In about a month I will be heading over to a local muffler shop to get a custom exhaust system made for my Tundra. I wanted to know what you guys thought would be an optimal setup for my 4.7L RCSB. Here's what I had in mind:

-Dual 2.25" piping (not sure what material yet :confused:)
-H-pipe
-Magnaflow or Borla mufflers (open to suggestions on that) with dual rear exit behind the passenger side tire

I'm thinking about leaving the cats out entirely or just getting hi-flow cats. I'm afraid that it might be too loud though.

My goal with this system is a nice, aggressive tone with a deep rumble at idle (I want to make my presence known :devil:) but nothing too loud. Low-end torque is a priority. What do you recommend?

Secondary Cat delete,true dual PowerSticks #22530SB(2.25X26")Classic Chambered Exhaust Inc. - Products (http://www.classicchambered.com/classic/products.html)
Dual right exit with 3" straight cut tips.
Aluminized steel will last you a good while in Fla.

FWIW You cant buy aftermarket cats that are any better then the stock ones you already have.
Your Sig references DT Headers ? they on there or not ?

Thanks. I was actually thinking about getting the Powersticks. I heard your truck and I liked the way it sounded.

Yes, my truck has the headers installed.

The 4.7 and 5.7 sound virtually identical,mufflers like the PowerSticks
will make you sound like you got a Big'un ;)

This style of muffler sure makes those little GM Vortec's sound sweet

I think I will be ordering the Powersticks then. But my biggest worry will be drone and noise level. I don't want my truck to sound obnoxious or drone loudly while cruising.

If low end torque is a priority, I would not run a dual setup. I reccomend having a y pipe made to instigate a scavaenging effect, with a 3" mid pipe into a Flowmaster or Spintech muffler with a single tailpipe. 2.5" for the most low end torque, 3" for mid range to top end HP.

Very Poor Advise.
There is no need for scavenging on a
DUAL VARIABLE VALVE TIMING IFORCE 4.7 or 5.7
Spintech and Blowmaster both droan pathetically :td:
