Is there any data on the performance of the various catted downpipes? There seems to be very little info out there. Wagner Tuning is the only one that as far as I can tell has posted the flow rates comparing their catless, 200 cell, and 300 cell downpipes.

@Extreme Power House i noticed you have pretty much every downpipe in stock other than the akrapovic downpipe. What is your opinion on their relative quality/performance ignoring price completely?

As you know the Mods DB has some already, but not all DP's have perf data that I was able to find. Still searching/adding...

I did fantasize about getting all and putting them on the same dyno, along with couple of GoPro's with good mics and doing the same drive by, etc., but I am currently not willing to spend the resources to buy all and current weather sucks here! If any reseller company would be willing to work with me, I am totally up for it however it won't be before weather improves..~May

FtSpeed reviews many products on YouTube and in their product page. They have Remark & aFe Catback for Supra already, but no DP videos.
It'd be awesome if the tuning/reseller companies would do this comparison themselves.After all, it doesn't take too long to replace the DP if you have a lift and a helping hand.
They wouldn't be making any losses unless they have a product of their own, even so, in a capitalist world, this should push suppliers to come up with hopefully better or different products :)

There are very active people on the forum who have gone through a few downpipes already. If any actively modding person/company go through all using same equipment, same tune, etc. and report numbers that'd be great!
