xede or procede? which one to get?

hey folks, looking to start ordering parts for my e93 so i can have them when it comes in. Just wondering, which one is better and how are they different? they are both by vishnu (shiv) but what are the diffferences in the piggybacks?

on a side note, it is possible to use just the rdsport exhaust (quad mufflers) with the vishnu cat-back?

We stopped using the XEDE nearly a year ago due to hardware limitations. The PROcede took it's place. It's considerably more robust in construction, has more inputs/outputs and is developed specifically for the 335. This is not opinion. This is fact. As a result, with v2, it makes considerably more power than we ever could make with the Xede. Since adopting the PROcede late last year, other companies (RD Sport, AA, etc,.) have picked up the Xede. I don't know what, if any, improvements they have made to the hardware or functionality. That is something that you would have to ask them directly.

This has been discussed an unbelievable amount of times. Please, please use the search function. However, since the thread is already here - procede and the various xede piggybacks are very similar in terms of install and performance as it stands today. People have their own opinions on which is better, but I don't think you will go wrong with any of the options.

Not sure about combining the rdsport with the vishnu catback though, don't think thats a good idea.

V1.47 is not lean by any means. All v1.x maps have nearly the same fuel map.
