FreeFlow Stock Exhaust, or TurboBack??

[richc22a]

I have had studs installed, tunes, and on a weekend home gave a colostomy to the kitty, cut off the muffler..opened up the stock exhaust as much as possible (( love the way it sounds (Looney)) but wondering what diffence a turbo back kit would make? Any experienced words of wisdom from the gurus who reside in the vast knowledge base here???!!!

You will see a few HP gain from a turbo back system. but IMO, the real incentive comes from lower egt's and bit less turbo lag. I'm not sure how the later 6.0s are but the stock downpipe on the early 6.ohs is horribly pinched down.

The biggest factor will be lower egt's with a 4 inch straight pipe exhaust. You may see a little more hp but not much.

Put a stock down pipe next to like a Magnaflow 4inch and you'll see the difference.........
