Customer Questions


Got a question pertaining to the j pipe. I wanted to purchase it but not sure which route to go as for race pipe or metal cat? Can you please help?


Sure we can. The Race Pipe will delete the 3rd cat, while the Metal Cat will replace it with a high-flow metal core cat.

While neither option is legal to change out, neither will result in an engine light and both will increase the power of the car noticeably.

The Metal Cat is a great option for reducing the smell and soot that can come from deleting the Primary Cats, as well (PCD).

Q:if i add the metal cat, this would be the replacement for my stock cat? is it street legal?

if ever i would buy a catback exhaust, would there be any problems regarding the attachment? i'm considering atlp or xlr8 catback exhaust..thank


Yes the Metal Cat is a high flow replacement for the stock cat. The j-pipe itself is legal, however adding a cat that removes the stock one is not legal.

There would be no fitment issues when installing this j-pipe with an aftermarket cat-back from ATLP or XLR8, as long as the parts are for the right model!


I want to do from the header all the way back . Do you have a header that fits to the j-pipe, then exhaust?


Your vehicle is not be equipped with traditional "headers." Before going further, we would suggest reading this article regarding the exhaust layout on your J-Series Engine equipped vehicle: An Outline Of The Exhaust Layout On J-Series Honda V6 Engines

We can provide a complete set of exhaust components from the engine to the tips, and will be happy to consult you on the needed items.


Is there a performance difference between Metal Cat and Race Pipe? If so, how much?


Very minimal...such as it would be hard to test and see a major difference on a dyno. But, for maximum performance, you would get a Race Pipe cat delete.

Q:Does this product come with all the correct hardware for it?

Yes, the ATLP j-pipe comes with all necessary mounting hardware and gaskets. Some kits reuse the factory hardware so if you are not sure if you have everything when you get your kit, feel free to contact us.
