well recently i just oredered some long tube headers (pacesetters) from truckperformance.com and its for my 2005 chevy silverado 5.3L ext cab
my current mods are edelbrock shorty headers, aem intake, true dual dynomax bullets with an x pipe and custome dyno tune from synergy motorsports and it dynoed 300hp at the rear wheels and 316lbs of torque. my question is what would be the benefits from adding the long tubes on to my truck rather than sticking with my shorties. would my exhaust sound a lil bit rumbly or a lil bit louder. should i retune again

 

Yes and Yes!
You should pick up a bit of hp and tq with the swap.

Give us some new numbers after the swap too! Another Synergy truck! Have you run it at the track yet?

 

naw not yet man i dont have that much mods to make me wanna run it at the track yet. maybe by next month i should have the mods i want. TURBO AND CAM!

 

Get a good baseline and it's fun. There's always someone faster-no matter how fast you go, there's always somebody slower too!

The Long tubes were a waste of money if you go turbo. Now on a SC setup like mine.... I'm looking for a good used set!

I'm going back for October 25th. Be there!

 

why would the long tubes go to waste if im running a turbo? but im sitll not sure if imma go turbo. i hear good things about it then i hear the same thing for the supercharger nice truck by the way mine is exactly the same color n stuff

 

cuz unless ur doin a rear mount turbo the turbo goes in the hood and requires a custome manifold, hense gettin rid of the pretty LTs

 

o0o0o yea if im going to do a turbo its gonna be the sts rear mount one but yea im still debating it. turbo o super

 

You'll make a lot more with the turbo but I chose SC for fear of sucking H20 up that remote mount and also wanted to be CARB legal

Go turbo and we can line up! Good lookin truck BTW!

 

isnt the sts rear mount turbo carb legal? i was readin that is it

 

those are some pretty good dyno numbers for those mods on your 5.3
