Anyone do headers with stock exhaust?
anyone do headers with stock exhaust, to keep it somewhat quiet and pick up some HP, and how much HP did you get?

I had the stock exhaust hooked to my LG longtubes,hi flow cats and LG midpipe. The sound was nice, kinda like an exotic while revving. I swapped out the stocker for the lighter and louder SLP loudmouth 2 a few months ago and now it's pretty nice, just slight drone with windows up and at 80MPH, but not unbearable. I picked up about 30-35 rwph with the headers/cats/midpipe over stock .

originally I had Kooks headers with hi-flow cats and x-pipe into stk exhaust. Gained 30rwhp with tune on an a6. Slightly louder but after 6 months ordered the magnflow axelback for a little more sound and I don't like the smallish looking stk tips

We have the headers and stock catback on our 07 now...sounds a little louder at idle..but pretty much the same otherwise. The Corsa Extremes we have waiting for it will change that.

Take a look around and see if you can find a Z06 guy that has done headers. They might just sell them cheap.
I will post results after install probably next thursday!
Will be Racing either Friday or Sunday

Not to hijack the thread, but I just got factory Z06 manifolds, cats and H-Pipe, with 02 extensions (FREE!!! ) Will be doing the install next week. From some of the other posters that have done this, they are getting 26-30 rwhp from this swap.

And before going through all of that labor to put them on I would need to know that for sure, otherwise it would still be best to stick with the 'tried and true' long tubes that we've all come to know and love.

I do have access to a set but I also have a hard time believing that they will actually deliver 26+rwhp on an LS2 all by themselves.

IF it gets 15, that puts me at over 380 to the wheels! (on a very conservative dyno)

I'm going to the dyno this morning. I have Stainlessworks 1 7/8 headers with their x pipe,cats and NPP exhaust. The car is pretty lould with the NPP open not bad at all with the NPP closed, just a little bit loulder than stock.

I went with the kooks 1 7/8 headers w/o cats through the stock exhaust. No drone or roar while cruising, but it sounds pretty good at WOT. The wife doesn't mind taking long trips in the car now. She would definitely complain if it had Bullets or Stingers

The comment about the wife riding along can't be discounted. I've recently installed Bassani headers, off road cats; actually their whole system - with the single muffler serving as the cross over. The sound is great. Low and throaty and screems at upper RPM's.
Now wife doesn't wish to take the vette. Gotta be considered.
