 Subject: Headers

Message:
About 1 year ago I bought a set of flowtech shorty (emission legal) headers and installed them on my 92 4x4 5.2L. After installing them I noticed no difference what so ever. I was wondering if just get rid of a bottleneck and allow other mods to perform better? Or should there have been a noticable difference?

Is this your only mod?? From what I have heard you would need other mods that wen along with the headers (Intake, throttle body, manifold, exhaust etc..) to really see the difference

I was talking to a guy at the track 2 weeks ago with an R/T and he had just swapped on a set of Flow-Tech headers , he slowed down .15 compared to the week before. From what I've heard the Mopar Performance headers are the only ones that make a real difference.

The biggest restriction is the Y pipe.
MP headers replace the Y pipe. My MP headers are great!

Your stock setup (from your Flowtechs) is the major restriction. You could have gone with Doug Thorley headers (mopar). They replace the Y-pipe. Your stock manifolds were a higher flow than the Flowtechs ('92-93 Dakotas were rated at 230 hp, using a LARGER exhaust manifold than '94-97).

My PPH headers (along with replacing the entire exhaust) made a huge difference in acceleration.

You should be able to have a GOOD exhaust shop set you up with a better Y-pipe configuration, and that will improve everything.

Will they have to goto a smaller pipe so they can get it to fit? My y-pipe is 2.5" i think and in some spots it is almost completly flat. If they have to goto a smaller pipe will this still make a difference or can they keep it the same size and still bend it better?

Do you have skid plates?? If so.. you might be stuck with what you have. An aftermarket/custom Y pipe might not clear your skid plates (that's the reason behind the crimped X-over pipe.) Otherwise, if you don't have skid plates, a good exhaust shop should be able to form fit you a better configuration (Y pipe) in 2.5". The Doug Thorley setup will not fit (from my what I remember) under the skid plates. This is also true for newer ('97 up) 4x4 w/5.2L I went with PPH for my '99, and it hangs down a bit (nothing major, still higher than the front front end/frame).
