I haven't dyno'd it yet, but you definitely feel the low end hit much harder.
The downpipe was installed without the JB4 at first. I did about 5 days of normal driving on just the downpipe (without Jb4) and felt a very large noticeable difference. The noise as well is absolutely intoxicating with the MPE! The downshifts and letting off the throttle just gurgles like crazy. The drone is non-existent for me which is another beautiful thing. I absolutely love it I couldn't be happier. The smell is also non-existent, I don't know if it's just my nose used to the smell. I used to drive a N54 with downpipes prior, so I was used to a bit of a smell... No one has gotten in my car and said "what is that smell" so I guess that is a good thing. With the JB4 installed, I could feel a little bit more of a difference in the low end but very little up top. Is it worth the $500, yes. Is it like the N54 where is absolutely changes the vehicle every-way possible? No. So far so good, I love this car.

No check engine light while driving without a tune. I believe I drove actually for about 8 days, since I had to wait for a new harness from Burger. I was very surprised the CEL didn't illuminate.
Still no CEL to date.

Im doing the same mods this weekend, but i was wondering what map are you running? You didn't get the N55 JB4 EWG Harness Adapter did you? Don't see it in your pictures.

The harness wasn't out when I had ordered.
I'm on Map 2 I believe. (The original map)
