CP-E 5" Catless Downpipe for N55
I recently had the opportunity to offer my N55 335i to be Custom Performance Engineering's test platform for their 5" Catless downpipe.
5" I said? Madness. Impossible. SO I went down to headquarters in Beltsville, MD and called their bluff. Lo and behold... here it was This is me with the catless DP in front of my face. After a day of dyno runs with baselines, JB4 Stage 2 Map 1, Map 2, WOT pulls..... We have a bunch of pictures, video, and data. Dyno's ________________________________________________ A 70MPH fan was used. 3 pulls were done for consistency for each test. Dyno #1: Stock Baseline vs Stock + DP Dyno #2: JB4 Stage 2 Map 1 12.5 PSI VS Same tune + DP Dyno #3: JB4 Stage 2 Map 2 14 PSI vs Stock tune Baseline Pictures ________________________________________________ MORE TO COME SOON! Many thanks to Mike @ VAC for the hookup! Last edited by turugara; 10-08-2011 at 01:47 PM.. |

I am not qualified to answer the 3.5" vs 4" vs 5" DP question so I'll let anyone with more knowledge handle it. I just know that there was a significant difference between baseline stock vs stock + 5" DP. Whether this difference is greater than what can be achieved with other brand's DP's of various sizes, idk. |

GoPro didn't capture it. In real life you hear the turbo spool like no other. Compared against a friend's AR 4" + Performance Exhaust N55, its much more noticeable with the CP-E 5" + Vishnu Catback combo. That's something that will require a better camera + mic setup to capture or your just going to have to take my word for it. Better yet, visit Philly!

JB4 Stage 2 Map 1 vs Map 2 doesn't show a significant difference. Is Map 2 really pushing out 14PSI?
