Dyno tested the SMSP style big tube header
I recently haven't been posting a lot lately but here,
Setup consist of:
1999 Civic EK hatch
Bottom end:
b20vtec 85mm 12.1:0 arias pistons
Eagle rods
Stock sleeves
Head:
Gsr head stock port
Ferrea valvetrain
Skunk2 pro2
Skunk2 pro series intake manifold
Skunk2 70mm TB
Golden Eagle cam gears
Hondata CPR coil pack
Hondata s300 v3 tuned by me
3" cold air intake
SMSP style big tube header
3" Stainless steel exhaust with Vibrant quite resonator and Magnaflow muffler
Last time the car made 220 whp 160 trq using jdm itr header "open" 214 whp 160 trq with Apex Noir 2 1/4" full catback exhaust. Got the smsp installed and went back to dyno and made some extra gains hp and trq. with full 3" exhaust bolted on. I"m happy with the results and the next part i'm going to be installing is my Skunk2 ultra street ported by 4 pistons. The 1/2" spacer is on the way so I"m gonna put that too and hopefully I'll see some more gains. Didn't get to dial in the cams at the dyno due to lack of time. Here's the vid at the dyno this past weekend. It was pretty humid getting into the afternoon time.

Nice numbers! What fuel are you using?
Curious to see how much it makes on the ultra street. I have one with the spacer and am considering getting the 4piston treatment done as well.

Nice numbers! Your exhaust sounds very civil for 3". Are you running a cat and what part# magnaflow are you using?

Re: Dyno tested the SMSP style big tube header
Just installed same header on b series ek.
Had to trim the factory fan shroud and factory fan in .5mm away from touching it.
Weird thing is the exhaust got more quite with this header and olm test pipe.
Just thought I'd add to the replica header info

I pulled the bracket that holds the condenser, fan shroud towards the front of the car by drilling 2 holes in the bracket. I have over half inch of clearance there.
