OK I'm going with a new cat-back system for my GT for Christmas and want to know what you guys opinions are on teh SLP Loudmouth system versus the MAC ssytem. I like loud, deep and aggressive, so if you have heard the two let me know which one you seemed to like more. O plan on going with a catted x pipe at some later point as well.

They're both loud but SLP is more obnoxious while MAC is deeper. With a catted aftermarket midpipe both will get you pulled over by the sound police. Best bet is to go listen for yourself at the local muscle car hangout or the track...can't go wrong with your own eardrums. Good luck!

I love the macs. its the second time ive put them on mone of my mustangs. They sound great and give you more of that muscle car tone. Plus they'll make your mustang sound alot different then everyone else with flows and magnapacks

You have all lost your minds. SLP provides better quality and performance right down to the tips >>>>>>>

slp owns mac when it comes to quality and the tips are soo much better. ive dealt with both. the pro chamber is nice. but it had tons of dings on it compared to the slp packaging.
if the loud mouth is to loud or you.... slp also has another series of mufflers coming out soon. (they may be available now, havent checked lately) keep your eyes and ears open for those to hit the streets soon.

SLP quality and sounds is awesome over anything MAC produces. Just ordered a SLP catted x from neweraperformance.com for $399.00 shipped! Will be getting the loudmouth catback to match soon also!
I just hope it's not as loud as some of you have mentioned.

If you want obnoxiously loud go with the SLP. In my opinion SLP just sounds like **** but if you want something that is really really loud get the SLP. If you want something that sounds like an old muslce car go with the MAC. As far as tips who gives a **** if you want nice looking tips just go chrome the tips of whatever exhaust you buy and there ya go. Quality I would say SLP is better quality but MAC is not as bad as everybody makes them out to be. I've never had any trouble with a MAC product.

Agreed! There isn't even a comparison here. I don't think anyone's even mentioned that SLP is stainless steel!
Now let's see - should I by a Yugo or a Cobra...which is better...?!?!?! DUH!
A nice setup would be SLP's (modular) catted X pipe (the cats can be easily swapped out with 'race pipes' which are just straight thru cat replacement pipes-save a few bucks and have a local muffler shop make these for ya) AND their midpipe also works with their long tube headers - this is a truly modular midpipe! Their catback is quality stuff and, ummm, well, how should I put it,...LOUD!!!!!!!!!

I'm in the same situation deciding between mac and slp. I've heard TONS of clips some just suck, some are good so I can't really go by them. I'm looking for scare women and children loud but still want the deep tone and mean idle. I was thinking slp with a prochamber? Anyone know how that sounds? What I dont want is anything that sounds like a tin can.

Macs are a chambered muffler so you get more of that deep muscle car sound,SLP is a striaght through design and has more raspiness.Like I said earlier Macs sound awsome and are more muscle car sounding then flows.
