I myself just about **** my pants, when I won the bid on ebay for my GTP. I looked at my wife and said holy smokes nobody else bid babe. She was really happy it's a 2dr like she wanted and had super low miles for a 1998. She really doesn't drive it often as I thought she would. She likes her Mazda6, it's got the 220hp engine.

Also what type of downpipe do you run with the headers or is it totally eliminated? I want to get the cat converter off the car, I live in Ohio and we have no emissions. All they do is choke the car anyways.
I can get some engine bay pics up soon. They come with a 3 inch catless DP and they look awesome. I've got a cheap $40 ebay intake, drilled 180 t-stat, autolite 104's and I ported my blower outlet myself. I'm running no knock on a 3.3 and I'm sure I could run a 3.2 or 3.1 with minimal or no knock. There is no point in buying expensive zzp/ slp headers unlless you're trying to dig into LOW 12's or 11's, and by then, you'd be better off going turbo. Here are pics of them on my living room floor fresh out the box.


You can get these with a VS cam, pulley valve springs and all the supporting mods plus a GREAT TUNE and run a low 13 for less than 1700 bucks installed if you don't mind traveling to Michigan. PM me if you're intrested
