The 401 and the 404 are both High Ways up here and I like to avoid the 401 by taking the 407. LOL

You could finger stick it and then loose the kitty. You can order your kittyless pipe from one of the vendors. I have an MBRP 4" kittyless pipe on mine.

Also, if you finger stick it, I also recommed getting an egr blocker plate. The soot that passes through that egr is nasty and I can't believe it is healthy.
