Not really "considerable" IMO, but you will definetly feel the difference. The freeflowing exhaust allows for a quicker spooling turbo and the ability for a bit higher boost levels . Torque feels stronger for sure. Now I have to start researching for a clutch since it started slipping

Pardon the video, I really need a better camera.......

Would it be a better bang for your buck to purchase N55 mid pipe rather than berk, Maddad or cp-e mid pipes? My exhaust system is completely stock.

If you have a good exhaust shop near you have them delete your rear cats and put straight pipes in or for a mOre silent option,use vibrint resonators.The bend on the left rear cat SOS tricky ,so get a quote first before they start..I saw a aP mid for sale in the for sale section,you should offer him a deal on it..If I didnt delete mine ,I would have bought it!

It depends, the bend on one of the cats are a bit difficult ..One shop wanted to charge me $375 with materials and tig welding ..I respeat don't go to Midas or any other bullshit exhaust shop..I fair place should charge you $250 max!! The turbo will whistle extremely loud after this mod,Mini dump turck sound alike .lol

as far as the smelling issues, you wont notice any unless you also remove the primary cats as well. There is always a small HP gain when you make an exhaust less restrictive but nothing to really brag about

holy crap, what a rip off. I am running the N55 midpipe connect to a custom 3" muffler delete, I only paid $325 for everything but I got the midpipe from a local member used

I have the Berk Exhaust on my 2009 135 and am considering getting this N55 midpipe
Will it fit on my stock downpipes ? I assume it will since it's a stock part ?

Thanks for the video, it really tempts me lol

for 377.80 isn't that a much better deal than even the Berk midpipes which are 599 ?
What are the differences ?

This is where I'm at too. I want either a Maddad midpipe ($649), Berk ($599) or OEM N55 ($377). Obviously, I know the price is the main consideration if they're pretty much all equal in quality, fitment and free-flow. But that's the question, are they?

Make that three. I have n55 mid pipes (obviously) and like the sound of the Berk Sport system, but would rather skip the mid pipes as it would be much more affordable. I'm just concerned about sound and restriction.

Get the Berk Exhaust and BMS dual cone intake
Sounds subtlewith exhaust and you also hear the Turbo spool with the intake

[startover]

Is there any advantage/disadvantage over cutting off stock mid cats vs N55 mid swap? My assumption is that cutting will actually give it less of a stock look since the N55 is OEM?

Good question I was about to ask that too.

[icabod7]

OK this is my opinion, and remember its only that -- the Maddad is in first place now because 1) they actually show dyno numbers with HP increase; 2) their exhaust fitments are spot on (you rarely see any complaints about quality and fitment of Maddad on this forum); and 3) it tries to retain the OEM look.

Counterpoints?

If you can get it done for $200 then do it if not I rather buy a berk mid with the bigger piping and maybe squeeze out 5 whp
More ..

[thebigragu99]

All the gains are from removing the rear Cats in the mids!

Removing any emission equipment from your vehicle is never legal, neither is catless DP's but that doesn't stop anyone from installing them.

N55 has two cats built into one in the DP, plus it is a much cleaner burning engine, thus no need for secondary cats.
