Ok, I'm gonna have my exhaust fabbed up this next Tuesday, and I'm wondering if ti would be worthwhile to go ahead and buy some Magnaflow high flow cats to go along with it? Currently I have 2 14" round maggies, x pipe, and 2 18" 3.5 tips with 2.5" piping throughout.

Pretty standard setup for a true dual and all, I'm just curious what the difference is in having high flows?

 

High flows will make it flow better and be louder!

Get your stuff that you have now done first, then give it a wseek or two & if you decide you want it a little louder, get the Hi-Flows.

 

Like DarrenWS6 said do you mufflers first and see how you like the sound. The high flows will make it alot louder
