Looks like they would want to exit right on the Pantera chassis member and engine mount?

They are Stainless Steel. If I used them they would need a quick 90 degree turn. I haven't even test fit them with the engine in so I don't really even know if they would fit at this point.

They are beautiful units but I am really leaning towards 180's...


They are nice but shorties really don't do much for you anyway.

They do reduce restriction some but don't offer any scavenging effect.

Maybe a blower engine doesn't care that much?

If you went this far, stepped tube 180's would probably be worth the effort, at least for show.
Won't the other LS headers you had before fit this engine?

I've noticed a lot of the SC engines (of all makes) with short exhausts still blow out some flames when you step off of the throttle.

I got lectured by a local cop that my entire car was illegal. He wanted to know where all of the emission equipment was?

When he found out all I was required to have was a PCV and evaporative controls AND they were there, he was speechless and walked away in a grumph!

I love doing that but I know he is out there lurking with the DB meter somewhere waiting to pull me over and do a curbside test on the exhausts. You just never know when trouble will appear out of nowhere? Wink
