it fits great, nice and snug. no problems what so ever
mine setup is the elbow the 4" afm came with with t bolt clamps, never had a problem.
you could always try to use a little hairspray on the inside of the rubber so it acts like a light glue kind of. i used that on my TB before i changed to all t-bolts and it worked great.
^^ I dont like the elbow Brian, I got mine in and its about 4 inches shorter than the AFM version.. ill get some pics..
did you see the pic of mine? i had to go to peb boys and buy a polished piece of aluminum and another 4" to 4" coupler but it came out nice and will never come off. I bought a piece of polished aluminum with a 22* bend in it and cut a little of and it works great. like i said a little more work and money than i wanted but i like the end result.
