Bypass pipes installed! Now a problem?

[AndyA6]

Mods so far:-
UD pulley from RSS
Technotorque
Bypass pipes from Fabspeed

First the good news! Awesome sound and most def better performance!!!

Sound, deeper at idle and louder/meaner in the higher revs. no drone. At the same time not annoyingly loud, IMHO just right.

Power, def more. Before the mods I always felt a flatspot between 3 to 4,000 rpm. Now gone, very nice! Engine feels "lighter" if you can imagine that.

Installation was relatively easy, car on lift and the right tools did the job.


Also, wierd enough, the 3200 vibration is gone but I feel some at approximate 3500. Go figure! Somebody posted here that the 3200 vibe was gone as well after he installed the pipes.

Now a couple of points which are not so good.

First after 24 miles of driving the check engine light came on. Why?? Do I have to reset the ECU??

Have to check the exhaust alignment, I think one the pipes touches something.

Any comments and/or feedback please?

Thanks for reading!
Later,
Andy
