Ok,i just installed a Roush M90 on my 08' Gt. It runs really well but before i purchased the M90 i got a set of Kooks LT's & catted x-pipe but never put them on.My question to everyone is if you guys think it is worth going through the trouble of installing the LT's & x-pipe? dont know how much of a hp gain i would get? please let me know if you have any info or suggestions! i can get a tune for the LT's if i need to so thats not a big deal. Thanks

First u will need to make sure that the cats that u have are metallic or ceramic. Ceramic will melt then clog and then blow your engine. Metallic are made to handle superchargers.

Then who ever u have tune your setup make sure they are reputable.

I will check on the cats to see what the insides are made of. I bought a SCT Tuner from American Muscle w/Bama tunes doing tuning. Dont know much about them cuz before i could use the tuner i put on the Supercharger & Roush did the tuning.U know much about the tuning from Bama/American Muscle? Thanks for the response!!

I havent dealt with bama tunes but i hear people are happy with them. I deal with brenspeed so its a choice and everyone here makes one. Either way u wont be disappointed

Im pretty sure the kooks catted X has metallic cats. have seen alot of guys with FI running them.

bama wont tune for FI cars to my knowledge. You will need to go through JDM or VMP for a tune on a FI car, especialyl roush. i looked aroudn a lot and settled on VMP.

with the 500hp kit and the LTs, you should be right at 450whp with a 93 oct. tune

Thanks,i just checked with Kooks & they said i should just have it dyno tuned once i put the headers & catted x on. the cats are metallic but Kooks said that the two year warranty wil be void if they blow due to the tune. i will have to check into tunes & see where to go.this s$@# sure is getting complicated!!!

You were rite on,Kooks are metallic so thats one less thing to wori about!! Now just to get them on & get the tune!!!

Stupid question but im in Colorado & we only have 91 octane! Do you think that they change the tune to 91 ctane from 93 octane? i always hear about 93 octane tunes but no 91 tunes! Any input on this topic?? Thanks
