The downpipes and flanges are machined from T-304 high-grade stainless steel and are tig welded in house to deliver the best quality. 
Will fit the following models:07-10 BMW 335i 3.0l Twin Turbo E90 E91 E92 E93 (N54 only)
BMW 135i N54 3.0l Twin Turbo (N54 only)
 
The downpipes will provide a sharper throttle response due to faster spool of the turbo.
 They will provide noticeable power gains and a much more aggressive exhaust note which sounds truly amazing.
 They produce lower temperatures and less exhaust backpressure due to the relief of the turbocharger.
The cylinder charge is increased which generates maximum performance.
There is also a substantial weight saving in comparison to the factory catalytic converter.
The decats are mandrel-bent for better gas flow and maximum internal size to ensure ultimate performance without the loss of mid-range torque.
We have tested this product and found increases of around 30bhp.
The kit will come with gaskets and bolts.Professional installation is recommended as some exhausts sit slightly different from others and can be tight although the feedback we have received from this product is that it is very easy to fit.Please take a look at other items as I have many other performance upgrades for these models.
