I think i seen on here about putting a resonator on your dp instead of the cat.. My cat went and would it be the same as a cat.. Does the length mean anything..

 

I would just put a new cat in if i were you. It is a recalled part you know.

 

The lsj downpipe has been warranteed for 10 years 100,000 miles recently. Go to the dealership and have them replace it with a new one. Catless sounds like ass on a supercharged balt. The extra 3-4 hp isnt worth the raspy ass exhaust note you will have.
