Naw..... I guess not. But everybody needs a snack every now and then... :yes:

Tom, did you design these to work with an X-pipe of your design?

Unfortunately...... no. It would be real hard to fit a 3.5" true X-pipe under the chassis. The ride heights that we deal with would make it difficult.... but a drag car wouldnt have a problem. You could with our typical ride heights....... pull it off if you went with 3.0".

Another note..... you do not necessarily have to run 3.5" for the entire system. The collector however, has to be 3.5" but aft of that can be a size smaller. The recommended sizing is 3.5" to the front of the muffler and then 3.0" aft of that.

Could these potentially work with the LS2 and LS7?

Basically, yes. There is no real difference on the exhaust side of the LSx line up. The engines are: LS1 = LS2 = LS6 = LS7. Where they differ is on the intake side of the LS7. The bolt pattern and spacing is different from the rest of the LSx line..... and the valve angle is 15* on the LS1/2/6 and 12* on the LS7.

The only notable difference is the flange of the LS7, it has a "D" port exhaust. We also have CNC'd flanges for the LS7 available now as well.

:unibrow: Good to know, now lets see some dyno results. There is a LSx motor in my future that will need exhaust.

Dyno results........ thats a good one, considering that we would have to take the engine package you are going to run and swap all the available headers onto it to see net results. These are not a barney bolt-on, off the shelf pair of headers. Every set of our headers are taylor made to the engine package and obviously every package will net different results. It really wouldnt be fair......

I guarantee these headers will make more peak power and make more power under the curve than any other header available on the market for an LSx swap into a first generation Camaro.

I am not doubting ATS's abilities by any means. For some reason I like numbers and after seeing the thread on the LS7 header install, I was curious. I have narrowed my motor choice down to a stroked LS2 or stock LS7 (preferred) depending on availability and will require the sale of my '69 Blazer once finished to finance the powertrain package. I know you guys will be getting a call when I get a few more things ironed out and a little further along.

Mike

Will these fit in an A-body, namely a 72?

I'd be up to see if it fits with my engine/tranny combo... 6.0l/4l80e. Its pretty far back in the engine bay. Camaro exhaust manifolds clear, 6.0 ones don't clear. They need to tuck against the engine but then have to go around the tranny.

I'm up for guinea pig status. :unibrow:

What company built these headers?
