does anyone have pictures of what the different types of bends look like? (ie mandrel bends, compression bends, etc)

 

anyone?

I'm asking because a local muffler shop told me that mandrel bends have crinkles like the factory exhaust.....they also said that Flowmaster techs have claimed that they hurt exhaust flow......to me that doesn't sound right

 

mandrel is smooth
compression has crinkles

flowmaster cat backs have mandrels

your local shop is acting like many local shops act, retards. mandrel bends are better, how much better can be disputed, but they are better. flowmaster techs have probably never said such a thing. for their stupidity i would never go there again, but thats just me.

 

that's what I thought.....
