I will be purchasing a custom exhaust next week. It will be mandrel bent piping from accordinglydone and a Brullen muffler; if I can find one. My problem is I don't know which diameter piping to get; 2.250 or 2.50. I have searched and can't find a tread specific to this. Can anyone tell me the pros and cons of both to help me w/ my decision? I have a 94 EX w/ K&N drop in and removed resonator. My plans for the car are this exhaust followed by a cold air intake. Next year I will work on a suspension upgrade. That's it!

Also does anyone know a site where I can get a nice dual tip muffler. Something like remus, brullen, or ansa.

Thanks for the help.
