SLP on 03 GT
My brother just got done a couple days ago installing the SLP loudmouth exhaust on his 03 GT. The onlyy other mod he has is a K&N CAI. Let me be the first to say this beast sounds good. It's sounds better than straight pipes and reminds you of a 60's Mustang with the popping and backfiring growls it makes as you rev it up. It's the exhaust I'm buying next month for my car as well. Do any of you guys have SLP on your cars?

I'm putting the SLP catback on my cobra later today along with a MRT h-pipe. I'll let you know how the install goes and how it sounds. It should be a lot different from the absolutely quiet stock exhaust.

RE: SLP on 03 GT
I just had an MRT h-pipe and SLP catback installed on my '04 cobra. Calling it loud wouldn't do it justice. It sounds great when at idle and at part throttle but flooring it lets out some kind of hellish wale. I've had flows and dynomax on my '88 5.0 before but I've never heard anything like this. Don't get me wrong. I wanted loud and got it. But the only thing I could compare to this was when I went to the nascar race here in vegas. This car just sounds mean. Luckily, it's not my daily driver but when I want to scare someone on the street all I'll have to do is blip the throttle and give someone a heart attack.

RE: SLP on 03 GT
I know what they sound like on an LT1 and an LS1, I have one on my car. it;s mean as all get out. Nothing compares to it. I had a guy in a 99GT ask me what kind of headers I had, which I don't just have stock manifolds. I have to say (and this is rare for me so enjoy it) That the Mustangs have always had a better, cleaner, smoother sound then the 4th gen fbodys and I would really like to hear the Loudmouth on one.
