Another Exhaust Question

I went to get new exhaust for my 05 wr450f and I was thinking about a Big Gun system, but have not read very many good responses on that so I said no thanks. The shop owner then told me that I should go with a ProCircuit T4 system and that with a Yamaha you need to replace the head pipe as well. I'm not worried about how loud it is, I DO need a spark arrestor. I mostly do some local desert races and enjoy trail riding.

Any help would be great...Thanks

I like mine

You like your Big Gun pipe? Did you do a header pipe as well?

I have a Big Gun on my Predator w/a aftermarket rev bax and I made a huge difference.
