k20 2.5" or 3" exhaust!!

[Nepolian]

hey mate, did you have to retune your car after you got the exhauste? cause im in the same boat as you, i have i/h/e/kpro and was wantin to go 3'' but was worried bout retune...

Not too worried atm as I'm sure just the exhaust wont change mixures that much. I am doing some intake mods and will consider re-tune after that as it costs a small fortune to have it done right

wat intake mods are you talkin about? wat type of intake r u running now?

from what i heard. the K20 Engines dont like restricted exhaust flow. soo yeh if this helps in any way. thats why no k20 would get a twin loop =)

So would 2.5inch straigh thru be beneficial with bolt on mods? I kinda want it to be like a bc spec 2. I miss that high pitch note =)

as long as you don't go below 60mm that will be beneficial.
straight thru zorst sounds awesome at WOT, sounds like formula 1 except the speed

I kinda feel kinda embarrassed actually, coz it's freakin loud but the car is still quite slow. If I got a fully build motor maybe I won't LOL
