I completely v-banded my old LNF exhaust with parts from silicon intakes.

I never once had a problem.
The clamp I broke was on the V-band on my stock exhaust. I was almost ready to stop tightening but decided one more quarter turn and SNAP!

Usually high flow cats, and exhaust setups will have some rasp when they are cold.
My resonator will rasp if I lay into the trottle a bit when she's cold.
Once warmed up, I have zero rasp

injen intake
other stuff that doesn't rly pertain to the vid
not tuned yet for the setup
ok everybody, at long last i got a chance on lunchbreak to take a good couple videos of this setup. at the moment i'm still afraid theres a teeny tiny leak SOMEWHERE but idk... i can hear it hissing under boost. this may well be the culprit of any 'rasp' you will hear in these videos, but i'm not so sure.
extra disclaimer: the code on my dash is a p0420, and no i haven't been tuned for this setup yet so the gains should get better, idk if i'm running rich or lean yet...
anywho, once you let the exhaust warm up for 5 minutes, the rasp is basically gone and the car sounds amazing!
almost like stock, just with a little more noise and tone. the gains are feelable, as well. i feel the most gain in the high rpms, when its cool out now my car feels like it wants to break the tires loose and generally that's just not the case. 
install wise, it is a PITA, of course. i had to remove my strut tower brace to fit it in from the top, but once the headers on the DP is a sinch to clamp on with le` provided v-band clamp.
so, enjoy the vids! a few vids have the windows down, a few up. one vid the camera's outside the car and in one i do a 0-100ish pull! problem, officer?
windows down, skip to :14 if you just wanna see the action, regular 1st gear, then get on it a bit in 2nd up to 40mph.

this one i drive mostly regular up to 50, then stop, then go through 1st, then mash 2nd and 3rd for a bit. windows down till the end i think

outside the car!
to give you a good idea of how it sounds from the outside, i start it, then drive back and forth a few times

aaand the 0-100 pull skip ahead a lil bit, i'm jus cruisin through traffic a bit at first but about half way through till the end i do a pretty good 0-100 pull with the windows up
