I just bought an '06 2500HD 6.0L, regular cab, long bed, 5 speed.... ive pretty much made up my mind on a flowmaster muffler, but my question is too whether run it out the side just before the rear tire or run it straight out the back... i like the look and idea of less work of running it out the side but have seen different opinions saying it made the performance of the motor go to s***.... just looking for some help on deciding what to do

 

I like it running out the side myself.
I have true dual 40 series, very nice sounding.
I cant hear any "drone" sound others say they emmit

 

Out the side is a lot nicer if you do a lot of trailer towing.

 

I prefer turn-downs right out of the muffler I think it looks much cleaner and that way, but to each their own.

 

thanks guys, but how about performance, does goin out the side versus rear affect it at all??

 

nothing noticable.
essentially free-flowing straight out the back could potentially net you a miniscule ammount of power, but nothing noticable.

 

I would say the less bends the better, but as stated, it would not be anything noticeable.
