Re: Mandrel Bent Exhausts

[andrew smith]

Daniel, I've done a few 3" mandrel bent systems on 1600 and they've cost me between $200 to $300 depending on how many mufflers used.In W.A. no cat is required.I use 3 180 deg bends at $25 each a length of straight at $60 a Dynomax Race Magnum Bullet at $60 and sometimes a Dynomax Race Magnum muffler at $100 all of which are straight thru.Only use straight thru type mufflers.The dynomax race series are fully welded and have a thick wall thickness, I reckon there good value for money.It takes a full day to do the whole system at home including the crossmember hole.I recently fitted a length of flex pipe to my system and it took out all the vibrations.

Im running mandrel 3" stainless off turbo, into 3" mild to the rear xmember, then into mandrel 21/2" thru xmember with one 21/2 str8 thru muffler at the rear. From turbo to the xmember only cost me $245. Hardly worth doing it yourself. Mate had the full 3" system done at the same place for $550 including mufflers. I would suggest using one str8 thru muffler at the rear, and theres no need for a cat at all, thats one advantage of a z18et!!! If your going all the way 3", which does sound nice, youll need to enlarge your xmember hole to 4". Cheers Steve.

What sort of muffler do you recommend at a reasonable price?

Do u have access to a hoist? Do u have a bench saw? Linisher? Stands? Another thing with mandrel systems, you never really know what degree of bend u need until your up to that point so its hard to say exactly how many bends of what kind u need. Its alot harder than press bend systems! The Walker cat is ok i guess but NO muffler? That will be damn loud i tell ya! I would put a small muffler in just to keep it down a bit.  I can understand why u would want to do it yourself, we charge around the $1100 to $1700 mark for full 3" stainless systems!! Nearly the cost of the Z18et itself!!! Hope this helps u.
