WHat is the best header on the market?
Mike, I always give my honest opinion, no B.S. here! And that is sometimes embarrassing because I have screwed up and put the wrong damn parts on my car from time to time.
The XR1 I used is the Oval Offset, not the round one that looks like a bullet muffler. It's straight through, but still amazingly quiet, at light throttle. Once you put your foot in it, it's loud, but that's what I like about it, you have control over it. At idle and light throttle, it's much quieter than the Loud Mouth with stock cats, and no drone or rasp (but still louder than stock.) At WOT, it sounds much like the LM without cats, only not quite that loud and raspy. Kinda NASCAR like sound . . . It's more throttle dependant than rpm dependant; makes a nice racket even at 2300 rpm but only if you have your foot in it!
I sawed my LM resonator in half with a cop saw and used the two pieces as 4 inch to 3 inch and 3 inch to 4 inch adapters, hence "BorlaMouth." I couldn't afford the QTP Y pipe, so I modifed the SLP Y to fit the QTP headers by cutting the end connectors off and spreading it wider with a hydrallic ram . . . this is a temporary measure until I get a real 4 inch system.
I think you will like the Borla XR1 Oval, but it's expensive. I screwed up and ordered it direct from Borla because I got in a big damn rush, but latter discovered Jegg's had it for a much better price.

The Y pipe acts as the interface between the catback and the rest of the system. So normally you get a Y from the header manufacture. All of the Y's have their output in close to the same place.
As i was saying before in another post i am getting the flp system for 700 bucks slightly used, do you guys think i should still stick with that for the money? and i heard someone say something about them rusting, waht is the deal with that? and how is the fit with the flps, do i need to fab anything up?
