After checking out the above mentioned
straight pipe that looks like a catalytic converter, I read the disclaimer at the bottom. Hilarious!
"The product description above is for entertainment purposes only. This product does not perform the exhaust cleansing function of a catalytic converter in any way. Use of this product on or off the road violates countless laws and may prevent your car from passing emissions. It is unlawful to install this product in any vehicle in the United States, ever. If you wish to return this product at any time in the future, a full refund will be issued. This product should only be purchased by lawyers with pre-1975 vehicles or purpose built off-road vehicles that did not come with catalytic converters from the factory who know for a fact that it is legal to use in their vehicle in their jurisdiction for aesthetic reasons only. If you are not one of those lawyers, this product should only be hung on your wall to express your rebellious nature, never installed in a vehicle. This product may cause cancer."
