As far as custom shops go, you have to make sure they are mandrel bending the piping or it would be no different than going with a smaller diameter pipe since all the crush bends would lower the diameter.

I will be changing the Y pipe later on to something bigger for sure. Because from the Y pipe back it's going to b a pretty straight pipe going to the back with a little curve to the HKS muffler and out. There is going to be a lot of free flow therefore, I was asking to see if a none boosted car would actually lose power that way or not?
