I have a off road h-pipe and dumps.I have had dumps on all my trucks with no fumes coming in the cab..I am starting to think that with the car being so low is the problem..The fumes are kinda heavy at times..Right now they the fumes are just exiting right out of the muffler and right at my axle.
do you have turndowns cuz if you dont it is not a good idea to have the mufflers pointing towards the rearend.Thats putting that much more heat on the rear.
