...do you notice any difference in sound? I was wondering, because I am thinking of getting a pair. I have the FRPP GTA axleback mufflers, and I just wanted a little more sound, and I don't want to change the axlebacks to anything else, or modify the stock exhaust outside of the shorty headers. I know performance is negligble with them, and I don't want long tubes. I was just wondering if the sound changes at all...?!

Yes the sound does change, it gets a little deeper, but not louder IMO. I don;t have them myself but I've heard another member's '05 with Flowmasters before and after the JBA shorties.

how about changin midpipe also to o/r h pipe

Would shorties give any more power with a SC? I know everyone says they don't do anything on a naturally aspirated motor.

Caution

I'm N/A with shorties and my numbers are decent... see my sig. The O/R H will make your stang louder/ deeper ... the O/R X will make it louder/ raspier and typically a 3 RWHP gain... I would think with an SC it should gain you something but at that point I would just go LT

Since our stock manifolds have a header like design from the factory I was thinking of getting shorty headers (304 SS) for the looks as I cannot stand the surface rust on stock ones. Not interested in LT's either butI am glad to hear that it may give a deeper sound to the exhaust note with the shorties. My exhaust is loud and deep with some popping sounds from time to time but after the S/C install the sound changed andI lost a little of the deep resonating tone thatI had before. I assume it is because the car is breathing deeper now hence more compression. Took some getting used to but I still love my magnaflows and side exhaust.

Moose -if you can find a 1 3/4 inch shorty header you will get rid of the exhaust gases quicker and have a cooler overall under hood and motor temps. I know you know this butI cannot find (have not looked hard) anything other than the 1 5/8 inch shorty header made by C.A.M. on Ebay. I do not want JBA as they use 409 SS andI want 304 SS. Besides I am happy with 454 RWHP now and not interested in small gains with an expensive LT header and difficult install.

Jason, the shorties will look real good, every Mustang owner that looks under my hood comments on how nice the headers look.......

Of those of you that have the shorties, how many of you installed yourself and could you do the install with out a lift or cherry picker?

Thanks guys, I think I will go with the shorties, I am just looking for some subtle sound change, and a nice look under the hood, nothing else as far as gains in HP are concerned.
