If you think an exhaust leak is annoying, just unbolt the down pipe from the exhaust manifold, then light the car up. youll know what im sayin

The question would be , remove the exhaust from where? On a stock 94 with stock ecu and no other engine management I have heard you should only remove the catback. If you remove the main cat or precat, it may result in boost spikes to 17psi. This can lead to a lot of fun but also detonation i$$ues.

oh ok... i will just leave it then and deal with the buzz of the exhaust. i don't want to take no chances.. my exhaust should be here in a couple days.. hks hyper... anyone know what they sound like?

Which one is the HKS hiper. Any pics going to be taken when you get the cat back put on?

HKS Hiper...used to have it...LOUD AS ***** with a midpipe/downpipe combo. Not as loud as my JIC...but LOUD still.

What do y'all think is the loudest catback exhaust and of course better performance. I would say it's the Greddy Power extream anyone agree...

jspecracer7

To be honest, they all perform the same. BUT...the SOUND and LOOK is what people want. You want the least amount of bends, the least amount of restriction i.e. 80 mm ALL the way thru, blah, blah, blah....

17psi is fun. That is how I blew my first motor. As for the cats I dont use them and I can get 11psi when ever need be no more no less. Gotta love NON-SEQ
