so ive been searching around too see if anybody is running a yonaka system with a turbo set up?.. but havent found anything. so my question is, is anyone ran it before? i know its kinda on the smaller size about 2.5 inch piping and preferred would be 3.. but im on a budget and its cheap and i like how quite it is. is it too small to run on a 300 hp turbo set up? with a 3 inch dp? i might just have to get a custom 3 inch at the muffler shop..
