Default Secondary cat bypass DIY -easy peasy

So, while I was waiting for my air intake parts to arrive, I made another quick video which you can watch on my YouTube channel: https://www.youtube.com/user/12shoes2
Hope you like it and please subscribe to be notified about the Big Air for the Boxster part 3!

I'm not being "Catty" but what is to be gained by eliminating the secondary Cat?

Lose about 10 lbs. Improve exhaust note. Small power gain.
It's easy to do and compliments the intake mods that I am also doing.

You'll pick up more power/tq along with a deeper, throatier exhaust tone. Secondary Cats are restrictive and redundant and since they're not monitored/read by the ECU, no CEL.

Nice video James
