Question about SR pipes

ck1129 · 12-13-2006, 10:56 PM

Are they only the back on bolt pipes that delete the post cats, or do they replace the resonator section aswell?

mds82 · 12-14-2006, 12:54 PM

they bolt right onto the downpipes from the engine.

good question
thats wat i wanna know too
cuz if resonator delete on eisenmann is louder... i go wit that
if SR pipes wit eisenmann are louder... ill go wit that
plus isnt it just better to have the full catback system in general?
better air flow in general, and do SR pipes have any other benefit other than sound? i dunnno any performance gains? better throttle response? hell iono
but i wanna know soon, cuz i wanna get one of the two done

The SR pipes will be louder than the eisenmann muffler without the stock resonator, weigh less than stock and provide a small power increase don't expect more than 2 or 3 hp and a few ft lbs of torque.

So after the New York meet today it was decided - The SR Pipes sound better then just cutting out the resonators
