Guys,

Forgive me for insisting with this one...
I posted the same text in an old thread, but maybe everybody is tired of it and not reading anymore. I would really appreciate your feedback about this

I have this QD exhaust in my 1100.
I'm not a very big fan of loud pipes, so I kept the db-killer. But I had allways the impression that this db-killer could be very restrictive...Even though it is a straight open tube, it has only 26mm of ID...
Can this create overpressure in the exhaust system?
Thanks guys

Leave it in. Any performance gain will be so minimal as to be unnoticeable. It may [i]feel[i] faster because it's noisier but it won't be.

What Pete said……
My MIVV pipe has about the same ID exhaust exit….
Runs great with a Beetle map

Thanks guys. I will keep it in...
It"s just because I had recently to repair exhaust leaks and I started thinking I could have too much pressure on the system.

Exhaust physics is not simple.

I've given up arguing with the 'Loud Pipes' brigade. It's not worth the craic.

What Pete said. You need a PhD in Fluid Dynamics to truly understand exhaust gas flow.
Your 26mm port is perfectly fine. The 29mm port in the exhaust of my 1400 GRiSO is fine.

I have used the Mistral Hi with and without the db and also the Termi with and without. My thoughts are that yes I love the rumble but definitely feels flatter and uses more fuel with it out. I say leave it in.

Hi Whitmire,
It's crazy, isn"t it😁?
A touch of gasolina fragrance and it would be 👌...
