SLP loudmouths?

fasterv6 · June 25th, 2009, 08:18 PM

hey guys sorry about another exhaust thread, but im looking for a setup. i saw a video on youtube of a guy with a sixxer with a pacesetter o/r h pipe and a SLP loudmouth 1 system for a mustang GT, does anybody have this setup? im looking for something with a deep sound to wake up my neighbors

mooses · June 25th, 2009, 08:37 PM

imo, SLP sounds like ass on our cars.

04mustang232 · June 25th, 2009, 09:08 PM

nothing will really get you a deep "wake up the neighbors" sound.

If your motor is stock, a simple catback will sound the best. See the exhaust thread for clips.

However, mac lt's, offroad h pipe, and slps will sound so loud and raspy (and shitty), im sure your neighbors will hear it.

slp is loud...but they dont sound right since we only have 6 cylinders

ive talked to some of the people on youtube with them, and they say it sounds good at idle, but they dont like it at wot.

yellowstang6r · June 25th, 2009, 09:23 PM

I'm with ya man. I love they way they sound but never heard them on a 6. I dont really know the differences between the LM1 and LM2.

white03v6 · June 25th, 2009, 09:37 PM

ya ive never understood the LM1/LM2 difference either

SLP loudmouth mufflers 1 are louder cuz of the resonators, 2's are kinda quiet....

fasterv6 · June 26th, 2009, 03:28 PM

well do you have any other suggestions? because i kinda like the raspy sounds but i want it to still sound good at wot, i saw a vid of SLP's on a sixxer on youtube and it sounded pretty good, but that could just be the video...

2002 BLK GT · June 26th, 2009, 04:47 PM

Mac with an x pipe in my opinion but if you liked slp go with it, its what you like not what we like......

yeah good point
just wanted to get other peoples opinions haha
im on a pretty low budget so i dont wanna screw anything up

punisherstang · July 2nd, 2009, 05:51 PM

from personal experience with my 01 gt dont go slps, the slp 1 mufflers are just a bullet style straight through straightpipe, the slp 2 mufflers are your basic muffler an are a little more aggresive then magnaflow. i had frpp shorty headers, magnaflow CATTED xpipe an slp1 an it sounded good but was still pretty loud, then i switched to hooker longtubes w matching o.r xpipe an it sounded crazy stupid loud, gave me headaches all the time, an i could set off car alarms when i wasnt even close to a car yet. i know this is my experience with my gt but honestly a sixer requires a deep tone muffler, something like mac flowpaths, or force pro mufflers. and it all depends on the rest of your exhaust, if you go longtubes your gunna have to get an offroad pipe unless you get cats welded in. if you would get an aggresive muffler such as flowmaster american thunders then it will be raspy as hell an not sound too good(buddy has mac lts, or xpipe, american thunder cb thats how i knw). sorry for my speeel but hope it helps an take a minute when you have time an just search for diffrent sound clips on youtube before you make an exhaust purchase thats what i do. hope i helped a little

i wouldn't do any exhaust on a 6 er unless you eventually plan to go v8 anyways. will sound like ass. definately dont do something like an SLP exhaust either.

3-definately dont do something like an SLP exhaust either.

1-If youre going to get a V8 (especially if youre going to trade in the V6 for the V8), only spend money of the V6 if you have to. This includes maintenance/any repairs you may need to make.

2-Divorced duals with Thrush Welded disagrees with you

3-That was good advice

04mustang232 · July 2nd, 2009, 09:31 PM

Ive said it before and ill say it again, buying a 250 dollar mac catback IMO is your best bet. It sounds real nice, conservative, not raspy. And after a year of driving, it gets broken in and starts to baffle a lil. I get compliments on mine ever once in awhile and im really glad i didn't get lts and/or h pipe.

how bout a 3 inch wide downpipe with a magnaflow at the end

as long as you have a turbo bolted/welded to the other end of that 3 inch downpipe woody, i think you have a point.

GreenFaleen · July 3rd, 2009, 12:18 PM
