I was wondering if the Tanabe Medalian Exhaust - Medalion Touring 65mm would be OK to use with my Berk 70mm HFC? Thank you.

I love the sound.

It will be fine but a 60mm/63mm HFC would be better.

+1. FYI the exhaust is 60mm which is why the car in video has a 60mm test pipe to match.

You'll be fine. Any difference is PII ( Preoccupation with Inconsequential Increments).

There is no consensus regarding pipe diameters here. I'm convinced a near constant pipe diameter or at least smooth diameter transition keeps exhaust flow smooth. Different diameters make the exhaust speed change speeds. Like changing the diameter of your garden hose nozzle as a good example. Anyway I run the Berk 63.5mm high flow cat in front my the Tanabe Medalion Touring exhaust.

Unless you have dyno numbers or drag strip time sheets we're guessing at best and even those are highly dependent on atmospheric variables making more PII.

Let us know. Anyone running a stock exhaust will immediately perceive much more power from the Medalion Touring exhaust. I get weekly compliments still on mine.
