Looking into basic bolt ons
Hey guys. I plan on keeping my ws6 stock for a while but I figured I would post my ideas and see what you experts think. Right now I have a ws6 with the m6, magna flow cat back with k&n's and a healthy 22,000 orginal miles. If I were to guess id say the car is putting down around 310-325rwh, and good for 13.1-13.3's at around 107? Anyway here is my list in order if something is out of place just let me know.
SLP air lid. I guess this simple mod is good for 5 hp at best.
Headers- I have a few questions here. I was thinking of getting pace setter. Decent? Also can I use the stock Y pipe to save a few bucks?
LS6 or Fast 92mm Intake manifold. Now I was told that that stock ls1 breathes enough to where it will not benifit from an ls6 intake without a better cam. Is this true? I believe the fastest stock F body was a 99 z28 that ran 12.85 and put down 321 hp by the guys at muscle mustang. http://www.stangbangers.com/01_Bullitt_Article2.htm. Either way its probably debatable. Thats why I will probably go with FAST 92 then port the stock TB. Anyone have any input?
I do not plan on doing engine work such as cam or heads.

the fast works pretty good, but they now have a 102 mm lol, but i would go with the 92, sucks in some air and sounds good

What year is your ws6? if 01-02 then you have a ls6 intake.

I just hit his user page to check the same -- by the OP's user name I was wondering if he has an '02 also.
Sounds like you are on the right track - change out the lid and stock paper air filter. Rather than a K&N or something similar, check out the Amsoil Ea Air Filter which you can order through CompSyn's link on this site. Leave the MAF alone, except to clean it with a MAF spray cleaner.
You can also change out your thermostat - a lot of guys drop down to the 160 degree, but I went with a 180 degree thermostat. I think the stock stat runs 195-197 or so. You will need to have your fans reset to work properly with a new stat. You can also bypass your throttle body - there is a coolant line running from the air bleeds at the top of the head, through the t/b and back to the radiator.
The next mod to consider -one I am picking up next weekend - would be a set of subframe connectors. Enjoy and keep us posted on your mods. I am sure some other members will fill you in on the headers and Y-pipe.

Here is the best time I could find for my car. I wonder if I could hit 12's with just cat back, filter, and radials.Last edited by Mike0202; 06-21-2009 at 06:34 PM.

If you plan on keeping it stock, and nto going loud and obnoxious like the rest of us yet, the intake's a good start with tuning, ported tb will pick up a few more horses, a couple of the free ram air mods/ lid/ ftra (or the metal ducting up to the air lid).
as far as headers, I know everyone likes pacesetters because they fit well and are cheap. If you have the money, for about $570 you can get a set of stainless steel hooker headers from byunspeed. The ORY, you want to get aftermarket, as the stocker is nothing but a giant restrictor. The catless y will pick up a few horses too. The tuning is good for another 10 hp or so, and you'll be runing right.

Flame Red / Orange Custom- 1998 Trans Am
I would do a cat-back or axel back exhaust system not too bad in price air lid is a good choice, Throttle Body is a really good one and it is easy to install but get a spacer it helps and it sounds cool and if you get headers you have to get a y-pipe unless you don't go long tube you can look around to find some but with long tubes you will get more power and you can get a set of ARH with High flow cats and y-pipe for about $1,400 thats what i did got them from LMperformance.com

Don't bother with the intake manifold, don't get the FAST either, it's not worth the money unless you are doing heads/cam or something radical.
Start shopping for headers, there is nothing wrong with pacestters, but if you get them, get the ceramic coated ones. There's a lot of choices out there for these, then get an x-pipe and pick out your mufflers.
If I had to do it again, i'd get an x-pipe with spiralflows..good luck

Yeah the TB Spacer was what i was talking about, I have the BBK 80mm TB with spacer and it makes a little whistel at the right RPM sounds kinda cool i had people at the track who thought my car was a turbo but i just told them no it was just the Throtle Body & spacer.
