Every one says its not a good idea untill they get a mid block or big block engine and then all of a sudden they can't keep they'r engine tuned, they then realize that there are no big block pipes t ocome out of hte rear of the revo. So what do you do? You do the following.
If you want higher rpms/ higher hp go Ofna JP-2 pipe
If you wnat more torqu and low end power go Ofna JP-1
If you want the best over all get the Ofna JP-3
Hears what i did for my sirio 23, wich was also bought for my next engine wich will be the Novarossie 528 or the Ninja 28 if its out by then.
