Does anyone please have any comparison pics of the 2 midpipes, side by side if possible as I have yet to see the N55 midpipes in question.

Also part no is 18307599743 sound about right?

Was quoted £289.43

Thanks mate

Drillslinger · 02-22-2012, 12:57 PM

Are there any performance benefits to swapping them out or is it simply to reduce the drone?

Thx

Aussie_in_London · 02-22-2012, 01:55 PM

Removal of the 2 secondary cats will aid in flow and back pressure .

And give you a small bump in HP - me thinks.

Tuned1M · 02-22-2012, 02:04 PM

Between the rear muffler and mid pipes you're going to pick up the most gains from changing out the mid pipes.

ozinaldo · 02-22-2012, 04:51 PM

Can we mate the N55 midpipes with the Evolve exhaust w/out any mods or so? If so, would it end up with similar gains or maybe Evolve/Supersprint already managed best possible solutions in terms of eleminating the drone while increasing the power and enriching the sound by using the stock 1M midpipes?

clived · 02-22-2012, 05:16 PM

I think the answer to that quesiton may be coming fairly soon ;-)

Fitted my N55 mids last week..15 min job..easy as.

Deeper, meaner sounding exhaust note with a nicer burble in downshifting..

I have never really had any drone, so no comparison to make in that regards.

Deff more torque mid rev range 3.5K rpm and up in 2nd and 3rd gears.

Dynoed before install and will dyno again next week for comparison.

Aussie_in_London · 02-23-2012, 03:59 AM

Nice to hear mate, will for sure order it in......looking forward to your dyno comparison.

Twinsturbo · 02-23-2012, 01:30 PM

Anyone that knows of or has an video of the 1m oem system with only the n55 mid from outside the car? Noticed that einserm on the forum had a video on youtube but it's from the inside..

Zuzu · 02-23-2012, 07:36 PM

If I have time, will do one this weekend.

I'm subscribed for dyno results! Tx.

Here is a cold start in my garage..Stock 1M with N55 mids.

Will shoot a drive by tomorrow and post.

Watch in HD

Zuzu · 02-25-2012, 02:51 AM

Now hot start up and take off.... and a perv at my awesome wheels..

ozinaldo · 02-25-2012, 10:01 AM

Thanks Zuzu, gives a pretty good idea of the sound your videos. Now, the test and dyno results from Evolve is the only thing missing.
