Headers vs. Y-pipe

[r.german]

I have a 2006 hemi sport 5.7 and want to throw on some new headers. I was wondering whether or not my current Y-pipe would be defeating the purpose of putting headers on. I don't mind going full duals if it will make a difference performance wise. My only issue is that my ram is lowered a couple inches and the Y-pipe fits well. I don't know too much about mid pipes. Any help would be awesome. thanks.

If you are going with shorties, then I would "fix" your stock y-pipe. Me personally, I would go with a set of Pacesetter longtubes along with their 3" y-pipe. It is mandrel bent and slips right onto the Pacesetter collectors. Better performance, easy install, and its reasonably priced. The pacesetter longtubes are only $299 for painted or $429 for ceramic coated, and the Y-pipe is only $185. Thats not bad at all when you consider the gains you will see with them over the shorties.

Would that give better performance than true duals?

I dont see a need for true duals unless you plan to add ported heads and a bigger cam. Going with a well made Y-pipe is just as effecting and will move plenty of air for a truck with the basic bolton upgrades.

Thanks! I appreciate the input!

Any idea on the gains I would see? Right now all I have is a Flashpaq, CAI and flowmaster 40's

When I installed this setup on my 03 hemi, I gained 35hp/41tq from the headers and Superchips. I did not dyno them separate, so I cant tell you the exact power I saw from the headers alone. Reguardless, that is a substantial increase in power, and you will feel that power across the entire rpm band.

thanks a lot!

Matt, do u have to have custom tuning on the 4th gen trucks with long tubes?

 

[Hemi450hp]

You dont need custom tuning, but it does help to have some form of tuner. Back when I was real heavy into racing my 03, we didnt even have custom tuning as an option at the time. I was able to get my truck in the low 13's with basic boltons, a mild 6.1 cam, and a canned Superchips tuner. So while custom tuning will help you pull every last HP out of the motor, its not a necessity to run longtubes.
