ok so i was thinking of just doing a 3" open down pipe, but i was wondering how loud it would be. or if i should just buy a 3" exhaust system. i would rather save some money by doing the open down pipe but i don't want it to be too loud.

by the way here is the setup:

F22B1 (stock internals)
Y8 tranny w/ lightweight flywheel
RPS clutch
T3/T4 .60/.48 turbo (internal waste gate)
Tredstone Cast-Iron manifold
Thunderbird intercooler
custom 3" downpipe
770cc injectors
Chrome tuned running 15psi

won't be too loud, but it would be too loud for me for dd duty. I have a full 3" for mine, but I went ahead and got a 3" cut out to dump it at the track.

umm i imagine a 2.2 liter would be louder than a 1.5 or 1.6 running an open dp... a month before i got my cat back, i cut my muffler off (back in highschool when it was cool to have a loud rice burner) and it was loud as fuck... no sneaking in late at night... and keep in mind that i still had the cat and the stock resonator... therefore it would have been louder without these... but then again, a turbo muffles exhaust significantly

thats all i got. this was when we first installed my buddies turbo on his gsr. to find that the seals in the turbo were fried, and that he should have listened to me and bought a new oil pan gasket.

it wasnt all that loud. definatly quieter than my car is now. but it sounded crazy in boost.

Open D/P will be a lot louder than with an exhaust. I personally, would much rather have a full exhaust, and decrease the risk of getting fucked with by police.

depends what your definition of loud is...

an open DP is quieter than a n/a civic with N1 style muffler and a test pipe by a long shot

i had my 3" open downpipe for about a day cause something came up and i didnt have time to install my exhaust that night. i didnt like it, i thought it sounded like shit. If it were just to head to the track or the dyno i would be fine with it, but its not for daily driving. It caused way to many people to look at me and my car for all the turbo spooling sounds and just how loud it was.

put the stock muffler back on... nothing like pulling up next to some idiot who loves proving that most civics are slow... and then seeing his face when you pull multiple car length on his ass through second gear... SLEEPER!!!
