Does anyone know if replacing my standard STi4 centre pipe (resonator, no cat) with a straight through pipe will make much difference to performance or sound ??
I have scoobysport downpipe & back box & am looking to maybe replace the centre now.

Thanks

Tiddly bit more performance (really tiddly), and a bit more noise (should be slightly 'harder' sounding). But not a lot!

 

Not sold it yet then....
Great looking motor...

 

Not yet Dave - looking to keep it a while longer now - although if the right offer came in then I would be silly not to !

I replaced mine with a straight through pipe, and to be truthful the hassle removing it out weighs the benifits. Ive noticed no real sound difference (possibly alittle more bubbling) and no noticible performance.

I wish id left mine alone!!!

 

Thanks guys. Think I might give it a miss (gotta start saving for a MY03 STi with PPP !!!)
