i am thinking to get bonez downpipe and high flow cat and hks silent hi power exhaus
the cat is 2.5 inch and the exhaust is 75mm
do u guys think this is gonna be a good combination?
an exhaust shop should br able to make them custom fit.
is it gonna be viable or should look for different set up?
im looking for something reasonably quiet for street driving on my tii

 

did you ever find out if it fits? i have rb headers and bonez cat and would like to run a hks silent power too
