SLP Loudmouth I or II? Help! - Camaro5 Chevy Camaro Forum / Camaro ZL1, SS and V6 Forums

jaeatmon · 09-11-2013, 09:43 PM

I've decided on getting the slp loudmouth exhuast on my 2012 v6 camaro, however I'm unsure if I want the 1 or 2? Can someone explain the differences and what you would reccomend? I chose the loudmouth because it sounds best at startup and revving it, but how does it sound at high rpms?
I previously had the mrt axleback v2 on my old camaro. How does the loudmouth compare?

From what I understand the loudmouth 2 is a quieter version of the 1st one. The first one is much louder and also much raspier.

The loudmouth is essentially a muffler delete which is something you could get done for 100 bucks at any shop.

But if you are set on this exhaust: If you just want pure madness and the louder the better, get the first one. The second is not as loud but still very loud. I compare it to the difference between the MRT 1 and 2 but on steroids.

Oh and you're going to get plenty of drone with both exhausts, but more so from the loudmouth 1

While the loudmouth is louder, I (and many others) prefer the sound from the MRT exhaust. In my opinion getting the loudmouth would be a downgrade from the MRT.

LMII for sure. It's plenty loud and anymore would be frankly obnoxious due to the drone. If you want LOUD then do the MRT for sure. I truly enjoy my LMII though. Looks clean and i love the sound. It DOES drone though. Are you AT or MT?

+1 for MRT v2... I'm finally getting to the 1,000 mile break-in and sounds great!

+1 We still recommend the MRT and if you need something a little louder then the V2 you can always go with the V1. Also, removing the factory resonators is a easy way to get a couple extra decibels too.

The LM1 is essentially a muffler delete which I would never do on the V6 as it just won't sound good IMO. I would do the LM2 or the MRT V1 or V2 (Personally, I'd lean more toward the MRT V2) Let me know if you have any questions.

Best regards,

I have the auto transmission by the way. And is the mrt louder than the slp? I thought the slp was louder...

The slp is louder on its own... but the MRT sounds better. Add some headers or get creative and you can make the MRT as loud as the loudmouth and it will have that great sound too.

I don't think having an automatic transmission will make much difference with these exhausts.

LM are much more popular around here, I'd agree with this...

id say get the loudmouth 1 if you dont plan on getting any other mods like headers or a res/cat delete. The drone is kinda terrible and the car will be way too loud especially in small towns late at night, but I loved it.

I find that the AT SS is a lot quieter with the LMII. This IS a V6 thread, so nevermind lol!
