RetroGT2006

Hey guys Currently my 2006 Mustang GT has a JLT II Intake, Tune, FRPP 3.73s and Flowmaster American Thunder Axelbacks. It is lowered on FRPP K-Springs(1.5in all around).

I was looking at purchasing Longtubes for my 21st birthday in October(21st). I have narrowed it down to two setups.

Kooks LT Headers + Catted H from brenspeed(stainless steel) $1359.00

or

MAC LT Ceramic Headers + O/R Prochamber $860

I want opinions, but from people that have had either of them or know somebody that has personally. I want to do this ONCE, so i do not want to cheap out and buy something due to price. Somebody point me in the right direction.

Are the hp/tq relatively close to each other or exactly the same?

Which would sound best with my Flowmasters? I know i know, the Flowmasters sound horrible with alot of other setups. I do NOT want to replace them right now due to money.

well as far as power, ive heard that the x pipe increases hp more than the h pipe but the h pipe increases tq more than the x pipe. ive heard a few mustangs with the h setup, and they sound like a beast. i personally went with the dynatech longtubes with a catless dynatech x pipe. i have a magnaflow catback... power increases between brands of pipes, i wouldnt be too worried about. i think it would be a small difference. its more the sound for me... youtube some setups. there are plenty of videos. my friend with an 06 GT has the flowmasters with dynatech lt's and a catted x pipe. it sounds very good. here is a link to my setup... http://www.youtube.com/watch?v=Eo7SXio2Qf8

Sweet sounding ride bro! Thanks on the info and what not- i am really surprised that you were the only one to reply lol. I just got home from work thinking id see more responses.

I can not wait to add my LT's.

Regardless of what combo you have the LT's will smooth out the sound and maybe make it louder depending on the rest of the setup.....the vid sounds great!

damn, that's one of the best sounding exhaust systems I have heard (with mufflers)

Id go with mac bro, cheaper and just as good and o/r prochamber is better then a h IMO.

save mone when you can and with that been said the extra money you saved on the mac set up you could get diff mufflers lol

LOL true that, i was thinking if i went with new mufflers- it would be Pypes Mid Mufflers or Borla stingers. Leaning towards Pypes MM's because my neighbor has um and they sound sick and they are less $..

Will you still pass emitions with the LTH's? I live in AZ where they just hook up to the computer port to check your car, no visual inspection that I know.

From what i hear, any LT headers are illegal and you will NOT pass emissions. Luckily florida does not have any tests..
