Thinking about a custom 3" exhaust

Not sure why you would do a stock Y and 3" back. You would still be restricted at the OEM y-pipe.

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.

Looks like your in Glendale CA. Fast Intentions is the way to go. If you are in CA, take a little ride & go talk to Tony or give him a call, He really is the man & you aren't going to find better quality or service. He's too close not to look into.

And yes I know Tony and will probably go to him also before I make my final decision but I wanted to know for sure if my idea of the 3" single would lose lower or not.

To answer your question as bluntly as possible, yes, you will lose lower end torque and overall power by going with a 3" exhaust with no forced induction.

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?
