I just signed up to the LS1 club, I was just wondering what would be the best exhaust system for a 99 trans am WS6 to include headers?
and what is the differance between long tube headers and the regular short headers?

SLP are the worst headers on the market, along with many of their other products. Bad quality, over-priced, and piss poor customer service to name a few.

Headers: Kooks/ARH/Pacesetter - From best to good in price and quality. The main thing to go with in header selection is Stainless Steel if you can afford it.

Exhaust: Personal preference, but the most popular is Magnaflow. GMMG, Corsa and Borla also make nice pieces, but are very pricey. If you plan on keeping the stock manifolds, which it doesn't sound like you do since you are asking about headers, SLP Loud Mouth I/II sounds nice on STOCK manifolds. It sounds obnoxious loud with aftermarket headers.

www.ls1sounds.com has many different combinations, but it is still difficult to get a feel for the "true" sound of each as hearing over a computer does not compare to hearing it in real life.

Pretty much what 35th said.

Kooks headers and Magnaflow stuff on my car.

AVOID SLP

As long as you avoid SLPs sad excuse for parts, you get a passing grade. If you put SLP crap on, you get a failing grade.

The difference between LT's and shorties is about 20 hp...

See my sig for the 02's exhaust details.

I have a 99 30th anniversary t/a, I put pacesetters and the hooker catback exhaust on it with an off road y pipe, it sounds excellent, it is a bit loud. My car is garaged kept and gets few miles so I did not worry about the stainless, I also live in Florida so there is no salt etc. Whole system was about 1100.00, get the coated headers for sure. That 1100.00 did not include someone installing it.

I would recommend coated as a second option. Get stainless if you can afford it.

I have long tube headers with a 3 " texas speed cross over pipe with magnaflow exhaust and I love it. Sounds mean as hell when you romp on it.

Pacesetter Ceramic Coated Race Style LT's, TS&P 3" ORY, Cats Deleted

Highly recommend coated headers over painted.

This was taken after install before Frost Tune

Also a week later I had to get a new muffler because I blew the baffels out of that one. Now running a Magnaflow

As others have stated as long as you stay away from slp whatever combo/choice you make should be fine. I purchased a y-pipe from them 4months ago and i'm regretting it

What is that bad about SLP headers? I just purchased a set of LT's.

Over priced (when bought new) + ground clearance is poor.

Also, cheap stainless used.
