Making a custom exhaust silencer for the BMW M3 track car to pass noise regs.

Рет қаралды 27,244

The new exhaust I made for my BMW M3 ended up too loud for most UK trackdays. We'd made a temporary solution, now it's time for the real thing. Jay makes a completely custom exhaust silencer from scratch & I drill a hole in my DCT gearbox.

Cutting these tubes at angles is quite a bit of fabrication so I’m going to make a whole box from scratch. That’s the most Phil thing hahah

@tonistaru 3 жыл бұрын

Judging on how the exhaust interacts with the subframe at this point it would have been easier to just tube chassis the whole car.

Haha 😂 My exhaust is difficult. I know, I'll chop the back of my car off and tube frame it 😂

Stainless steel wire wool is commonly used to pack around the perforated tube first then fiber glass packing… slows the loss and burning of glass material. For next time 👍

@pinderwagen 3 жыл бұрын

If instead of a square, the centre of the adapter was drilled with a taper, you could just fit a countersunk m8 bolt. Would have saved you a LOT of effort. No idea why they don't make it like that, there's enough material. Did you do a phone dB before and after test? Nice job on the silencer 👍🏼 with the extra one in the van, even if you do ever fail, you know you can quickly bolt that on 👌🏼
