View Full Version : Exhaust in cab?
06-08-2012, 04:09 PM
On my '87 Burb I have a tailgate with the roll down back window and a single pipe exhaust dumped before the rear axle. I can't drive with the back window down because the exhaust fumes come right in. I never drove with it down when the pipe side exited behind the driver rear wheel to know if it did it then. Can someone tell me if it can be avoided. I was planning to revert it back to side exit but don't want to waste money if its still going to result with fumes in the cab.
When we had our 90 V1500 Blazer, when the rear window was down, exhaust fumes came in the truck. Not very nice during good weather driving.

I dont see how if its exiting out the side, and you are driving, how it could come in the back window... unless there is a leak or something somewhere.

Lakes pipes. That'll solve everything.

side exit behind the rear wheel like stock, only way to reduce or eliminate this

the second pic of the red suurban has the air deflector you need to avoid the exhaust coming back in (http://bringatrailer.com/2011/02/01/nicest-we-have-seen-1983-gmc-suburban-4x4/). it basically forces air past your window to stop exhaust from coming back into the cab. i'm sorry but i dont know where to buiy one unless you have a junkyard that might have a decent one still.

Just googled to find one with no luck. Guess I'll be hitting up a pick-a-part soon.
