Right,

The Blitz Nur Spec is getting on my nerves now on my STi 2002, its so loud.

Can some one reconmend me another system must be 3'' bore and good enough to flow 420ish bhp

Thanks

 

Hi there

We've used Revolution which has flowed enough for 555.5bhp and few guys has run those exhausts at high 600bhp,but we are run too HKS 3" silent which has been OK for 490bhp without the issue

Hope this helps

Thanks,Jura
