just completed my exhuast today and it sounds so deeeeeeeeeeeeeeeeeeeeeeeeeep and nice, have any of you guys ever installed a hi flow cat or just gutted the cat like I did and smell the exhuast gases. I think I'm just going to just buy another cat becuase I can't take the smell from the exhuast and the Check engine light, any suggestions

 

No i have never done that before but was wondering did you get any more performance out of it? if so is the performance worth the smell and noise?

 

well I noticed a major difference in top end speed but as for as take off I believe I lossed a little power but the sound of the exhuast is very very very deep and nice

 

i have gutted the cat and just got rid of them, the smell you are smelling is just the unburnt fuel... I Love that smell along with the smell of fuel in the carburators

 

someone was sayin on vwvortex how they lost power doing this so they went back to the stock cat. if u need to buy one i got one i can sell u bc i got a random tech.

 

he probly lost torque because of back pressure

 

So, what about Milltek's Hi-Flow Sports Cat? Would that be the same? Anyone have one? Recommend it?

 

you do need backpressure, if you have the right muffler and the right amount of air comming in to your motor, you don't need your cats.. They are only there due to the government, cars only recently have had cats installed in them...

 

we should screw the down pipe and cat and let it spul out after the manifold

 

when u get rid of/gut your cat or get rid of your muffler, you lose alota back pressure and that results in a loss of low end torque, but u make more horsepower higher in the rpm range, my friend had a system like that on his camaro, did it more for the sound though
