Hi all - 1st time here, but not a newbe!

I need to completely rebuild my quadzilla after a 4th gear endo, tumble and at least 2 1/2 gainer by a now very sore relative of my girlfriends. I need to put on a new pipe, and I was wondering if any body had any feed back. It seems the chocies are Trinity, FMF, and DG. Any experience with these? Any other suggestions?

I ride in the dunes only, Pismo, Oregon Dunes and Glaimis for the 1st time next month!!!

Thanks fo any help...

90 Quadzilla 530, 97 Banshee built, 96 Banshee stock, 97 Blaster stock and last but not least, 97 Toyota T-100 (The T100 ALWAYS draws a crowd at Pismo)
