I was wondering if anyone had heard or had any experience with the Pro-Curcuit 400 ex or the White Brothers R-Series. My choices revolve around the FMF, Pro-Curcuit, White Bros. R-Series, Big Gun and maybe a Double Barrell. I plan to race, but i also ride on wooded proctice tracks and in the local trails. Any help is greatly appreciated.

 

I have the BigGun on my 400ex. It is a nice pipe. It has a good fit and finish and looks nice. However on the head pipe it does not have a heat shield I dont know if that would be a problem for you. It is also quieter than a DG I had on my 250x race bike. I like the Big Gun and I think the neighbors also like the queiter sound..

Griff's FSR

 

That R Series exhaust looks really nice. I was going to run that or Bill's Pipes. Since the price is right, I'm gonna get the complete Bill's system in a few weeks. I'll post my results later.

 

I have had a Big Gun and A DMC the Gun makes more torque but The DMC revs a lot better. DMC is the way I would go again Incredible workmanship.
