With all the exhausts available now I wonder if those who have purchased one wouldn’t mind rating them in a few categories on a 1-10 scale (10 being the highest).

Rate Your Exhaust

Asking people to rate the volume of their exhaust on a scale of 1-10 is about as scientific as measuring with a micrometer, marking with chalk, and cutting with an axe. It's so subjective that you're not going to come up with any conclusive data.
What's loud to one person will certainly not be considered loud by another, and vice versa. Some people think that these cars are too loud inside stock. I say 7. |

^^ I would have liked to have posted on that one but haven't and probably won't just because it isn't a top priority of mine PLUS so many people have my exhaust someone is bound to do it for me haha.
I don't like my F.I. exhaust/BERK HFC combo..just sounds bad to me and is too loud and drones from 2-3k |

There is no better way to compare exhaust-systems than to hear them in person. |

And since one person will never be able to do this unless they spend thousands traveling the country, some decibel readings may be the most objective measure we get. Otherwise we'll be rating our exhaust loudness by ear with a scale from 1-10... |

In a nutshell the Stillen is a bit louder for my personal taste but others on several occasions have told me how they liked the way the car sounded. Two people followed me and stopped me just to say how much they liked the way it sounded. (have headers and high flow cats) If you keep a light accelerator pedal and the engine below 3000 rpm, the sound is very reasonable. Go over and it's louder than my particular tastes warrant.
My personal feeling is virtually all the aftermarket exhaust system will be very close performance wise. If you really think about it, they are 2.5 inch mandrel bent tubing, dual resonators and dual mufflers. Some eliminate the resonators but at what penalty? Loud doesn't necessarily mean more power and on two occasions we dyno tested my Corvette (stock and heavily modded) regarding open headers vs dual 3" exhaust system with resonators and mufflers showing absolutely no power difference. Think things like X-pipe vs H-pipe, 2.5 vs 3" exhaust, etc. are way overrated as header design is also. Bought a super expensive ($2K) set of stepped tapered headers with merge collectors that the mfgr said would produce 20 hp over conventional headers. Nope. The car dynoed the same as my cheap Hooker Super Comps bought from Summit. Called Larry Meaux who writes dyno simulation software and whose heads have 28 NHRA records. According to Larry, it's hit or miss on header design with some designs working a bit better on some engines and the same design on other engines not doing anything. In all his years of building race engines, he has never seen over a 1% hp difference in output from header design. Stillen quality.....sucks, but they are pretty cheap as compared to others. After the hassle of making them fit, I'd not buy them again. Last edited by Denny McLain; 09-28-2009 at 10:16 AM. |

Yeah I was really looking forward to seeing some results. Even though not totally scientific its much better than people's subjective opinion. I don't want to throw down cash on an exhaust when I have no idea how loud it is. Pipes that are too loud will be a deal killer for me no matter how good it sounds at low RPMs.
