im trying to get a hitch installed on my k5 ( a class III is good enough for using to pull/ get pulled outta mud right). and right now my flowmaster exhaust is in the way so im gonna need to cut some of it off. what i wanna do is just cut it off right after the mufflers and do turndowns but my parents wont let me cuz they think alot of fumes are gonna leak in so they wanna try and get it to come out 90 degrees behind the rear tires instead but i know that if we do that, its gonna be in the way again for when i put in a shackle flip. so i guess my questions are: is a class III strong enough for getting pulled out of mud/ pulling people out of mud? & is it alright to do turndowns after the mufflers (they are about a foot before the rear axle) on a k5, or should i try to run the pipes out the sides somehow?
