PING D16Y1 with P29 pistons and std head gasket

yeap, 2.5inch on my d-series as well.... nothing wrong with it, though low end torque suffers a lil bit, top end feels much better

So do you agree with GSi_PSi? Or TheSaint? Because GSi_PSi's post includes a quote from a bloke stating that 3" would never make less power at any point in the power band than a smaller exhaust, therefore putting to rest the false theory that you need smaller exhaust on Honda engines to maintain back pressure for low-end power.


I have a 60mm mild steel exhaust for my EG sedan with a 5Zigen muffler, but I never put it on because I was of the idea that my low-end would suffer and since I use it mostly for daily/suburban driving this would not be ideal compared to say...a 2" setup.

My header is excellent. 4-2-1 ceramic coated 2" outlet, made by 'Flowtech' which is a subsidiary of Holley in the USA, who I believe have a lot of R&D + reputation (although bankrupt now lol).

So if I were to get either 2" or 60mm high-flow cat and install the 60mm cat-back + muffler on my D16Y1 I shouldn't see any low-end power loss at all?


That would be great, because I thought it would make the car drive like a bit of a pig...
