Hello guys, I wanted to connect to this discussion, why? I recently mounted on my 159 1.9 150hp jtdm q-tronic a downpipe and a straight pipe with cat 200 cell magnaflow in place of the DPF and made do, of course, the necessary changes to the ecu closing the DPF and EGR without? no the MAP.
Reading the various forum opinions on the downpipe are discordant....who says a loss in the low significant....instead, those who improves in low and others that don't change anything, but in my case I can assure you that shooting in low ? increased greatly!! When starting from a standstill with the qtronic I always had a lag incredible why? before 1500, the turbo didn't want to enter but now I have a linear progression from 1000 rpm, another car, that's it. Fuel consumption is also improved significantly......smell it for? ? increased, but no smoke thanks to the CAT 200 cell

The only thing that is most noticeable with the downpipe ? the whistle of the turbine, which now feels more out from the exhaust....if I put a terminal sports do you think the sound will improve??

if you put a terminal sporting a little bit improves the sound but little,for the downpipe definitely improves the bass.

The improvement at low revs you can feel how you mount the downpipe, only with the dpf off the difference ? little.
I am talking about the 2.4, 1.9, even with the downpipe the difference ? minimum.

the downpipe is a straight tube of stainless steel with flanges in lieu of precatalizzatore.
