MAC o/r H vs. MAC Prochamber....
 

Ok so I've got the SLP o/r x and LM1. I'm lookin for something different and a tad quieter. I wanna keep the catback or possibly switch to the LM2 but I can't decide on either the MAC o/r H or Prochamber. Has anyone heard, in person, the o/r h or prochamber with LM1 or LM2's? And what kinda sound difference is there between the o/r h and prochamber? Just hopin someone can help me out.

Well the prochamber is quieter then a o/r h.

If you are looking for quieter then dont get the o/r H.

Ive heard a pro with a LM 2 and it sounded real good

get the loudmouth 2's ..theyre quieter and a have a lil more tone

i say go with LM2 aswell, this weekend i just swapped out my LoudMouths for LM2s and O/R H with an O/R X and dayum it sounds good!...reminds me of the stock H+LoudMouths but alot louder,im diggin it!! ill try and get a soundclip later on in the week for ya!

please doo!!! haha

I assume the o/r h would be as loud with the lm1's just as with the o/r x, but with a deeper tone. I don't mind it being somewhat loud but at 2500 rpms, it's too loud. I think I might go with o/r h and lm2's. What ya guys think?

Yeah I wanna hear the sound of it. What kinda o/r x you running with?

Might as well try the O/R h with the lm1 and if its too loud get the 2

I have the 1 with a mac o/r h..but I love it loud as hell

Does it have an annoying loud pitch around 2500 rpms or so? It kinda sounds like it has no tone at all like blaahhhhhhhh.

im running with a UPR O/R X with LM2.....and i wouldnt run LM2 with an O/R H,sounds too much like glasspacks too much blatt...check it out....

..and yes the O/R H and LM Is will have that high pitch at 2500rpms,fooking LOUD!...i loved it but lost too much backpressure with that setup,causing my car to be alot slower or atleast it felt that way!!

Yeah I could tell the same about losing backpressure, but my top end improved. The lower end lost some power but when it gets around 3000 rpms, it takes off like no other.

true^....this isnt my car but mine sounds very similar....mine still need to break in a little more,but its definately getting louder,check it out!

Sounds pretty good. How much quieter is the lm2 than the lm1? I don't want it to make it too quiet. I still like it loud but I want something that'll get rid of that blat at 2500 rpms...or at least tone it down a bit. By the way, what song is that playing during the vid? I can't think of it for the life of me.

Here is my car. I have an O/R prochamber and SLP LMII. It's an in car video, but you can get a sense of what it sounds like. http://videos.streetfire.net/search/...570167ca93.htm

being a newb im a lil foggy on all these abbreviations

what is "UPR O/R X with LM2"

listened to the clip and that thing sounds awesome

UPR is a brand
O/R x means an off road x midpipe
and LM2 is the slp loudmouth 2 exhaust

i wont lie to ya,the LM2 are alot quieter than the LoudMouths,and i had the same setup as you Mac O/R H+LM but i do like it alot more,the tone is just awesome!!..but for you if want to tone it down a bit i say get a catted X or catted H..heres Ghost Riders vid with a catted H,still loud but not too much blat or poppiness...http://youtube.com/watch?v=Mq5kTcq0CDw

ohh and that song on the LM2 video is Disturbed-Down With The Sickness

Now that sounds pretty good in my opinion. So he's got a catted H with lm1's or lm2's?? Did he ever have it without cats? If it's a catted H with lm1's then I think that's the route I'm going.

i went throught the same dilema that you guys went through and now i have a mac h with a stainless mac catback. i liked the loudness of the slp's but it was too raspy on decel. i am very happy with the mac setup and its deep loud and raspy at the same time. if you want deep go with a prochmaber if you dont like it it after that then try a different muffler. by the way i am 18 and love my mustang loud but it just didnt have that much tone before i got the mac.

I've had both. Go with the prochamber. Or something with cats to be quieter. THe H Screams with my magnapacks.
