Mandrel Bends
Mandrel Bends I am in the process of doing my own 3" exhaust setup. I had a couple questions.
1.) Do mandrel bends make that much more of a deference over non-mandrel bends in HP?
2.) I have mac headers & ORYP; If I had it flow straight trough the y-pipe to the I-pipe and out of the exhaust pipes in the back w/ out a muffler of any sort (straight pipes) will I lose HP?
Any help what so ever would be GREAT! Thanks.

Re: Mandrel Bends Mandrel bends make all the difference in the world. The stock system is mandrel bent 2.75" and will way outflow a 3" non-mandrel system. A 2.5" mandrel will keep up with, if not outflow the 3" non-mandrel. It really is a big difference.
Good luck

Re: Mandrel Bends Yeah, I'm just talking pipes. When you get into mufflers it's a whole different ball game. They all flow different amounts.
For example:
Borla flows around 900 cfm
Magnaflow flows 1100 cfm
Flowmaster flows around 350 cfm in the crossflow design
DynoMax bullets (24222 & 24219) flow 2200+ cfm
You can see the performance mufflers vary greatly.
Good luck

Re: Mandrel Bends I would probably run a Dynomax Bullet... in fact, I am running one, but that's another story. For what you want to do, I would use a bullet... it would increase the quality of your sound and drop your interior resonance.
