No in fact Fabspeed DP and HJS DP are two different products, even if Fabspeed use an HJS 200-cell cat in its DP.

I've a HJS catted downpipe on my M235i. I was in the first batch to install it in july last year.

I review it HERE at 2addicts.com

I always use 98 petrol quality.

My car has the following:
- M Performance exhaust
- ER Turbo to IC and IC to TB charge pipes
- GFB DV+
- Wagner Evo 2 Competition IC
- HJS Downpipe
- Stock DME (No flash tune nor piggy back)

All gaskets/clamps/seals were changed at each hardware installation.

I didn't have any CEL during nor error codes for +7000km with it, that is to say until november 2015. Then it started to generate P0420 errors.

In fact the trouble is that my car was updated at dealership to I-Level F020-15-07-506 in 10/2015.

So I don't know if this have an impact.


HJS exchanged my downpipe in January 2016. They examined my first downpipe and they didn't find any issue. They claim then to have it installed in a M135i without any issue...

I didn't have any error code nor CEL until April 2016... So 4000 km after second one installation, it started to generate P0420 errors (without CEL)..

This week, due to difficulties to fill gas, I mainly drove in Eco Pro. Then on top of soft P0420 codes, it finally triggered a CEL for the P0420 errors.

When P0420 errors are generated, it's at low engine load. Eco Pro is then the worst case...

I reset DME adaptations. We will see if P0420 errors come back...

300 cell is the only way for reliable no CEL operation it seems.

Makes me think going for one of the cheaper 200 cell downpipes with a JB4 might be the best way forward.

I know the obvious implications and differences between a box and remap, but can't a remap not map for a sports/decaf with no errors?

Correct the 300 didn't work.

I'd suggest going for a decat and putting the money towards the JB4
M135 LCI, Alpine White, Coral Leather, MPE, MP Decals and lots of gloss black - GONE
