Does anyone has dyno chart for a stage 2 setup that only has a DP?
(stock catback)

According to Cobb's website, DP is the min. setup for stage 2. They mentioned there will be some performance lost, but I just wanted to know how much.

If anyone has a dyno chart with this setup, it will be great if you can post it!

Thanks a lot!

no dyno plot, but i have an 05 wrx w/ JUST an HKS dp and cobb Stg.2 OTS maps. the car is still VERY quick (it HAD a catback on it, which i took off due to noise problems (and 2 written warnings lol). no noticable difference power-wise.

I don't have any charts, but the estimate are around 5-10hp loss in top-end which doesn't really make much of a difference.

i'd bet it's more like 2-4whp with the stock, OTS map. protuned might be a different story.
