Get rid of the cat. Then after you have that done, you can get rid of mine too:lol3: Not sure about clogging it up, Mine hasnt yet. I have to agree, you sure can roll coal with the jr. and a manual trans:thumbsup

I've got 10k+ miles with Smarty and the cat, and have yet to have a problem.

Mine's Still got the cat and I've never had any problems. Smarty will let her roll some JET BLACK smoke even with the cat.

eventually it will clog the cat, and the cat will become junk my brother used to run his tst on 7 and let the coal roll and his cat started rattling and we took it off and the ball was rolling around in the cat
