Just wondering how to do this, first time installing headers ever. I have the bolts, gaskets and headers (of course )...


What other supplies do I need?
How much louder will my car be?
Will the tone change much?
what is the best way to do the install without moving the engine?

Thanks for your time!

Take a look at the front page -- someone is asking the same thing. Also a search will turn up more results than you'd ever be looking for.

...and because I'm not a total dick -- check out these two writeups. They should give you more than enough info to get it done. Set aside plenty of time, and have a lot of patience and it'll go just fine.

To answer your questions:
The car will be louder, depends on the rest of the exhaust system -- and what kind of headers you are running. If you have longtubes and an off-road y-pipe it'll definately be louder. The 'change' in tone is subjective to whomever is listening to it. Personally I think mine sounded a little smoother, and got a little deeper.

I am running LTs with a 3" all the way back to a flowmaster muffler. I run an open 3" cutout at the track usually.

It will definitely be louder over stock, but not bad. My car got quieter than the flowmaster muffler previously on it... untill high rpms atleast. It's all about the catback.

yea the catback chokes it some..unless you have a gmmg or td's. will sound deeper and much louder.
it's not too bad a procedure..won't be too bad.

its easy from the top but you have to take all accy.s off and tip the motor side to side. took me like 4hours. oh and take off the steering shaft. it will sound deeper and way louder
