Hi all, new to the forums! I was looking into a new manifold 421 was wondering what to do with the cat? can it go under the car or would i need one specifically to go under the car? Want to avoid a decat if possible. Sorry if its silly question, new to the whole fixing up cars let alone hondas :biggrin: :sign4:
Had a quick look just cant find them, all i seem to get is decat pipes. Is there an advantage to decat or will you just need to put one on for an mot? Im in the uk so dont know if its hardened to get that stuff here? Thanks for you help sorry if i sound dumb!
I have a d16y8 header that slo-eg8 shipped to me, hooked to factory style dx midpipe and muffler.
You can definitely just go header to stock exhaust.
Beware that the ebay headers do NOT like sealing properly to stock style midpipes. I suggest going to a partsstore and matching the ebay donut gasket with something a bit thicker and crushable.
Also, use spring bolts like normal exhaust. straight bolt and nut is a leak waiting to happen under the car.
Thank you helps a lot! Hopefully getting a japspeed one will look into the gasket already trying to get one for my inlet manifold to
