    rwhp gains with duals

    I'm heads,cam,intake and put down 417rwhp 407rwt in an A4. I'm wanting a little more rwhp.I know i could go with bigger cam from my tr224,but it would have to be alot bigger to justify the gains and labor cost for the swap,and i would lose low end power and have to spin it to the moon just to gain.So is anyone out there with H/C/I that just switch from an ory LT set up to duals? Did you strap it to the dyno and what did it gain? I'm more interested in gains than sound.I'm pretty happy with the way it sound with lt ory and dynomouth just want a little more N/A rwhp.Second question I have Hedman lt hedders does anyone know if the make an x pipe for these hedders,or would i have to do a custom x pipe
    thanks

    I read the sticky,but it does not say how much rwhp is to be gained it just says some gains

    Forget about peak hp with duals, it's the under the curve power that takes a noticeable jump with them. I've seen members gain as much as 12-15 hp in the 3000-5000 range with TD setups.That's where the X-Pipe setup helps out

    I have true duals going over the axle and out the back. I used the stock manifolds and stock catalytic convertors, an "H" pipe and straight through, noise cancelling mufflers and I picked up 15 RWHP.
