anybody know much bout these particular longtubes? and do you know if they work better than the other longtubes like kooks, qtp, or jet hot?

They claim to have good ground clearance. That's all I know.

 

Don't they only come in 1 7/8? I saw them in HPP, or maybe GM High Tech Performance. Looked real nice, do they not sponsor this board anymore

 

I have them on my car. They have good clearance. The Y-pipe could probably tuck up better however. They were very easy to install. The only thing I don't like is that one is a little longer than the other. I just dynoed tonight. With my lid, Super Sucker Ram Air, Comp cam 224/.581/112, and the TPIS headers my best pull after tuning was 393RWHP/380RWTQ.
