Difference in SLP Exhausts

[Malan35]

Want to get my camaro sounding healthier so I am considering SLP Loudmouths as my first mod but can anyone tell me the difference between those and the LMII's and the powerflows? Is the I just a delete and the others are actual mufflers? And if I get the LMI's and later decided to do an x-pipe would that be very loud? I dont want too much drone but a little doesnt bother. I just really need that healthy V8 sound. I LOVE the sound of this car but does anyone know if there is a lot of drone with this mod?

Thanks for your help!

I see you like my Video lol. In that video I'm using the SLP 3 inch loudmouth 1 system. For me there is no drone with this setup. You will have a little with LM2 but not much. I also now have the proflows. The proflows hook with with the LM1 or LM2 and makes the whole system 3 inch. Check my my sig for that video. Right now I'm running proflows with no muffles and LM1, and I like it!

That vid sounds awesome! Haha i am the one who commented the other day asking all those questions. I cant believe there is no drone with the muffler delete on the proflows and with lm1. Thats too cool

this is when i did the LM II only



this is when i did LM II with kooks headers



this is LM II and headers take off



then i got a blower cam installed.

One thing you have to remember with the proflow. The proflows comes with mufflers but I took them out and just pipe in there place to make them louder. SLP sells a kits to do that really easy.

Ya I saw that. Would there be a big sound difference between stock H and the stock muffer vs. the SLP X and mufflers that come in the proflow? Or is it common that people remove the mufflers in the proflow?

Wouldnt a muffler delet with the proflows AND a resonator delete be super loud? Thats basically straight piped (-the cats).

IMO SLP LM II is the way to go. Loud but not too loud without raspiness.

Its really loud only when you but your foot on it. But its not really that loud.... Just a little louder then more exhuast.

When I had the proflows mufflers on it, it sounded great in the inside but I wanted much more louder on the outside. Plus I had a little more drone with the proflow mufflers. I'm happy with out them. But I would like a little more bass, but cannot have it all with out taking out the cats...

x pipe = HP
h pipe = sound

Thanks for all the replies guys. Im gonna keep doing youtube searches and order either the SLP LMI or LMII's this week. Would like to go to the track this Wednesday to do a baseline run.

I just installed the LMII's and I am satisfied with the sound, its not as loud as the LMI, but as others have said there is a little drone. The drone is more situational than constant, usually in the 1500-2000rpm range during lugging. I've spoken to an engineer at SLP about adding the powerflow x-pipe to the system to reduce drone, there response was it would probably get worse, I've never heard the LMI's live but it seems to me to just be an expensive muffler delete. I plan on going with the full SLP package next year, LT headers, powerflow mid and I may swap the LMII's for the powerflow mufflers, since I think it might be to loud for me...
