American Racing Headers... H Pipe Option
#124
I will be S/C'd when these go on which is why I am going with the 1 3/4 ... so sounds like I will continue to wait for the H pipe!
are you really worried even if it was say 10hp? i guess if your N/A 10hp would be huge. youll prolly see close to 10 on a S/C car but N/A will be 2-5hp tops. and even if it was 10hp, unless your a dyno queen you will never notice a difference between 300hp and 310hp realistically.

CR, I do have a question. If I were to eventually get my car S/C'ed (but not for a while), and want a set of these, will it hurt to run the 1 3/4" pipes on a non S/C'ed motor. Also what would happen if you were to put the 1 5/8" pipes on a S/C'ed car? Thanks for the help.

Go with the 1.75" if you're going SC down the road. We can tune it out for the time being. And being local we can put you on the dyno and get it exactly right... no mail order closeness, dead on!
As for that price (under 1400), yes that was catted. The noncatted will be well under 1200 dollars. I will have exact pricing here, soon.

SWEET!!!! I am really digging this mod!!! Hey CR, I currently don't have a tune on my Airaid. I was going to wait to get one from Doug, once I decided if I was or wasn't going L/T. What is needed to get the car to run right with these? Is it anything major? Thanks again. ![Thumb](https://themustangsource.com/forums/images/smilies/thumb.gif)

I'll tell you what... if you go with the headers, we'll set you up with 3 tunes for 100. They will be exact. We're going to need to do some work with the MAF transfer and borderline knock table. We'll throw you up on the dyno, and get the tune exactly right, and be able to show the HP gains with the LT's.

Hey CR am I missing something here. I thought it was the other way around. I thought 1.34" were recommended for SC applications and the 1.75"s were for N/A???
Go with the 1.75" if you're going SC down the road. We can tune it out for the time being. And being local we can put you on the dyno and get it exactly right... no mail order closeness, dead on!

The 1 5/8" are still VERY nice headers, and reccommended for those who are not looking to go FI down the road, or have any other mods that would justify 1 3/4" such as cams, nitrous, etc.
The 1 3/4" is only like 20-25 dollars more than 1 5/8", so it's definetly worth the investment!

****....this is what I get for trying to work and fish for mods at the same time. After looking at what I stated I was like duh, yes 1 3/4 and 1.75 are exactly the same and that's what I'm looking for as I'm looking to add a supercharger this summer. Ok.....now back to the group buy question, is one going to be setup???
1.75" = 1 3/4" They are reccommended for supercharged applications. Even if you don't have an SC and you're looking to SC down the road, the 1 3/4 (1.75) will still work great until then!
The 1 5/8" are still VERY nice headers, and reccommended for those who are not looking to go FI down the road, or have any other mods that would justify 1 3/4" such as cams, nitrous, etc.

CR, that offer you posted, 3 tunes for $100. If I have an X-Cal from Doug, can you load them into it?
