custom? or are u ordering something aftermarket?

 

the car already has apexi full 3in mandrel bend exhaust and apexi muffler

 

i use to have a built h22 turbo swap and ended up selling the swap and just gonna throw a stock h22 back in the car for a dd but didnt know if the exhause would hurt or help but graphs show itll help so thats great and thanks

 

is there any header for 5th gen with a 3in collector?

 

l wouldnt imagine it to help considering hondas run off back pressure

 

back pressure NO! no engine should have back pressure in exhaust. a good tune exhaust (header) will allow exhaust to flow in its normal waves. a good header will allow for scavaging of old exhaust gasses.

 

Stop posting incorrect information.

 

3" is proven gain for the 2.2L.

 

well this at least i will have something later to do to the exhaust, if i want to. i am 2.5in from collector all the way out. just finished and am looking for next power adder. maybe LSD or final drive gears.

 

now what would be a nice quiet muffler for a 3" exhaust?
I'm using the vibrant flat black now with a vibrant resonator and magnaflow cat.
Im thinking about getting an 3" OBX twin loop(I know...OBX) but seems to have good reviews and looks decent, cheap and quiet.

 

You are not going to quiet down a 3" exhaust. Just add a cut out to your current set up. Probably cheaper and you get the benefit of driving in a nice quiet car.
