Alright I Am Fixing To Put True Duals On My Truck And I Was Wondering If They Will Be Able To Run Each Side Of The Exhaust Down Each Side Of The Truck Or If They Are Going To Have To Put Them Both Down The Same Side, And If They Do Have To Put It Down One Side Will It Hurt The Performance If One Side Of The Exhaust Has A Lot Longer Piping Coming From The Header Going To The X Pipe.
I Have An O4 Gmc Sierra Rcsb Z71. I Am Putting Asm Headers, Into High Flow Cats, Into A Magnaflow X Pipe, Into Dual Dynomax Bullets. Please Help!

 

I have a feeling you are going to want to put this in one of the truck subforums on here...most of us won't know what you are asking.
