    Magnaflow 14815

    I have been searching but haven't really been able to come up with a definitive answer so here is my proposed exhaust setup:

    2.25 inch Y-pipe in and out to 2.25 in Magnaflow High-Flow CAT and then 2.25 inch tubing to Magnaflow 14815 muffler. Would this be too loud or?

    Is there a way I can do 2.5 inch? I know I can get a Y-pipe that's 2.5 inch and a Magnaflow High Flow CAT that's 2.5 inch but I can't seem to find a 2.5 inch muffler. Are there any and if not what have you guys done to cope with the 2.25 Magnaflow 14815?

    I am making these changes because my CAT is currently swiss cheese and the rest of the exhaust is a mess as well.

    Thanks in advance for your help.

    the 14815 is pretty but it's going to be loud. IMO I would build a 2.5" system with a high flow cat, a resonator (or second muffler) and a different 2.5" in/dual out muffler. if you just have a cat and a single muffler it's going to be even louder, and a single 2.25" may actually be a downgrade from stock.
