VTEC exhaust on an SI? - Honda Prelude Forum

Brady92/4WS · 03-01-2002, 05:43 PM

A guy i know has the greddy PE on his 92 si4ws, and he said there wasnt any modification involved. Well anyways, i figure there must be some modification needed otherwise the manufacturer wouldnt say vtec only. I'mjust wondering if any of you guys out there have VTEC exhaust on your SI, or if you know what modification is needed.
Thanks

im pretty sure you wont be able to have a vtec exhaust on an si, because im having to change everything to vtec on my old si car

I have one. The greddy PE and all that is required is to dremel the holes to fit with the converter.

Another thing that might work is to get a vtec cat converter to go with the vtec exhaust
