ok so on our sedans has anyone tried just changing the tips of the exhausts and is it possible. i tried searching didnt find anything. on ebay i saw this http://cgi.ebay.com/ebaymotors/Infin...Q5fAccessories
but i have no idea how i would put it on is it a simple bolt on or how does htis work. any info would help.

 

I just changed my tips, cut them off and welded new ones on. The link is too a whole muffler.

the inlet should be 2.5 right? and how hard was it to install. you said you had to cut them?

 

and where did you buy the tips for your exhaust??

 

Got them from magnaflow 35121, You can't install yourself, unless you have stuff to cut off the old tips and you know how to weld on the new ones.
