Does swapping the mid pipe get rid of the secondary cat? Can it be swapped and leave the stock muffler?

if you go with the N55 mids yes you are deleting the secondary cats and retaining the resonator. OEM rear section bolts on no problem. its a great setup if you dont want to go louder or uber loud.

I was trying to avoid messing with the emissions system. I realize the secondary cat is after the last sensor, but if that is what it takes, I may do it.

It totally drones. Between 2.X and 3k rpm. I used to think the same way as you guys, "What are they talking about?". All it took was driving with the HK off and I could hear it for myself.
On the plus side, if it sounds that annoying inside, I imagine it must sound great outside! hahah |

This thread is not intended to continue a debate of whether or not there is a drone or not, anyone who does so is taking the thread OFF TOPIC.

By the way, how's the progress on your solution? Just curious. EDIT: When I said I agree, I meant the part in bold, as I do not believe my car drones. But I do respect and admire someone's dedication to finding solutions. Last edited by 1SerieStud; 02-13-2012 at 04:00 PM.. |

Well maybe some do and some don't......... but mine sure as hell does!
.... and I am going to install the N55 midpipe this week to see how it does re reducing "Du Drone". I might get a few more horses and a little more sound also... we shall soon see ! |

So, if that's the case the secondary cats section is responsible for the drone? Ie, no drone on the akra when the valve's closed?

THe whole system is a "little" deeper/ louder, but only slightly. I can't comment re any HP /torque changes. |
