I already have a K&N filter and a flowmaster cat-back, How much gain do you guys think that has given me and how much more will pacesetter headers and the whisper lid give me? Also where should I get the headers and should I try to install them myself or pay someone to do it? How much in labor should it cost? Also I would like to know how much louder the car will be with headers?

Filter and exhaust probly give u 10-15 at the wheels, 20 if ur super lucky. Headers will give u another 10-15hp, not positive on the whisper but usually intake mods net around 5hp. The headers will make your car loud in a nice way, like ehaust. Jeggs has those headers in stock i believe. As for the install, I would recommend that you look around this site for some installation instructions and judge for yourself if its too difficult. If you have them done at a shop i would say install would be like $200-300.

Anyways, the throttle body has hot coolant running through it. This helps on cold starts but after the car is warmed up the hot coolant warms up the air going into the throttle body , the warmer air takes away hp. The TB bypass reroutes the coolant line going through the TB. This mod has dyno proven gains of 6rwhp on LS1s, this would probably be about 4rwhp on a 3.8l. Not a good to do this mod if you live in a colder region, some people take of the TB bypass during the winter. It's easiest to just buy a TB bypass kit instead of running around getting the parts. The kits are usually on ebay, $5 is a good price don't pay more then $10. The install isn't very hard, it's just rearranging small radiator hoses.

It's kind of funny that you say the KN filter doesn't add any power, just because that's suppossed to be the major advatages of it.
Continuing with the headers, ofcourse the flowmaster sounds a little raspy when you rev it in neutral, will headers help to eliminate that or will they make it worse? So lets say I put $600 into my car to get headers and the lid replacement, around how much more power would i have? remember I already have a flowmaster catback and K&N filter, god that was almost $450 already.

I don't know about the headers effecting the flowmaster sound. If you get full exhaust and the lid you will probably net around 15-20hp at the flywheel.

Since I'm new here, I guess I'll just post some info here. It's Xmas and I can't sleep!!!
My SLP CAI was absolutely wonderful on my car. It sounded awesome, and looked very pretty. I'd highly recommend it.
As for the Flowmaster, that was a mistake. I paid 350 for it, and installation was more of a pain in the *** than any other catback I've ever done (the midpipe just didn't wanna fit over the rear)... it sounds pretty good, but after a few months it started shaking around, and I needed to bring it in to a shop to have a few more hangers installed... looking back, I could have gotten a Hooker catback for much cheaper.

1. K&N filter's main purpose is NOT horsepower gain it is a long lasting reusable filter with superior filtering capabilites.
2. Headers will make your car sound less raspy and better if you put the same exhaust back on (my opinion is it will make it sound better no matter what).
3. With my current mods
Ported Nostrils
Whisper Lid w/ K&N filter
3" Precat Cutout
3" Carsound highflow cat
Pacesetter 3.8 Ceramic Coated Headers
I put 201hp to the ground with the cutout open and 195 with it closed. With just a lid filter and 80 series flowmaster muffler I put 186 to the ground.
Hope this helps you guys.

Catback q'S
Hey guys I have a few catback questions for a female friend of mine. The car is a 99 3.8, auto, non-Y87. She wants to get started with a good catback, but Im trying to convince her that brand name isnt everything. HEr main concern is that her car sound good, and by good she means that she wants it sound more like an LT1 than a civic. Ive heard some catbacks on 3800s that sound pretty "ricey".
1. Which systems should we stay away from that dont provide a deep exhaust note? sh'll kill me if her car ends up sounding like a type R badged civic.
2. How do the SLP take off exhuasts sound? Are these actual LS1 SS exhuast systems? If so one would assume that they would be even quieter than stock, seeing as the factory would want to make the LS1 quiet.
3. How would welding an aftermarket muffler into the SS take off exhuast effect the exhuast note? Has anyone tried this? Im thinking flowmaster or Loudmouth.
thanks guys, Im glad sheridan is fianlly getting excited about modding thecar, so there will be more questions to come!
