Design Input for aftermarket exhaust configuration?

I'm working next week with a major exhaust manufacturer to develop a prototype exhaust for the Jeep Commander.

I am curious, as to what material and/or design is recommended for a vehicle that will see about 25% off road usage on moderate trails, rocks, mud, and occasional snow.

The stock exhaust tip doesn't presently show. It is kept near the rear bumper at exit.

I'd like to see a tip (or dual tip) protruding, but I was wondering if this would radically affect the departure angle, and also be subjected to many impacts.

Also wondering if side or rear exhaust is preferred, and whether stainless steel is significantly more durable in a water/mud/snow environment than aluminized steel.

I'm inclined to go dual tip, side exit, stainless. Any suggestions would be appreciated.

The flatter the better so this doesn't happen:

As for the tip keep it away from the bumper slightly so when you do hit something it has room to flex. Of course sometimes it just doesn't flex enough and ya get some dents:


Go for stainless steel, will last much longer.

You never said what engine this will be fore, I assume the hemi? I wouldn't go dual tip for any engine but the hemi.

Thanks for the tips and photos.

This will be for the 5.7L HEMI.

Dual tips a possibility.

Gibson Performance completed the prototype exhaust on my Commander Limited. It is a single tip exiting out the rear. I had a problem posting pics.

It sounds absolutely crazy. Sounds really good as a matter of fact. A little on the loud side, but sounds very deep and throaty. It came out really nice.

I'm having a problem getting my photos to upload into Photobucket.

I will try again later.

Happy Holidays All!

Okay, it took forever to upload, but here is the first picture showing a side view of the new exhaust.

If yours is still a prototype, why not pick a standard size hole-saw, make the tip smaller than that, and supply a small stainless trim ring.

If there's clearance to get the pipe up behind the bumper, why not have it exit THROUGH the bumper. Looks different, and full clearance out back?

That would be a great design.

Mine is a prototype for mass production. Not sure if the cutout would interfere with the rear parking distance sensors.
