Very nice work, you are doing all the things I have dreamed of doing to mine. (So close to just buying that HKS exhaust.)
Did you happen to replace the turbo elbow and down pipe as well? I have the BIC DDP, but I don't know if I can ever bring myself to install as I want to stay as stock looking as possible too!
By the way, in case you were wondering, this is what your cool NON SMOKERS BOX says:
(Translated a bit literally for fun.)
Notice (This more literally translates to "please" in Japanese. All part of the politeness.)
1. This item is not an ashtray.
2. Please do not use for anything other than the storage of small items.
In case you want to have more fun with Google or other translators: (It really flubs up the second line!)
お願い
1.本品は灰皿ではありません。
2.小物入り以外には使用しないでください。
