cherry bomb in place of cat?

i decided that im getting rid of my cat and am just gonna put a pipe in place of the cat but i had an idea and didn't know if it was a stupid idea or not. what if you were to take the cat off and run a glasspack or something in place of the cat and then just deleted the muffler under the gas tank and have the exhaust pipe straight out the back? i didn't know if i would loose power or something if i did this so i just wanted some opinions.

It's been done, it works, it doesn't sound half bad. Actually I see more single exhaust ran like this than anything else on these cars. I've personally used a glasspack on an import car where the previous owner had scrapped the cat, it takes the horrific cackle out of the thing and sounds stock that way.

Re: cherry bomb in place of cat?

Why do you want to remove your cat? Please be a responsible hot rodder instead and replace it with a higher flowing aftermarket cat, such as from Magnaflow. Cats are required to be on all street cars that came with them (that includes all thirdgens) in the United States. Its a federal law, regardless if your area does emissions tests or not.
