I was thinking they might provide a relief point for expansion too

I did however use them at a slip joint in my down pipes. To date they have been flawless. I purchased mine through a local heavy truck parts supply. It is my understanding that heavy trucks use these frequently, but again, I don't know if they are acceptable in the higher pressure area upstream of the turbo's.

Use these, http://cgi.ebay.com/ebaymotors/OBX-2-5-V...sQ5fAccessories They have a inner flange for positive seal. They are a bit pricey but well worth it. I paid more for the 3". $38 shipped and I used 5. Last edited by CUUDAK; 05/31/11 10:15 PM. SRT8 CHARGER "Four door bore" <img src="/ubbthreads/images/graemlins/smile.gif" alt="" />

I had the best luck with ball flange as they are more forgiving. 11.67@118 1.88 60' with only 7-8 lbs of boost.

Even when used on exhaust the part where the band is pulled together almust always has a slight leak that you can see when you remove the clamps. Nothing you can hear or worry about on a exhaust but on a boosted motor

I just want the ease of removal because I'm mocking it all up on my 273 then taking it all back apart to clean and paint it to put it back on the 318. I'm sure the 318 isn't going to last long under boost anyway lol so I don't want to have to fight it when I go feeding it shortblocks

The pipe will go into the flange about a sixteenth of an inch. Be sure to hit the edge of the flange with a 36-grit disc so the weld doesn't splatter due to contamination. I made the mistake of buying "Aluminized" mild steel pipe. Hard as heck to get that coating off for welding!!

Got all my pipe from them too, and the straight vs bends seemed to have a decent variance in the OD, so some of them fit tight, some had slop that made it harder to get a good joint. 70 Sport Fury 68 Charger 69 Coronet 72 RR
