Tsudo catted downpiep and catback dyno numbers - Toyota GR86, 86, FR-S and Subaru BRZ Forum & Owners Community

PITTFRS · 08-05-2013, 09:17 PM

Hello,

I have been researching a lot of different parts including exhausts. I have had good experiences with tsudo in the past and was looking into them again. I just thought these dyno numbers I found seemed a little high? What do you guys think? It is on a dyno jet but they have the before and after. Here is the pic.

Does anyone else think this is too much of a gain for this setup?

Looks a little funny. I don't know much about dynos but aren't they usually in RPMs and not mph.. and the lack of torque curve is worriesome.

Has anyone ever found independent verification of these numbers?

After reviewing the DSport comparison where a cat-back gained 12 hp, I'm of the opinion that it sounds reasonable for a system that includes a high-flow cat to make 17.

With a tune maybe. With a header and tune definitely.

ive have the exhaust and a down pipe. it didnt feel any different, its not even straight thru or loud. maybe 2whp difference lol

I think that baseline dyno graph is a bit off. Too low power with way too much top end roll off.
