Can anyone reccomend an 80mm test pipe?

I wanted to run a Blitz downpipe with a Blitz cat back exhaust. They are both 80mm and the only test pipes I've seen are 76mm. I know there's not a big difference between those numbers but I think it would be cool to have a full 80mm set up.

Any info/feedback would be great!

 

Get it custom made if u can't find one. There's nothing to it really. Just a pipe with flanges welded to the ends. Check out Speedymetals.com. You can purchase any metal in any quantity you desire. It's pretty cheap.
