Opinions on this? Better power (especially with turbo) smell bad? Any other concerns??

Thanks!

 

I did it awhile ago and I seemed to lose some power down low. The sound was awful and I really didn't like it so I got a high flow cat and put that on. I think you would see more gains on a boosted motor and the sound might be less noticeable than on an NA car. JMO

 

Bad smell, nasty color out back.....stains the bumper.

$3,000 fine for having a gutted cat.

ANd it is bad for performance because it is an open boxy area in your exhaust track. Just build a test pipe if you want to skip the cat. Otherwise get a highflow cat.

 

Damn, I hope it works out ok for me. A friend already punched my cat out for me. I guess I'll find out after I get the motor back in. Anyone with a turbo running a test pipe? Get more power? I think I'll be welding a pipe into the cat, so it doesn't restrict flow.

 

test pipe, gutted cat same difference... either way its good for turbo, but leaves a mess on the car

 

Test pipe

 

Test pipe is good - just hope your car isn't white like mine

 

Seriously, a test pipe does nothing for a NA car. If you're at the track and trying to squeeze every ounce of power out of your engine, then that's cool. But otherwise your just polluting our enviroment.

 

Punching out your cat seems like"cruelty to animals" to me....
