Headers

[revgrizzly91]

Anyone got a source for aftermarket tube headers for the 3L V6? Does a X pipe give better flow as compared to an H pipe? Are dual exhausts a waste?

In a nutshell H pipes are louder, and give more low end torque, and x pipes give you more high end horsepower.

 

But I'm pretty sure nobody makes longtubes for the pathy's that dont go into a y pipe...which is not true dual exhaust, which makes an x or h pipe not an option.

so...are shorty headers available, just lookin' for more flow in the exhaust and thought dual would be the way to go. Any suggestions?

thorley & pacesetter make headers for pathys, as far as true duals, just go with a single exhaust with larger piping, the benefits of true duals on a V6 is slim to none and really not worth the time & effort.

yup. what pavelow said. x and h pipe are more for your chevy v-8 apps... just go with thorleys, 2.5" pipe throughout, high flow cat and a good quality muffler. and use the search function, there has been a LOT of discussion about headers, pipe, and there is even some sound bytes of exhausts (including mine) int he pics/vids thread

I put some Thorleys on my 'finder. Man do they make a difference. The finish on them is quite up to par. Hell they still look brand new to this day, and they have been in there almost two years! I went with Three inch exhaust from the headers to the cat and then squeezed it down to 2.5" for the Borla system. As for the Borlas, Im not that impressed. I think you can do better with a different brand or setup one yourself. I notice that if I have the truck loaded up the exhaust bangs ont the undercarrage alot.

So for me, I would go with the Thorleys.

PS - The exhaust shop in Denver told me that emission laws allowed removal of one of the Pathys cats so now I have one large 3" high flow cat!

Thanks alot, saved me from a hit or miss install...I was leanin' on a bigger single, but thought the dual would look trick. Thorely's it is...cheers, lads!
