Re: Loud Backfire sound from Sebring Z4 xos

Sorry for the OT Valor... all phil's fault. You can ask him to arrange the bbq to make up for it.

I can hear my stock one backfiring... very very slightly...

Re: Loud Backfire sound from Sebring Z4 xos

that sound rocks. std exhaust u normally dun get it...cos the cats n the big air flow muff will clean off any unburn fuel. after mkt exhaust always smaller, lighter...n doesnt restrict back pressure....hence u will get unburned fuel detonating in the heat...thats how u get the pops. mine sounds like mega lao sai on some days....

*gives toto a plug*

Yea, I like the sound... I was a bit unsure about it at first, but grew to like it. It's intermittent though.

Valor, there is absolutely nothing wrong whatsoever. In fact, to me, it means you have a healthy engine.

Re: Loud Backfire sound from Sebring Z4 xos

Thanks Phil, Summer & Toteseow, very much appreciated !!!
Like summer I was kinda worried/unsure about it as first but now at least I know it's not due to a damaged xos system.

Now Phil will plan for us the BBQ & bring all the food & drinks .. Summer say one
