    Hey all. Been kickin' around the idea of getting a high clearance bumper from Costal offroad in Canada here and was just reading up on how some folks are doing the exhaust. Seems the majority of folks are just cutting it off right near the rear axle which is fine and all. But the way my ride is set up I'll be sleeping in the bed when I go offroading. Dont want things stinking up if i can help it. I also sometimes throw the pooch in the back and don't want her getting carbon monoxide poisoning when we're sitting at a long light in the city. So all that being said. Has anyone ever consider cutting a hole in the bumper and running it out the side of the bumper? Seen a few guys run their exhaust out the side of their beds on some diesel trucks but was just wondering if anyones ever done it out the bumper. Was thinking about cutting a hole in the slanted part then seeing if they could cut a slot in the vertical sides for steps to get up to the roof rack.

    Any thoughts? I dont think this should be an issue but a second opinion never hurts. Still have plenty of time to mull things over and actually grow a pair and cut up the bed. Also since your reading this, is it just me or is the gap between the bed and the bumper a bit much? Also also how would a guy protect the part that was cut from rust? All that fresh cut steel and what not.

    Thanks all!

    That gap is normal, to account for body/bed flex. Your exhaust idea seems ok. I’d worry about allowing the exhaust flex relative to the bumper and weakening the bumper.

    My plan has been, if I get the nerve to cut my truck that is, to run a pipe as tight as I can and have the tip turn down right at the bumper. Keep it up out of the way, but angle it just enough to where the exhaust pressure will carry the fumes away from the truck. I’m sure I’ll need to put some insulation on the bottom of the bed to prevent it getting too hot. Your idea of a side pipe would work, I’d run solid pipe, to a 6” or better piece of flex pipe, then the tip. Give it some room to move.

    I cut mine off right behind the last hanger and I don’t smell any fumes in the bed when I sleep in my camper shell. The slightest breeze is going to move the exhaust around. I wouldn’t worry about it.

    The gap is normal but it comes down to where you cut the bedside at for the HC bumper. My exhaust is cut right after the axle and I haven't dealt with any fumes from the exhaust while in my camper. I would say if you decide to go thru the bumper with the exhaust, keep an eye on your exit angle compared to the hump that goes over the axle. You don't want it running down back towards your catalytic converter/motor (although maybe unlikely, but heaven forbid you stall in a creak crossing and all the water runs right down your exhaust).

    Something else to keep in mind about the exhaust dump at the rear axle...I've had an emissions testing place tell me they couldn't test my truck cause they couldn't clamp the sensor on the downward tube (lame, so I went to a different location but same company, and they did it no problem thru the OBD port). I may end up having an extension made to slip on for testing, just so I don't have to worry about driving to a different location.
