Is this possible to do? Basically is there any sort of work around to tell the ECU that the cat is still there without it actually being there BESIDES getting a $500+ tune? I'm asking this question for a friend as she's interested in getting a catless downpipe but simply can't afford the price to properly tune it. Or does anyone know of an affordable HFC that can be welded into a catless DP that will keep the ECU happy? Any ideas or input it appreciated! Thanks guys!

 

Yes, get the can tool from BMS. It's only $120 or something. It'll delete the cel light but not delete the pending code.

 

It's actually $180 but still a good deal.

Or you can get the Akrapovic Delete-R for $275. Another good choice but more expensive and more difficult to install but I does not occupy the ODB2 port so it allows other things to be plugged in at the same time.

Important note: these options will not pass most emission tests.

 

Thanks for the replies guys! The first option might actually do the trick as for the second one, that seems a bit expensive since youre only an extra 125 away from a full tune lol. Akrapovic isnt ever the cheapest option however so I sorta expected that. Appreciate the help guys!

 

If you/she can't afford it, don't do it. Wait until you can save up the money to do it correctly.
