Competition Header Set 997.2 Turbo / 997.2 Turbo S - 3.8 L - Brombacher Edition

Description

Shorter length turbo headers tend to crack on cylinders 3 and 4. This is due to the shorter pipe length which cannot expand like a long tube header. The Brombacher Edition Header design includes a slip fit expansion joint which allows the cylinder 3 and 4 primary pipes to expand under high heat conditions and prevents cracks.

Our entire Brombacher line of exhausts is manufactured by M&M Exhaust, GmbH in Germany. They manufacture a multitude of Porsche Motorsport, Race Exhausts and Street Exhausts. Each system is tested comprehensively for exhaust gas scavenging, flow velocity, thermal stress, cracking, and longevity. M&M exhausts have competed in and won hundreds of 24-hour races over the years including Nürburgring, Le Mans, Dubai, Daytona to name a few. When you purchase these headers, you are the benefactor of all that Porsche racing experience. If you are looking for an exhaust product that can handle abuse on the street or at the track, look no further.

How are these headers different to the competition you ask? M&M manufactures in Germany and uses the highest-grade German V2A - X5CrNi18-10 - 1.4301 (T-304 L) motorsport grade light weight stainless steel. They start with a laser cut, stainless steel, dual plated primary flange which is more labor intensive to manufacture. M&M's race experience with thick, single plated flanges warping with age, heat and vibration lead to costly performance losses which prompted them to engineer a more reliable design. Their double plated flange allows for greater thermal expansion which dissipates heat more efficiently, which equates to greater reliability on the track or street. Next, look at the hand ported primary inlets, again, this is a more labor-intensive method, but hand porting means more laminar flow which equates to greater exhaust gas velocity and more performance. The inlets lead us to the equal length primary tubing whose diameter is selected and designed specifically for your engine's displacement. Each primary tube is mandrel bent, segmented and purge TIG welded by hand. For those thinking, why aren't the primaries a seamless length of tubing like some others in the industry? Segmenting strengthens the primaries and prevents stress cracks commonly found with the competition's headers. The primary tubing leads us to the custom made, purge TIG welded, internally blended merge collector. The collector then smoothly transitions into a larger diameter outlet for greater scavenging effect. The header connects to the turbocharger via a hand ported outlet with single plate 3 bolt flange.
