...THANKS Denny, didn't see anything on their site that was that small, just baffles in 2 1/2", 3", 4", etc... But I'm tired so may be I missed something. Went to the Sanderson site & also didn't see what size tubing their small block Zoomies are. I read some feedback on the Sanderson site from someone who has their Zoomies {that come with baffles} & he said they were so loud that he got complaints right away. He also said he bought more baffles from Car Chemistry but hasn't installed them yet. Tomorrow I'll call Sanderson, LP Performance & Car Chemistry & see what they have... Thanks again, goodnite, I'm turning in Bill
