Hi all, I'm looking for a set of long tube headers for my 2004 GTO with a 6-speed, and K&N CAI.

I know I want them to be 300 series stainless steel, and 1-3/4" primary tubes. My biggest problem is that its very hard to find out who out there really makes the best ones, in regards to HP increase over stock.

Call a few tuners and see what type of results they have had with the various headers.

Also, if you are planning a blower later, you should make sure they know that as well. Heat can be an issue, depending on other mods. Size does matter if additional mods are added too.

Good luck! You will LOVE the sound of Headers and exhaust! :

Well, I have heard that Stainless Works and Kooks are the best... but, dyno #'s wise we have gotten the best out of SLP! The fit is awesome, they are very well priced (from me anyway...) and the finish is very nice! Pm me and I'll hook you up!

They are all close in HP and TQ gains. I went with Stainless Works they work and fit great. I went with Stainless works because of the random tech cat imo they are the best aftermarket cats for the money.

Good Point! : I forgot to mention the EASE of Install! Some will end up being MUCH easier to install than others.

Agree here. Now, doing what "research" I have, there's talk about cooking the starter (too close - no coating) and not being able to get the starter off.

Now, in the "other" forum I made reference to this in "Tejas" section and nearly got flamed and got the BS flag ran up on me, but I was just writing of what I heard from more than one person.

I'm just like anyone else that doesn't want to be cooking their starter and then find out you gotta take of the frikkin header to replace the aledged cooked starter. Still have no definative answer Oh, there's some pics of clearance there, too, fyi

Thanks, I've got 11k miles on my car and no cooked starter! The ceramic coating does help, and the SLP headers only take around 3.5 - 4.0 hours to install (if you've done a couple...). Let me know if you're interested!

With the SLP L/M on, and ceramic coating, I'm thinking that's the way to go.

And, I'm sure I can take any 4 hour job and turn it into 12 hours, or is that 12 beers
