i just got my last part of my new ehaust . my newt setup is a RB downpipe, magnaflow muffler as presilencer and a 80mm corksport cat backand dam looks good, and like people said , it doesnt have much to baffle but with the magnaflow and the silencer should do the trick right? anyways looks great and i cant wait to put it on. heres a pics of my setup

 

It certaintly wont be quiet (sp?), but it shouldn't be too horribly loud.

 

cant be any louder that my broken pipes with no mufflers on

 

You might be suprised. For some reason when my exhaust was rusted to nother just before the rear wheel, it wasn't as loud as it was after a sport exhaust.

Can't remember if that was before or after I took out the cats....

 

my cats are gutted. i ran my car with just the downpipe one time and is verry loud, like you have to yell to talk, and right now the Y pipe broke just before the muflers and is almsot as loud as with just the downpipe aloneso i think it shouildnt be that bad.

 

i ran mine with just a 3'' downpipe and got pulled over i only ran my car this way beacuse i havent drove it in over a month and just got it back together but i will have almost the same exhaust as you i have a 3'' corksport downpipe to a 3'' borla xr 1 muffler to corksport 3'' catback i just need to find 3'' outside diameter exhaust flanges to weld onto my xr 1 muffler

 

I am running the EXACT same setup, but with a borla as a pre silencer; you will be fine, my NA with a RB header, RB pre silencer, and HKS dual 50mm catback was louder)
