Help with Exhaust Band Clamps My friend has just bought a 1995 Z28.
He is planning on getting an exhaust setup like mine -see sig.
My exhaust was put together using U-Bolts (look like crap).
Hope someone can lend their experience here (and I hope this makes sense).
As my headers (ceramic coated) ran at around three and one eighth inches OD diameter and the ORY (not slip on -my were slip on tho') runs at three inches OD diameter, would a three inch flat band hold these tightly together -one tube slightly larger than the other.
Also on the ORY, somewhat of the reverse.
The opposite header pipe (to complete the Y) slips inside the rest of the Y, So this means it has a larger OD to accept the three inch pipe, so here would a three inch stepped band clamp work here ?
Guess what i'm asking is, how much of a tolerance is there, do the connections have to be exact, or is there a little stretch in the clamps.
Thanks in advance guys.

Look for 3in. lap-joint band clamps, that is what I used with my old Pacesetter setup, dont use a regular 3in. band clamp. The one diameter is 3in. and the other is I think 3 1/8" and they worked perfect.

just a heads up, I just remembered they may not work for the connection of the LT's to the y-pipe because if I remember correctly the 02 sensors dont allow the clamp to fit on all the way but I could be wrong if I had my old car Id look for you. As for the connections that the y-pipe connects to its self and to the catback they are awesome.

He'll be getting a set like mine, so I'll check mine out in the morning.
Thanks again
