do you have the kit yet? kuz i have one for sale at a very good price. PM if interested.
or if you know anyone interested. thanks!
^^ and too answer your question, get anyone muffler you want, the opening on the rear of the back ground effects, are the right side, and can probly fit one giant muffler through it, (if you wanna be like a honda) but if it does stick out past it then get on a welded extention.
another good thing to invest in is the Monza Exhaust.
and i would have the kit on first kuz if your dont then you may have to bend the piping in the process of putting on the rear kit peice.
