I've got a buddy who's thinking of purchasing a FMF Fatty pipe for his Pred-90. His family does strictly trail riding (just like my son) and he does less then 20 MPH. He's looking for more bottom end power without a high reving engine. Besides that, his financial situation is very limited. Gee, his family sounds just like my single income family of 5.

Anyway, can you tell me if the FMF Fatty pipe will bolt directly on without removing its Oil Injection system and remove of its battery. If you have an FMF Fatty pipe on your Pred-90, please tell us the pros / cons from your perspective. For strictly trail riding, would you select this brand of pipe again?

thanks.
