Cat Backs

[lil_foy]

Talking to a mate and he said they most custom catbacks are press bent.

I presumed most people got them mandrel bent due to press bending lowering the overall size of the piping over the bend.

So people, what is your custom catback?

Press or mandrel.

nearly all exhaust shops that fit aftermarket systems for performance gains using mandrel bent

It really depends on where you have it done. Cost is a major factor as some shop prefer to use press bend pipes as they are easier to make up (less work).

Custom can be anything, generally speaking tho, custom implies mandrel!

Your mate is wrong they are mainly mandrel bent
