I washed the goat today and it's looking great. i than got my cam and said to myself "i should make a exhaust vid to hear what others have heard as i go past them". plus i need practice at this new vid cam. the first rev is to 2300, the second is up to 4000 rpm and the last 3 was up to 6500 rpm. enjoy

Your exhaust system sounds perfect, one of the best ones I have heard on line. Could you please provide the details: part numbers, the cost, etc, I want to see if there is a comparable set up for the 04 GTO. Thanks.

very nice

I bought the SLP Stainless coated headers with downpipes and highflow cats.
and also got the SLP Catback LM1 (loudmouth 1) exhaust. comes as 2 different kits. I got mine from Maryland Speed. Branden is the owner and a really nice guy to work with. he gets your stuff out asap. The cost should be on his site.
Before ya order , e-mail him to make sure everything is in stock.
I had to wait 2 weeks on the headers cause SLP was behind in production.
But they should be caught up by now. MIne was the 05-06 kit , they have it for the 04 too.
Glad you all like the sound. I really like it . Makes it sound badass.

Thanks for the info, I found the 2 kits, looks like a little over $1800, not too bad. Next questions;
o How were the installation instructions?
o Was the installation pretty straight forward?
o Did you have to use a lift or are ramps sufficient?

Instructions were good, and if you look around you can find some instructions on the net with pics from guys that have done it already. really not much to it, everything bolts together and pipes are prebent, just twist them a little here and there at slip joints for adjustments. I think you can even get a 05 replacement piece for your 04 , so you can run pipes out each side, and use the 05-06 kits.
I know there are some guys around that have converted and maybe post a thread and see who answers on that question.
I you have access to a lift is best, but if not, put her up on ramps and jack stands.

Appreciate the info. I noticed that the system you purchased does not come with mufflers, only cats and resonators. Then I see from the web site that you can use either the resonators or high-flow mufflers. Does your system have the resonators or mufflers? And if the resonators, is it too loud.

Sorry for so many questions, just trying to make sure I purchase the right system. I would love to hear it live, but not sure if that will happen.

Copied from the web site;
•Exclusive modular design allows easy interchangeability between resonators
and SLP high-flow mufflers

there are actually 4 setups possible.
Headers with highflow cats and the LM1(loudmouth1) catback exhaust system. LM1 is just the resonators.
Headers with no cats and LM1 exhaust system
Headers with cats and LM2 (loudmouth 2)catback exhaust system, which is a muffler instead of the resonators.
or Headers with no cats and LM2 exhaust system.

no cats could present a problem at inspection time if your state requires one for new tags like mine does, or they give emissions tests. or unless you know away around it ,someone to pass it for ya. I went with the highflow cats , no worries.
it is best after an install to get a tune done, and make sure no errors are going to start popping up and tweak the computer since you added headers.
Good tune can get ya some extra HP.
Mine is the Headers with downpipes and highflow cats, and the Loudmouth1 catback exhaust which is resonators only.
hope this helps ya out.
Oh yeah, you can swith the mufflers or resonators out, they are the same size, just loosen a couple clamps and take one out and replace it with the others if you want it quieter or louder. resonators louder, mufflers a bit quieter.
