Ok this is what im thinkin i want to do and i want ask the experts. i wanna buy this muffler called twin loop and i wanna buy a new resinator but i dont know what kind of res i should have. i dont have to worry about emissions so that helps alot. piping is going to be 2 inch or 2 1/4 top from the cat back. with a aftermarket res going to be to open and float valves or no? and dose it matter what kind of res?

 

No just go on ebay and get a test pipe for your year civic and then prime it and paint it high temp flat black to keep it from rusting. I would do 2.25 or maybe even 2.5 if you ever plan to turbo.

I'm not sure of what res you should use, but 2 1/4 is fine.

Also, you are in PA? And you dont have to worry about emissions??? Hook it up with some info!

 

even 2 inch is plenty, don't go 2.5 it'll hurt your bottom end power and it won't sound that great it'll be kinda tinny sounding

 

Ya in PA so i have like no limits lol. ya i was thinking 2 inch is plenty cause i dont have the extra money to boost it yet. As long as 2 isnt to much. i just want to make a little more power and have a little bit of sound. All the people around here run neons, cavs, and sunfires. i dont have a problem beating them i just want them to think twice about messin with a honda

 

not neccicerily all of pa dont need emissions.. My house is directly on the border.. the county lines run right thru our property. Westmoreland needs emissions and Fayette dosent.. so you know where i claim registration at right?

 

LOL same as me thanks for the input
