Exhaust Switching/Let's hear you guys' Opinions!
 

Greetings, guys!

I must apologize for my lack of posting. College has kicked my butt. I used to have an 01 SS, but now that I have graduated, I now own a 07 Monte SS!

I've owned it since 2013. I will post photos of it once I have the time, and once my setup is finished!

Currently, I have a pair of Series 40 Flowmasters, with a Res Delete, and Resonated Tips. Although I love the sound, I'm looking for something a bit louder now to prepare for next spring.

I'm specifically looking for the SLP Loudmouth 1. I know there's a couple of members in here with that Setup in this forum.

Where I'm stumped is, which type to buy.

I know some guys claim that they are "Mufflers", but from what I've researched, they're resonators.

Does anyone know what specifically they are? Also, what size do I get? From my research, it says that the SLP LM1's are Resonated at a 2.5 Diameter, but the 3 inch ones are considered "Mufflers." I just don't want to get the wrong set, to potentially compromise the potential sound.

I'd like some help from the Experts!

Thanks guys! :thumbsup:

Best bet is to check youtube, SLP loudmouth 1 or 2's are the way to go for LS4's. You would probably want 2.5" as that'll fit better into your factory system. Technically the 1's are considered resonators while 2's are mufflers.

Here is a video of one

That's actually the sound I'm trying to replicate!

I just wanted to know if there is a specific product number that I should buy to get that sound. I just don't want to get the wrong parts!!

Thanks for the reply!

Also, since you confirmed at all Loudmouth 1 iterations are "Resonators", does it matter which LM1 Variant to buy, so long as it's a 2.5?

Here you go buddy! get two of these bad boys and cut your resonator out!

Best sound out of a LS4 IMO :) enjoy!

Thank you very much man!

I'm actually a huge fan of your specific Monte. So I'm definitely glad you could give me the Input I needed to replicate your system.

No problem man!
And thanks! :D You'll love the SLP's, def turns heads everywhere

Definitely. Thank you for answering my question!

Now I must ask you this..

Will the sound be replicated if I just bought ONE of these? Put it in the old Res spot.

Or, is that a not-so-great Idea because in some States, no mufflers are illegal.

I have not heard it with no mufflers and the in place of the stock resonator so I really can't answer that question (nor have a heard of it being done, so you could be one of the only ones) but in the "Car world" Those SLP resonators are called SLP loudmouth 1 mufflers because pretty much everyone uses 2 that uses them :)

Another question for you.

I notice that it gets a LITTLE bit raspy on Park on yours.

Did the Rasp go away once they broke in a little bit?
