125-200cc Best exhaust system for CR125

Hey guys just wondering what the best exhaust system (silencer and expansion pipe) is for the 2013 CR125. I was talking to Dad about it and he said he read somewhere that the stock silencer is the best, anyone confirm this?

I'm looking for a bit more bottom end grunt, so i can (try) to attempt slow wheelie's instead of doing them in band.

We love the Scalvini.

Wallets not so much....

I personally really like PC. Fits extremely well, looks good, sounds good and most of all not overly expensive.

I've also had FMF on my 09 and what a pile that pipe and silencer was. From the day I got the pipe and silencer it did not line up at all, it leaked coming out of the head and always had to be siliconed to seal it up. I feel like because the bike is an off brand they didn't seem to realy care to take the time to make a good fitting pipe and silencer.

That being said it could've been the luck of the draw and I just happened up on the short end.

I think FMF is well known for their quality control, or lack thereof. I can't argue with the power though. It does make good power, and is much better off the bottom.

I've got the Husky/PC Racing "Factory" pipe and fresh 304 silencer for sale if you want to try it.
QC issues aside, the PC pipes are known to be more top end, the FMF Fatty also and the FMF Gnarly more bottom and mid.
I have FMF TC2 spark arrestor and stock pipe on mine and it pulls really clean off the bottom.
