Quietest Angle Exit Exhaust?

What's the quietest angle exit exhaust? i guess u can say a catback, but yes.. i've been searching. Have not seen a topic for 06's and comparision of the quietest catback. Since I live in CA i'd like it somewhat quiet yet with the angle exit..

Also what do you guys think about the JIC Bullet 505 SS vs HKS Carbon Ti ? Noise wise that is. The thing I like about the HKS is that on the their site, they mention something about "HKS exhaust systems are engineered to comply with the 95dB noise limit law specified by the California Highway Patrol and the Society of Automotive Engineers" but I don't really think it's true since I hear the HKS is really loud..

-Thanks Tom

I guess your the one to ask. I have a lot boy at my Subaru dealership (I sell 'em) who wanted to know, "why are some exhaust angeled?" I have had performance cars for decades and raced for just as long ~ yet I still didn't have an answer, but for 'fashion'. Am I missing something?

I am is his tuner 'guru' and so far I have kept him out of Hondas and 20" wheels ~ but at times it has been VERY hard ;-)

Not sure if I'm correct, but my logic tells me that on some VERY low cars... like drifters, etc... or even street cars... while backing out or driving on angled surfaces or little bumps/valleys you could easily scratch the muffler... hence, its PROBABLY angled up for more ground clearance??? and perhaps tilted to a side for style, because well... angled up and straight would just make it look like your car has a chrome boner...

maybe the piping is too big, so it has to go under the axle rather than above it creating the angled look

* shrugs * thats the way it looks on my 240 anyways
