Are you f---ing serious with the all caps, what is this 20 questions here. Easy on the caps and for the love of God please take some time to spell correctly. I car hardly read what you are trying to ask.

Buy the freakin muffler and go to a muffler shop and they will put it on for $50. Case closed.

CHILL THE F**K OUT DAM I KNOW I CANT SPELL THAT GOO I MEAN SHIT

If you are trying to have a catback that is larger than the mufflers 2.5" you should definitely buy a mufler that has an opening the size that you need. Unless you are turbo or are going that route shortly 2.5in will be the biggest you want to go. If you go any bigger you will slow the exhuast gas velocity and lose too much bottom end. Instead of getting the muffler shop to bend piping for you you should get the pacesetter catback from nopionline.com or howellautomotive.com and just use the OBX muffler instead of the one that comes with the system. It has 2.5" mandrel bent pipes, versus press bent piping that the muffler shop will most likely use, and the muffler will weld right up to it. Evulflea wasnt trying to be an ass, its just easier to read things that arent completely in caps, plus just take the time to read over what you wrote by utilizing the preview option. If you have any more questions feel free to ask.

oh, and besides the piping and muffler you will need hangers for the system. You wont need to purchase the hangers though, they can do that at the muffler shop

thankx alot sorry if i pissed you off your a great help thank you again
