I recently put edge w/attitude great mod on my 05 GMC next in line is an exhaust upgrade.this is where it gets fuzzy for me


aluminized vs 409 vs 309
single vs duals
catback vs turbo back
x brand vs y brand vs z brand
code eliminator........when do you need one
seems like the perverbial can o worms.
i know i want to lower egt and improve performance, along with improved sound, but what else is there to be gained or lost? is it worth the effort and expense?
I pull a travel trailer,alot, sometimes 800 miles plus.pull a boat and utility trailer,and i really like to see the look of some kid in a so called hot rod get waxed by a diesel 4x4 4 door truck love my ride but i think it could be a little better and i want to make it last at least untill its paid 4 so any and all input would be greatly apppreciated
