Installed a divided turbo elbow (generic XS power), 3" test pipe, and custom 3" exhaust on my SR'd S13 (already had a 3" DP). I bought the exhaust used from a local guy; it's 3" piping up front, welded to an HKS Hi-Power rear section. It does have a resonator welded into it.
And it is fucking loud as hell. At idle it sounds great, really deep rumble, but under acceleration...Jesus. Just rolling around town and staying out of boost, it's just obnoxious. Really drones at lower RPMS, between 1.5K and 3K. Oddly enough though, at higher RPMS and WOT it's not too loud, sounds really good.
Is there any reason not to think that cuttting out a section of the exhaust and welding in another 3" muffler would help quiet it down a good bit? I like the way it sounds, it just needs to be about 20 decibels quieter for around-town driving
