Hey i'm new at this guys and i just joined so i just have a few ?'s and wondering if someone could help me out with this

Right now i have a 06 f-150 5.4 with roush air intake and flowmaster 40's SI/DO

and my ? is within the next few months i wanna get a new exhaust manifold put onto the truck and i really like the dynatech exhaust manifold so really i just wanna know how much louder is it going to make my truck and what do you guys think about the manifold?

 

NEVER heard of them...
I've heard great reviews on the JBA headers tho!!!

It'll be louder how much I'm not sure...
Anyone got a sound clip for the newbie??

 

I like them alot.. i wish i had the 5.4 in my 98 so i could have gotten them.. if im not mistaken (again) dynatech is the best for the 5.4's as long as ur talking about long tube headers and not shortys...manifolds are usually refering to factory/OEM... Troyer Performance has them but not sure for the 04 up but its possible check out TroyerPerformance.com.. look around for the best price tho.. and long tube headers will in deed make any truck louder, especially with the hi flow cats which is offered on the headers from dynatech.. they r jsut very pricey which is why many people go with pacesetter or shortys.. hope that helps.. TIM

 

The pacesetter long tubes are much much cheaper and will perform just as well, if you want it to sound good get rid of the flowmaster and run true duals with some magnaflow mufflers

 

ya i was talking about getting the longtube headers cus i know dynatech has the whole set hi flo cats, longtube headers, and a y pipe

 

If you are goin to get longtubes, don't run them through a y-pipe, run true duals. A y-pipe is very restrictive.
