I will soon buy a Honda Accord Coupe V 6
2011
I wanted to know what the diameter of the piping?
Where can I buy an improved piping kit, can you get me a site?
I would also like to Ram Air Filter Kit which should bring?
You can get me links to things or where to look.

Thank you very much.

 

For a 2011 I would think there is not a link or performance anything yet out for those cars..SEMA show is at the end of the month..wait till then to see what comes out about the 1st of December.
I suggest you go to Honda shop and measure the pipes like any one else would have to do..
