E34 M5 exhaust options

[rick540]

I need to replace the factory exhaust on the M5 as it's reached the end of it's life now.

BMW OEM exhausts are very very good, so good in fact I'm worried I will get a power loss if we just "make one up"

Any ideas?

You wont lose power if you go to an exhaust place that knows what they're doing

Could you not duplicate it exactly as is, with equiv part numbers from bosal and or.. ?

You cant go and buy 92,000,000 for a BMW exhaust

I would use TNT and tell them to make it the same as the oem one... are the branches fine? the top looked good from the pics i have seen...

Well I would need a loan to buy an OEM one and I wouldnt out of principle, it's something like R40K +

BMW did a right number on this thing I couldn't even begin to copy, to start it's like 76mm pipe that not many machines can bend, and there's two triangular mufflers to fit in the tiny space then a really giant L shaped muffler and then a rather large rear box that's also shaped.

I wonder what kind of patchwork repair I can do or get done.....

I know there are guys here in SA that make mufflers to any shape by cutting and welding stainless steel, but I don't know who they are.

what a mission... i know someone who can bend mandrel bend 76mm but its going to be a huge mission to get this done...

i would patch the boxes if possable... can you weld?

Well that would be the other thing, it's double skinned, but we will certainly try and see what we can do.

Rick my dad got a new exhaust on the E60 525i from BMW.. came to Just under R50K.. So for a M model i am sure its going to be more...

 

[moranor@axis]

i would just patch it for now and look into making a new exhaust...

this way you can take your time and do it right...

Eisenmann seems like a popular choice. Maybe a little loud though?

Ask AJM what they did with his car.
It sounds fantastic
