okay so yesterday i put my stock muffler back on because i couldnt stand the DOD drone in the cab. i have the dynatech longtubes with the highflow cats, it seems noticeably different in power, should i get a retune with this or a better flowing muffler? or is the stock muffler good flow. (the muffler came off of an 06 and had a flowmaster 50 series on it)

 

If your after power get rid of that stock muffler, it's a. Huge restriction

 

get dod turned out in the tune and put a good muffler back on

 

Yea, put on a good flowing muffler and Rock & Roll....

 

awesome that sounds like a plan then, i just couldnt stand that on all the damn time it was annoying, just need to sell the rims now. then i can get it taken care of
