I have a 97 gt with stock headers, off road x pipe and 2 chamber flowmasters, i was thinkign about getting a slp lm1 setup. Compared the my flows right now will the slp lm1 be noticably louder than the flowmasters

SLP is too rich for my blood.

I havent installed my LM1s yet but I can almost guarntee you it will be louder. I got flows on my 98 GT when I had it, it gave it a better tone IMO but wasnt even really much louder than stock. The LM1s are the loudest mufflers on the market I believe. I have heard to stay away from O/R Midpipes with them however. Supposedly an X pipe will give you less deep of a sound compared to an H pipe, but its all about preference.

with that o/r x-pipe its going to be crazy loud, i've heard it and its much too loud for my liking. but if LOUD is what your looking for... LM1's + o/r X would be good for you

IMO....SLP is the wrong kind of loud....[:'(]

+1! There may be others who disagree with us but you loose a lot of sound quality w/ the LM1. And it's not even a question if it'll be noticably louder. It'll be insanley loud. My buddy has the LM1's on his GT. The only time I like it is when he's getting on it, makes your ears ring. But i would never own that set up, I think sound quality is more important than loudness...

I have LM1s with a bassani off road x pipe. I love it, my friends say its way too loud for the street. I like to drive my car and not be able to talk inside though.lol I love it.

You guys got it all wrong.

I had LM1's on my Stang w/ headers and a CATTED H-pipe. Nanaki and I have been saying it forever.

If you have a CATTED mid-pipe, go LM1
If you have an O/R mid-pipe, go LM2

The H-pipe is the way to go with the LM series. I think an O/R pipe with LM1's sounds like shaz, too loud, raspy, pops too much, etc.

I can honestly say after all my exhaust combos:

StockH: Stock catback, Flowmaster Catback, magnaflow catback

Magnaflow X: Flowmaster catback, magnaflow catback

Mac H: Magnaflow catback, SLP LM1 catback.

The Mac catted H/ SLP LM1 catback is the best I've had.

With the Magnaflow X and Flowmaster catback, how would you describe the sound?

Was the Magnaflow X catted or O/R?

I'm looking for a midpipe to go with my Flowmaster catback (bought the car used with catback on and someone has told me it was Flowmaster but not sure) but I don't want loud, just want some performance. Is that an oxymoron?
