Im geting new exhaust for my 6 this month and im trying to decide if i should get True dual welded behind the stock cats or dual h pipe welded from the stock cats ,And im geting flow master 40 series with 3inch tips .

Iv heard true dual helps on the back pressure witch helps on low rpm horse's and i also think true dual sounds better but whats your opinions h Pipe or true dual ?

H pipe IMO with high flow cats, but go on you tube and listen to see what you like best

H-pipe, deleted two of four cats, and s-flow resonators

Oh, I also didn't really notice a difference in low end torque really but it does feel much better up higher in the rpms

H pipe no cats and 40's and call it a day

Go with whatever is cheaper. Both will yield the same results on a stock car.

I personally did the true duals with the H-Pipe and have never questioned my decision since I made it. So obviously I would recommend it. Good luck on your decision.

power wise you are correct, sound will be different though

I just recently had my 2006 mustang v6 exhaust system Y'ed off into duals and I love the new sound and feel. Combine that with a nice aftermarket exhaust and you'll be satisfied for a while.

Whatever you decide you put on make sure it'll pass smog too.
