Quads with Magnaflow mufflers?
So the inlet/outlet size of the magnaflow muffers are 2.5". What if I were to put quad tips in place with an inlet size of 2.25"? I know that an exhaust shop would use a reducer to install it, but would this affect performance at all? How about sound? Would it just make sense to get quad tips with an inlet size of 2.5"?

Yes, it will affect power. Air flow = power, thus, reduced air flow = reduced power. Air will only flow as fast as the narrowest part of the exhaust will allow. This is an extreme example, but makes the point nonetheless... it doesn't matter if you install 4" pipes throughout your system, cuz if you have bend or any point were it reduces to 2", the entire system will only flow as efficiently as the one 2" section will allow. That's why mandrel-bent piping is always better, cuz it keeps the diameter of the pipes consistent over the entire bend. Unfortunately, Mandrel-bending isn't typical practice for custom fabricaters. Traditional pipe benders (which is what most shops use) essentially pinch the pipe at the bend's apex, thus reducing the actual size.
However, if you got a Y-pipe with a 2.5" inlet and dual 2.25" outlets, that would work fine. |

Aftermarket exhaust is mandrel bent, standard. Most higher end car companies do from the factory as well.
OE replacement parts, and stock corrolla / civic pipes, would be crimped. |

what quad tips are you looking at? My Mtech rear bumper is enroute to my bodyshop of choice. I think a custom Magnaflow quad setup will follow shortly after.

You could just get a muffler with a 2.25" inlet and outlet if you want it to be the same.... |

I figure material and labor for that cant be more than $150 at a decent shop. Also, there aren't too many bends there so crushed bent it fine as far as that is concerned... |

I think we are misunderstand each other. I bought Borla cat delete pipes to get me from the DPs to the rear of where the secondary cats were. Then I bought magnaflow mufflers and tips. All I need a shop to do is bend 2ft of piping for each side and weld them up....
