Which Catless Down Pipe for my N55 E92 XI?

j2m · 08-25-2011, 02:30 PM

I have been reading all morning about these Catless DP's. Looking at Berks, Vishnu & AR.
Gets confusing after a while...
Any recommendations would help.

AR design

fitment is perfect

Vishnu's 3.5" is the perfect size for maximum tq throughout the power curve - and... fit's perfectly.

How does the Vishnu provide more torque even though its a smaller pipe? I was under the impression that turbo cars make more power and more torque with a free flowing exhaust, and that the more exhaust gas it could move, the better. Where as a N/A engine needs a little back pressure to balance the gases?
