Quick Vanguard catback thoughts
Hey, decided to go with a Vanguard Ti catback through the recent group buy. Thanks to Mike and Wicked Motor Sports for doing that. Installed it myself in the driveway (see the DIY)...took about 4-5 hrs including the head scratching to figure out the best way to do it.
So after having it on the car for about a week+, i gotta say it's quiet, but not as quiet as i was expecting. Maybe a better way to put it is that it's really quiet in some situations, but is louder in others. It's by no means a loud exhaust, but the biggest surprise is the volume increase at something like 1500-2000 rpm. I won't call it a drone, but it's kind of a resonance (while inside the car). So easing down your street in the morning isn't as quiet as one would hope. Once you hit 2000+ it actually quiets down and goes back to being very mild. At highway speeds, you wouldn't even know it's there alot of the time if you're just cruising. This all with very light/moderate acceleration, if you put your foot into it you'll get more volume across the board. Again, this is all experience from inside the car. Anyway, that's mostly all i wanted to report...it's very lightweight which is cool, tho i doubt you'd ever reap any real world benefit. The fit and finish is top notch, installation was simple. I went with the blue flamed tips, which were a bit larger in diameter than i was expecting (subjective whether this is good or bad). I can't tell a noticeable performance difference, but i wasn't really expecting to either. I've have catbacks on a turbocharged car that showed a 15-18hp wheel increase on a same day dyno and even then it's hard to truly say you can feel a significant difference. It may rev a bit more freely, but that's the most i can say. If i'm making a wish list, i would've preferred it be quiet across the low rpms and as loud as it wants to be at high rpms instead of the other way around. Here's a few pics |

Beautiful exhaust................how does it look when you are standing at ground level, does the muffler show a lot or does the rear diffusor cover it up. Can you post a pic on how it looks when you look at it from behind w/o the ramps? THanks, again, beautiful exhaust and diffusor.

A catback alone will only make the low end loud and usually die off when entering the high end. Pair it with an x-pipe and the high end will come alive. Looks awesome, and the tips look just right.

Very precise review of the Vanguard Exhaust... the fit and finish is definitely top notch! I also installed mine the same way using ramps
The sound of the exhaust was intoxicating during the Midatlantic ride this past weekend (see photo/video section). But I think the sound might be too loud for my wife. She's been complaining ever since it was installed. She really prefers the stock exhaust. I think I might end up selling this exhaust soon or eventually |

Yeah... it's annoying my wife so much that she prefers us using her honda element when we go out But I'm really enjoying the exhaust though. I was redlining the car during the skyline drive ride and it sounds so intoxicating... like an f1 car. Shareefo has a gintani exhaust and it sounded more like an american v8. BMWDEMON, i dont think i'll get rid of the exhaust any time soon so we'll definitely meet up in the next skyline drive meet/cruise. |

Most others have reported NO drone whatsoever. I now quite curious about this.

I'd say there's no drone. My definition of drone is like a pulsating almost pressure based sound phenomenon that happens with the engine at a constant rpm. This system is just louder at certain rpm ranges and is quieter at others under light load. I feel like it's gotten a bit louder across the board after putting on a few more hours of driving.

I think when most normal people talk about drone with aftermarket exhaust systems, they are talking about the annoyingly loud harmonic humm or deep booming sound all the way up to 3k-3500 RPM. I haven't heard the Vanguard in person and still on the fence but I don't spend too much time in between 1500-2000 rpm to think it would really matter to me too much. AA with their Noise Cancellation Chambers still drones I guess at 1000-2200 rpm. They call that excess noise "dragging". AA drone IMO, I think all aftermarket exhausts will amplify the stock sound at this rpm. |

Just FYI - I worked for years in acoustics with software for modeling automotive vibro-acoustics. I know what drone is... Back on topic.... I am still keen to get the key question put to rest. Some have reported drone with this syste yet others say there is none.

Without objective testing, getting any real answers to these questions is virtually impossible because every person has different ears, tastes and perspectives and because many aftermarket exhaust purchasers want to justify their $2k+ choice to themselves and to others.
