Operation stop the rattle and free the ponies has commenced.

I have always been a little dubious about my h111 signature exhaust backbox since I got the car for no other reason that its twin pipes and I prefer the asthetic of a single larger pipe.

Tonight I decided its time to go so it did, but not without a fight!

I couldnt help but notice a little rattle ...




Ill package this exhaust up and send it to a tame exhaust maker to template and see what we can do ..

Always good to find a problem (in my strange world).

Can we chop it open yet for a look?

I have been working with a chap to get a custom exhaust made to spec. Mark has been great with the communication and ideas.

We have now two boxes in the system and the smaller box is easily removeable via vband.

Here are some images :

This leaves a quite subtle stubby single pipe poking out which I am delighted with. The slight off centerness is down to me being 25mm out with a measurement. I swear I wasnt drinking when I measured.

I have only started the car up once for a few minutes as it was late and the tone has changed dramatically. I now have bass! The only way I can describe the previous H111 exhaust is like a surround sound system without a sub. Vocally its there but there is no drama, no rumble! Its there now.

Cannot wait to get out to "test" the system and booked into the dyno to see whats what with the fuelling. Thats on 17 FEB 22. Not chasing numbers but something was restricting me last time ...

Looks a nicely made exhaust silencer. What was your reasoning behind a twin can over a single can?

Really would like to hear it on tick over, blips and running :thumbup:

Quietness. I don’t want any noise hassle on quiet tracks.

My c63 was my shouty phase. This is my ninja phase.

You could always swap the small can for a straight section for hooning around xxxxxxxxxxxxxxxxxxxxxxx xoxoxoxoxoxoxoxoxoxoxo

I have driven 90+mi in the car since Friday night. A combination of local driving and a bit further. I must say from the muted sounds that are in the cabin it sounds 1000 times better. It 2ZZ is never going to be more than a high revving 4 banger but I quite like the sound.
