I have an '06 GT and I just got my H-Pipes from Summit Racing. Does your check engine light come on without the Cats since you put the H-Pipe on?

@CaptAvenger2004 It more than likely would have but I have the rear O2 sensors turned off in the tune. You can do this by buying a handheld tuner or buying MIL Eliminators.

how do you like the sct flash tuner? im considering getting one for my mach 1..

thanks

@jamesleeland

It is alright. It is a slight power increase but nothing too noticeable. It all depends who does the tune on it. Its worth having if you ever have your car dyno tuned. I bought it because I can use it to turn off the rear o2s and its also worth having, just don't expect it to be a big power upgrade. For what it is, I like it though.

stock headers? What kind of rims?

[mxt2s]

@ChrisXCXCX Yep stock manifolds. 18x10 Saleen rims on the back, 18x9 Saleen rims on the front.

that sounds sick i am buying an 88 5.0 and im not sure what to put on it i know its not gonna sound like yours but i would like a tip or two im 18 and just entering the world of stangs

@Patron1520 is that on a cold start or when its hot? it shouldnt be idling that high when warm. i idle at 650-800 rpm when warm. could be a maf mapping error.

Do you know what series 40 you have? Does it drone inside tbe car bad? I have a 1991 that I am thinking of putting flowmasters on.

[Peek82454201]

nice progress you made with the exhaust.

[Patron1520]

My stang idles at 1,100Rpm. Thought it was kinda high but yours is the same. Btw it sounds sick.
