Start a heart transplant mid November with LS1 and SM465 :-)
Currently mine dump under, just before the rear axle. I know this isn't ideal but it works for now. I will be changing it to dump just after the rear wheels out the sides.
On edit: If you haven't purchased the headers yet, try to get headers that have the collectors coming straight down when attached to the motor. Mine are angled and make it a bit more complicated to attach the pipes.
Dump the exhaust just behind the rear wheels about in the middle of the tire, that way the exhaust is kind of caught in the slipstream of the tires and taken well to the rear of the Jeep. I had the exhaust coming straight out the back, and was nearly overcome by fumes.

This is key right here and why most factory systems are set up this way. The fumes can get really bad if the exhaust points straight out.
Thanks, that is what I work wondering about them coming straight out the back. I will plan on taking them over the axle and out the sides

I get it, I'm a Jeep owner and ad-block detectors kinda stink but ads are needed on this site. This is a CJ site, all the ads are set for autos (some times others get through.) I cannot make them just for Jeeps but I try.
