Anyone have DYNO comparison for downpipes and or FMIC?

Eat.Sleep.Race · 07-14-2014, 04:21 PM

Hello all, after browsing around the dyno sheets listed above i can't seem to find one person that posted A before and after with stock DP's then to 3 inch catless downpipes. What are the TRUE gains??

Id like to see.

Stock downpipes vs. 3 inch catless (no other mods)
Stock FMIC. vs. 7 inch FMIC. dyno

What is the True WHP/WTRQ gain from downpipes
and same goes for a FMIC? Are there any or just cooler temps?

Thanks and sorry for the silly post, i just installed the VRSF downpipes and was wondering what kind of power I added with them.

And what to expect when i install the VRSF front mount as well?

Without a tune i would say there is hardly any gain. Just about everyone has a baseline dyno on a dynojet of around 270 after tune+dp+intercooler its in the 360ish range. With Intake an e85 tune and hitting around 18 psi i would say you can get to low to mid 430whp. Hope all this helps.
