Guys we have a release special on the SLP single exhaust 2.5 with a polished 4inch tip . This system is upgradeable to the dual system if you'd like .

Bolt on a Loud Mouth II™ catalyst-back exhaust system from SLP on your 2005-07 Cobalt SS for significant horsepower gains over your stock restrive exhaust system. The tone is deep and powerful letting everyone know you're coming, with an aggressive rumble. The secret to the system's distinctive sound and performance gains is a polished stainless Loud Mouth II™ bullet-style muffler, stamped with our SLP logo. This system features a polished 4" double wall round tip, providing you with the ultimate Cobalt look. The modular design gives you flexibility to change to our louder Loud Mouth™ resonator (# 31062). The rest of the exhaust system is hand-crafted from 2.5" 304 stainless steel, comes complete with hardware, detailed installations and is covered with our Lifetime Warranty.

Retail is $599

Our show special is $499 we will have some here in stock for the dyno day

A buddy of mine had Loudmouth exhausts on his Z28... DAMN is all I could say.

 

That dyno day is this weekend, isn't it?

TTP FTW!

 

Uh yes you have to go to the Dam game .

 

Upgradable to duals?? More info please...

 

I would rather go there and have you hop in my car w/ your laptop and HPT for a quick log...

Oh well, I'll be down there in the Fall sometime. Maybe I can get my dyno graph from you then.

 

They have a dual exhaust system comming out we will have the car hear on the dyno day . you will be able to upgrade the single to a dual . We don't know how much the upgrade will be yet

 

Sweet, I wanna do dual exits. Let us know when you have more info please.

 

I bet someone will get good pics and video this weekend. Stay tuned Joe...

 

is that 499 shipped? if so, lemme know asap!

 

Whats W The Link...??? No Vid Or Thumbs

 

it's louder then a 3in exhaust and I don't like how they still use the crappy factory resonator. Doesn't sound any different then all the rest of them. BTW, seems like the audio quality was low. Perhaps they were using a cell phone camera.

Also looks more like the GMPP exhaust (sport).

 

to what zip code ?

 

Holy crap... what a deal! SLP products are great.

 

We have one left for the show price .

 

i have the slp loudmouth II on my car and i love it, sounds like a honda when the exhast is cold but when it heats up...wow its awsome

 

This is a link to the SLP Dual Exhaust........After listening to all of the exhaust clips on YouTube, this is the one that gets the blood flowing. I'd love to buy one but not for $1000. SLP is a very reputable company and was heavily involved in the Firebird Firehawks. Wish they could sell that dually for less.

You should have come out for the dyno day at Tune Time yesterday, Matt was offering serious discounts on all of SLP's products... If I were you I would contact him ASAP and ask if he would extend the dyno day pricing to you...
