Question on the yosh exhaust insert

Recommended Posts

I just got my exhaust today and it already has the spark arrester installed. My question is if I remove it will there be any power gains? If so where is that power gained at and do you lose any?. I have heard it will make your ears bleed if you remove it.

I doubt it's a spark arrestor, if it's an RS4 system it's a db lowering insert. Much of the dyno work I have seen seems to imply it's good to leave it in there.

My RS came with a sparky already installed. I took it out

When you removed it did you reinstall the aluminum ring once you pulled the mesh screen out?

Danny at Yosh told me the quiet insert that comes installed produces the most power on their dyno tests.

Did it have the stainless mesh screen attached to it?

Order the 99DB insert from Yosh, use that for best performance and its not to loud.

That said, the new FMF RCT is the better system as you can remove their insert and get a nice bottom gain over the Yosh and its not to loud at all.

Id send the yosh back and get the FMF.
