hey i bought my 03 gt a little while ago and im undecided between the Magnaflow Magnapacks and the SLP Loudmouth. i know the loudmouth is more agressive but im worried about which one has more gains in power. if anybody with either of these can let me know the power they've gained that would be awesome cause i would love to get the loudmouth but am concerned it is just a noisemaker without power thanks

 

well nevermind, bought the magnapacks

 

Good choice....I would say SLP and Magnaflow are probably the best performers out of the bunch....they both sound good, but I prefer the magnapacks!

 

Good choice, magnapacks actually have a tone, and are better quality, have fun with the packs

 

Hi, I have a 2001 Gt convertable, I just bought the SLP X-pipe (23008) and the Magnaflow catback (99003) today. This was what Bob ( a tech ) from Mustangtuning.com reccomended. I will have it done as soon as I reeive them. I will let you know. I was also unsure about the Magnapack, but due to the convertable, I went with the 99003

 

damn you would of loved the sound of the packs i have them and damn! they sound good. the other day i had my brother dive by with my car so that i could hear them and wow! its sad that i didnt know how my car sounded on a drive by with the packs especially since i have had them for 2 years. anyways i just cant wait till i finish the exhaust set up.

 

i think im gona go with the BBK H-pipe and BBK full length headers

 

Go with the MAC Prochamber for mid pipe

 

:stupid:

 

The Magnaflow Tru X will really wake it up.It did mine and I have the catted X!!
