBE (with the RFL muffler) on my rally car. It sounds sweet.

 

straight pipe? straight pipe to 1 muffler? thats about as close as you'll get without anti-lag and major engine work.
