Just got the replacement pipe for my 300D california edition from ROLLGUY. Fits perfectly, great quality. I recommend anyone with a california 300D to get this part. Eliminates the worrisome oxide trap waiting to release metal bits into your turbo. Makes turbo more efficient and responsive. Also if your starter goes, you can replace it with a 49 state unit which is about $400 less than the CA part. Cleans up the engine bay a bit also.
