willl true duals makea hp gain like they do on a cmaro ls1 and will lt make a good diff? also what kinda intake is the best for the trucks??

 

You'll lose low and mid range power with true duals of 2.5" or greater. If you do them, 2.25" is plenty large on a 4.8 or 5.3

A solid quality catback and full length headers (The Other Guys, Arizona Speed and Marine, Bassani, Thorley, etc) would be fine with the y-pipe setup.

All the intakes do the same thing, allow more air in. I'd get which brand you prefer most...I got an FIPK as I got it for cost. That Volant is a nice piece, the UPD is too but cracks easily.

2¢

 

so i guess i should jst run a 2 chamber flow and be done with it..its not like a cmaro where id want off road y pipe or anything?? they have found on the camaro ls1 that runniin true dualls from header straight back is good..thats what i was wondering! i jst want my truck to sound really really mean

 

A Flowmaster won't gain much in the power area...I have a 40 Series and unbolted it to see how it'd run w/o it. It was noticably quicker with no muffler.

Hacking the cats may give a lil power gains, but not a ton by any means.

Don't forget Camaros haulass, our trucks don't stock. Their motors are larger and have bigger cams. To benefit from true duals, you'll need a cam that makes power well over 5500rpm and a stall converter to eliminate that deadspot you'd get with a big cam and a stock stall.

Is your truck totally stock now?
