yea, i just came back from MIDAS and they didnt even know what mandrel bent was. They said they'll bend me (crush bend) a custom 2.25 inch piping aftercat and weld onto a muffler i bring for 150, but crushed bent is no good.
that's your problem right there, never go to midas or mienke for a custom exhuast.:nono:

you need to find a custom exhuast shop and honestly unless your making big power I wouldn't worry about mandrel bending. Most shops will not have a machine to do since it's cost alot of money. Your best bet is to either:

1. Buy a name brand catback if you can't find a quality exhuast shop

2. Go to a custom exhaust shop and have them order some mandrel bends to put into the exhaust piping. Companies like magnaflow sell bends in a few angles.

Sorry to be so annoyin, but heres another question. If i use crush bending method but try to make the pipe as straight as possible without hardly any bends, won't that work just as well as a mandrel bent pipe? Cause i'll pull the pipe straight from the cat and under the axle and a little bend to point up and muffler at the end. How does that sound??
Thanks.

that's exactly what a good custom exhuast shop can do. the best places can crush bend so it's almost as good as mandrel.

Sounds good except for the bend at the end. If you're going with the "the chain is only as strong as the weakest link" theory -- power gets stopped at the first small point -- it may restrict you. But I guess the bend wouldn't be that much smaller than the rest of your piping considering where you're putting it. Also, it's only one, and if you get a good shop to do it like AccordSleeper said, then you'll be well off.

one crush bend restricts flow up to 50%, but i think the average restriction is around 40-something percent for a 90-degree. even the little bends of a crush-bend may restrict flow (not as much) but it will cause turbulence on the behalf of the crushed area. so i would say that your best bet is to go with the straightest pipe (hopefully you can clear all the parts you need without bending too much), and even consider a center exhaust as to reduce bending to the side...that is if you dont mind the viper/corvette look on your accord. :P
