I agree, but I think everyone is going to want to hear why you think so.

 

Yeah that is a waste of money. Buy a cheapo test pipe off ebay and do the spark plug anti-fouler method.

 

or they could just extend the bung for the o2 sensor instead that dumb mini cat lol....they obviously didnt spend alot of time thinking about this test pipe

 

It is no mini cat. It does not clean the air. There is way too much work involved in this part for the result of cheaper proven alternatives as mentioned in this thread. The price point of this part is excessive compared to other units in the market.
