IMO this is one of the best sounding exhaust systems out there, and when you consider it's $300.00 price, it's very hard to beat. SLP introduced this exhaust for the LS1, but there were so many LT1 owners that wanted it they have started selling it for that engine also. Its 409 stainless construction with 304 stainless tips...either dual/duals or 3.5" slash cuts. I used to think my 2-O-T-L was one of the hottest sounding systems out there, but the Loudmouth puts it to shame. Just curious how many people would be interested in buying this system if it were available for the 3rd gen cars.

BTW, you really need to hear this system in person...I have yet to hear a sound clip that does it any justice...

I would. The drone doesn't bother me either that they have on LS1's. I have yet to get this exhaust for my LS1. Would be cool for the iroc too.

...it's a catback system with 3" intermediate pipe, a resonator (hollow tube) just forward of the axle, no muffler and terminates in either dual/duals (2.5" x 4 tips) or two slash cut 3.5" tips.

...it IS loud...

...well, with your replies and other people I've spoken with there are close to 40 people who are interested so far. I'm going to get with SLP and find out how many systems they would have to sell to consider it a profitable venture. They could use their current 3" intermediate pipe, cut it and put the resonator inline, so they would only really have to come up with the over-the-axle pipe (which could be the same one they use on the LS1 and LT1 systems) and the two tailpipes, which would need specific hangers...

...they could use the same tips they use on the LS1 and LT1 systems...

...and it wouldn't be a really big deal to make a 2-O-T-L version...

Umm, i'll take my loudmouth in stock exits please. Heh, just don't like the 2OTL look. Anyway keep us informed on what SLP says, etc.

Would it be louder than my borla?

 

If you're running you're Borla with the largest open plate, it's probably pretty loud since most the exhaust is going out your passenger side pipe. On the Loudmouth, it exits pretty equally out both pipes. The Loudmouth has a deeper sound to it and IMO is not as raspy sounding as the Borla. I personally think the LM is louder than the Borla on the LS1, but since I've never heard a Loudmouth on a 3rd gen car, I'd just be guessing...

Well, this isn't a 3rdgen car but compares borla to the loudmouth none the less.

Heh, if SLP won't make one for thirdgen's, i'm tempted to fabricate one myself.
