N54 Downpipe Fix

harrisontjo · 01-09-2023, 03:04 PM

Does anyone know where I can buy a DP fix from for my n54. If not does anyone have one they could sell/lend me?

Have you considered running MHD? It "fixes' the DPs for you.

I need it to pass emissions where mhd just disabled the catalyst system and you cant pass smog like that

Sounds like you have some different rules than we do up here. The tune's fix solves it for Massachusetts.

Good luck.

Can you put the stock DP's back on...get it inspected, and then put the aftermarket ones back on?
