View Full Version : hi flo cat or straight pipe??
what do you guys have? does changing the stock cat converter to a high flow one make a sound difference? what about performance? what would you do....straight pipe or high flow cat converter? is the straight pipe worth the emissions risk??

i replaced my cat, made no difference to sound unless you change your back box too...
on the dyno it made an extra whopping 2BHP difference - leave it on there imo.
