Stillen exhaust and shifting issue....
 

I've had my Stillen CBE/HFC/G3 intake for less than a week and I've been having some weird issues with my M6 and shifting. This really didn't happen before the bolt ons so I'm going to assume that they are causing the issue. What's happening is when I am coming up to an underpass or tunnel or even a narrow street or road with tall buildings regardless of what gear I'm in the car seems to shift to a lower gear. The strange thing is its a manual and I'm pretty sure its not me doing it. Well I might be helping it a little. OK well its more of an insatiable urge to down shift and romp on the throttle to hear the exhaust note. Is this normal? Should I take it to the shop and have it checked out? Did I mention I love this exhaust? That's it I'm going out to map every underpass and tunnel in town. Time for some more data collection ;P

LOL! +1 rep

haha lucky boy!

Just got mine added today and :iagree:! I'm loving mine, too. Unfortunately my Z is an automatic so I'm not sure about the shifting issue.

Well then 2theextreme I suggest you go out for a burn and find out if there is an issue ;P

Man I really though you had issues lol! You had me going there for a sec! Points for you bro!!!

I think my aunt would say no.....I let her drive the car this evening. She needs to buy me a tank of gas now! :roflpuke2:

weired i have somwhat identical problem but mine seem to stay and stick on 2nd or third a block before coming to a tunnel or underpass and then it stays there and as soon as i hit the tunnel/underpass entrance the car seems to speed up and stays in gear to redline

its odd ;)

:rofl2: I love it.

Not gonna lie.. you had me clicking feverishly to get to the post.. internal monologue going 6MT WTF??.. and the realization I had been had..

That was an interesting 10 second rollercoaster!

Well played sir!

Your automatic has paddle shifters, and is also very susceptible to the underpass downshifting issue, trust me :tup:

We need videos to prove it to believe it! :icon17:

You should also try doing this in covered parking garages to see how many car alarms you can set off. It's one of my favorite past times. ;)

Wow, at first I was like really?? Sigh... need to start modding sooon...... >:(

I found a great two level parking at one of the Malls in town - man is it loud in there. No alarms set off yet though ;)
