In all honesty, if you're going to go through all the trouble to change the exhaust manifolds on an LS1, just get long tubes. If you get shorties or mids you'll end up wishing you just got long tubes in the first place.
Most LT's are available with emmissions provisions as well.

Shorties are a good appearance mod and do show small gains especially before the manifold redesign in 00...nothing compared to LT's but 5-10 rwhp depending on other mods

Yip... they are Shorties
I received the headers that they were advertizing on EBay as Mid Tube headers ad read "These are PaceSetter’s MID-Tube Ceramic Coated Headers". They are in fact Shorty Headers. In their defense and in the small print further down they called them Shorty headers. My bust but am going to install them regardless. Wish I had a base line and I would let you know what they make in gain. I will however dyno anyway and report back and include the other bolt-ons.

If I recall correctly, the stock LS1 manifolds are also stainless steel as well, which is a nice benefit over most aftermarket shorties.

I finally removed the stock headers. They weigh approx. 12 lbs each. The PaceSetters weigh in at 7 lbs a piece. The exhaust tubes are routed slightly different and both are steel.

The runners are longer as seen in the picture. I didn't have a base line but plan to put it on after installed. I will post what the mods (in my signature) net to include the headers after the dyno run.

Examples, Note the length of the new head pipes in each auction.
Shorties, ..., (Even tho the one auction states 'mid', ..., they are really considered shorties.) Shorties, as mentioned, simply replace on the factory cast iron exhaust manifold.
Mid-Length, ..., Will require either moving, or removing, the cats original location.
Mac does offer the same layout, with the additional cats, one in each side of the y-pipe.
Long Tubes, ..., is there really any explanation necessary?!?
These are simple, quick, easy representations of each style to help people understand what the terms are referring to.

Good job for "show and tell".

Where are the dyno numbers!!!!???? After 2 pages of this shit, I really want to know.
Yeah, they dont look that different in design. Look better though and it looks like the bolt pattern wont line up directly to the y-pipe/converters.99 T/A M6

Mid tubes are simply that mid length between long and shorties. Some companies don't truly have a mid and a shorty such as pacesetter. The best mids I have seen are made by heddman. You can get them from jet hot with two coats ceramic with a lifetime warranty for around 400.00.

got my MAC mid lengths today
I choose to run the MAC midlengths cause I have my 01 SS riding on eibach sportlines, (dropped 2"). I was told that shorties were just a waste of time unless looking for engine dress up, well I was looking for something that was gonna net some power but not get snagged up at every speed bump. Although not installed or tested yet I will keep in up date on a lowered SS with mid length header platform Here are some low res pics that my bro sent me, seeing that I am 3000 miles away from my car
copy and paste srry!
