Hey i have a 97 GMC 2500 extended cab with a long bed and i was thinking bout putting 2 5" stacks in the bed also. I think that straight stacks would look better then bent tips but was wonderin is there any problems with rain/snow falling and building up inside the pipes?? or any other pros and cons of putting stacks onto my truck

 

Also does anyone have pictures of a similar truck with any stacks so i can get a better idea of what it would look like?????

 

No rain problem here... Most drill an 1/8" hole at the lowest point in the exhaust to drain.... PS this is a Dodge site so probably not too many GMC pics with stacks...

 

thanks ive been wonderin bout the drainage for a while but that makes sense cause the flow will be to fast for a hole that size to really matter

 

welcome to DTR. adding the 1/8" hole is what most do like stated above, and you are right that a small hole of that size will not adversely affect anything. best thing i can say for you with a gm question on exhaust stacks, is to get ahold of a diesel world or power mag and look towards the back for vendors and links.

 

LOL....BBIIGG stack.
