Is the SLP Loud Mouth exhaust a bolt on.
Or will there be some sort of Mod needed to be done for it to match up to the stock exhaust?

I would imagine it would bolt on in place of the stock exhaust.

I only ask as the pictures of the SLP Loud Moth lool like they start with a bolt on flange.
And looking at the underbody of the GTO's exhaust.
It looks like the system would bolt onto the stock exhaust some where before the stock Mufflers.
But in the photos I have seen it does not look like a matching flange on the stock exhaust for the slp to bolt to.

Hence the question does it just bolt on.
Here's one more question.
Would I be able to do this myself on a garge floor versus on a lift.

I beleive I have seen a picture which answered my question , it looks like the SLP will bolt onto the stock exhaust after the cat's and stock resonators.

But my other question still stands , will the car need to be on a lift for me to get the exhaust on .

Well that depends on what if any tools you have in your garage. Any stands or lifts?

I have jack stands.
not sure if it would get me enough room.

I used jack stands on mine it took about 15 min after getting it in the air to remove the stock exh. may be 30 min to put on the new. no mods at all required. took a while to decide on the best look for the tips

Thanks for the help.

I'll give it a shot to do it myself :D

So how did the project go. Did you have any problems? Got pics. I want to install it on my 04 as well but wanted tos ee if you had trouble.
1-10 how difficult?

Sorry about the Delay.
Actually bought the SLP Loudmouth and a speed induction air intake
From tbyrne( Great people to work with)
Ordered parts on a friday and had everything on the following Tuesday.( Late August)

I got home from work at 5:30 PM had exhast on and the new Air intake on by 9:30PM

The install was very easy on both, you just need to follow the instructions that come with the exhaust.

As far as on a 1-10 scale 10 being the hardest. I'd rate the install as a 3


I love the sound of the loudmouth, as well as my baby can breath a bit easyier with the new air intake.

Looking to tune the goat now.

maybe a supercharger over the winter when my baby hibernates.
:friday:

Did anyone get the SLP Loudmouth and it wasn't extremely loud cause I just got it installed and it wasn't as loud as I thought it would be if anyone can tell me

I got the loud mouth and there was a little change. Then I put on long tube headers and the sound is nuts!!!! It honestly sounds like a race car. Get the headers and the loudmouth and you will not be disappointed :D

I've got the same setup.

My boss was following me home yesterday, he made sure to call me and point out he heard me 1/2 mile away taking off from a stop light.

I've only ggot the loudmouth on my car and I want to do more mods but the problem is I still have the warranty and I don't want to void it. Does anyone know anything I can do?
