Also we now are the number one distributor for BMC filters for the USA E9x M3's. The high-flow sportcat is constructed from 14-16 gauge T304 stainless steel and we only use German imported 200 cell per sqaure inch sport catalytic converters. No Check Engine light and this is save for emissions and inspection. P.M. for 6speed discount or you can email Joey@fabspeed.com for a quicker communication line.

Is that a resonator on the second pic? It looks like the HFC's are where the primary cats are?
Any gains with just the secondary cat delete?
Also, is the tubing the same size as stock? It looks a little smaller?? Thanks.

[Sercan]

If you guys don't mind me asking. What's a rough estimate of how much time and money you put into your cars ?

AUS yes that is a resonator in the second pic. We manufacture the X-Pipe with resonators to keep the aggressive tone at a "tolerable" level this way there is no drone inside the cabin. We also have a primary catalytic converter replacement with our 200 cell HJS high-flow sportcats. With just the X-Pipe you will increase power by +16HP and that is with the stock muffler and stock catalytic converters. All the tubing is the same size as stock. Our X-Pipe slides over the existing stock tubing and utilizes the same clamping feature as the stock secondary catalytic converters.

Joey@Fabspeed,

How much peak power are we talking about for all 3 items installed? Is tuning required to maximize the gains with any of these mods? Thanks, and if you had a dyno chart to share, that would be fantastic.

Steve with all three products installed (Primary Sportcats, X-Pipe, BMC Air Fitler) power increases by +22HP

With those products installed and an ECU tune power increases by +32HP.


Just to clarify, these graphs are from two different M3's. The last graph with the ECU tune already had a crank pulley and air filter installed prior to our products. The first graph only had an Eisenmann muffler installed.
