in the back of the new HPP is an SLP add. it shows pics of
18" HSV wheels for $1199, wheels only
SLP LOUDMOUTH for $599
and
1 5/8" Midlength headers for $939
i haven't seen these items on their website. so either their site is behind or they dont actually have them yet.

also right below it is an advertisement for LG motorsports. but if you go their website, they have NO products listed for the GTO. nice waste of money.

My Friend works at a speed shop and showed me the catalog. The Mid-length headers are Stainless and come with a cross pipe and cats. Maybe 900 plus bucks ain't so bad after all.

I want the loudmouth but I am concerned about the noise level for stupid California ordinances - 95dBA max. Apparently stock we're just shy of 80?

That's correct. Now Stainless Works on the other hand, I asked them about it and they said we don't know but if you tell us what the test method is we can try and find out. So I figured out the method and sent it to them so we shall see.

I had a Loudmouth on my '99 Trans Am. I hated it, the drone at 2000 - 2500 rpm made my teeth buzz. I wound up with a Corsa cat-back and loved it.

Chances are that the loudmaouth would be different for a true dual exhaust. I don't know

The SLP headers are probably still a ways away. I see this with alot of new products. Their GTO catbacks should be ready to ship soon.

I am interested to know if the Loudmouth for the GTO will drone at that rpm range? If it doesn't sign me up, I will order it! The stock exhaust is to quiet for my liking.
