Dyno - Burns Stainless Cans vs. Magnaflow 2-in-2 Out

If anybody has ever considered going to Burns Stainless cans, here are the side-by-side dyno results vs a Magnaflow. This is on a 3.4, 10:5.1, GE60, 46mm PMO's.

Both are bolted to the same 1 5/8" European George Racing Headers, and both run 2.5" tubing following a 2"<2.5" expander off the collector flange. The red line is the Magnaflow 2.5" 2-in-2 out. The blue line is two Burn Stainless 2.5"/4.5"/12" (photo)

The Burns cans only picked up a couple peak HP and ft lbs of torque at 6600 rpm, but at 4300 rpm it was 9 ft lbs Tq and 6 hp higher. The burns were a little higher across the entire curve.

Believe it or not...The Burns cans are quieter than the Magnaflow up to about 5000 rpm, maybe due to the crossover. At 5K, they start to sing a little loud, but it's a much cleaner sound...less "drummy". The Burns do have a drone around 2500-2700, but nothing like the M&K, and only slightly worse than the Magnaflow.

Overall opinion...A lot of money for a little HP, but the extra Tq in the mid range is really usable and the sound is awesome. Losing 15 lbs at the very tail end is nice too!
