Hello to everyone, I just joined the site and had a couple of questions bout exhausts. 1st off my new LB7 diesel is stock and its quiet as hell (my dodge was way louder) and it is pissin me off. What would happen if I just cut the muffler out and had it as a straight pipe (fume issues)? Would it sound loud and awful, or just loud as hell? And would I gain any power or damage anything from a straight pipe? Wouldnt it affect backpressure ? Another question is could I maybe just drill out the muffler? I dont do a hole lot of mechanicin on my truck so I am guessin that a few holes in the muffler would be the easist thing for me to do (a redneck friend of mine told me but his truck is worth 700 bucks mine is worth 20k, so I dont wanna destroy it). Also eventually I wanna get smokestacks (income tax return time) so this straight pipe thing would just be a quick fix for my sound issue, but itd still be a 3 inch pipe, the stacks will be 4 or 5 and they will be professionally installed (by a real mechanic...lol). Thanks for any input you can give me.
