Falcon SS versus Peco HDR

[Steve_S]

Falcon SS versus Peco HDR, same engine on same day. Sorry the recordings are bad, but it gives an idea of the difference. Both systems were mounted on a stock '67 BGT with stock manifold and downpipe.

What you will hear:
Startup
Idle
Rev to 2500 RPM
Rev to 3500 RPM
Rev to 4500 RPM
Hold at 2500 RPM
Hold at 3500 RPM
Hold at 4500 RPM
Rev to 5000+ RPM

The Falcon system suprisingly measures 4dB louder when revved, measured standing next to the car, than the Peco which uses a larger diameter pipe. Inside the car, the Peco is 2db louder than the Falcon under load, probably due to less high tones and more low tones, which penetrate the car's steel body more easily.

I think they both sound nice. Though, the Falcon has a little more of a 'crisp' sound to it.

 

[kennypinkerton]

Very informative... I kinda like the sound of the Falcon better... The Peco sounds very close to my stock exhaust.

 

[Steve_S]

It's funny, both here and on MGBE people all prefer the Falcon sound. But in real life everyone seems to prefer Peco. I think these crappy muffled recordings are too misleading. In real life, the Falcon sounds more stock and the Peco more racey and aggressive. The Falcon has more of a glass pack sound, kinda raspy.

My Peco definitely doesn't sound stock.

 

[ddrumman]

I personally thought that the SOUND of the Peco had more ball$.
I would prefer that on my B.

 

[jlaird]

The Peco does not have that death rattle sound when you take your foot off it.

 

[Nunyas]

turn down the bass on your PC speakers to get a more accurate reproduction of the sound of the exhausts... the Falcon doesn't have nearly as much low pitch resonance as you might hear in the recording... /ubbthreads/images/graemlins/smirk.gif

 

[kennypinkerton]

Makes sense now... I've a huge subwoofer on my system. It sounded really mellow and deep.

 

[DrEntropy]

I don't care much about the difference in the two sounds... given the choice, I'd go with stainless for a header every time. The Ansa system abaft is a good enough "tone ameliorator" in my book.

 

[kennypinkerton]

Stainless is nice... I went and bought a bunch of stainless hardware today to finish up some stuff on my boat. /ubbthreads/images/graemlins/thumbsup.gif It'll outlast the boat.

 

[Steve_S]

The recordings do not have headers. Stock system to the horizontal pipes.

Also be aware that stainless systems are typically veyr thin walls and are far more sensative to temperature variations. They are the most likely to develop cracks and leaks over time. I've become a real fan of aluminized steel, which is what all modern systems are being made of. I replaced all the steel Peco pipe with it on my GT the other day. It never rusts and stays a nice silver for life. /ubbthreads/images/graemlins/smile.gif

I put an aluminized Magnaflow on my Camaro about 6 years ago....After years of winter salt it still looks and sounds great. Nice system!

 

[MattP]

Does anybody have the Monza, or even better a sound file of it? I've been thinking about one for my B.

 

[Steve_S]

Imagine Peco, only more hollow and a lot louder.

 

[MattP]

Louder? That kinda rules it out. I come home from work at 3AM, and as one of the biggest whiners about the noise in the neighborhood, I best limit my contribution. Thanks for the input.

Steve,

I made it to that guy's shop this afternoon. It was another adventure trip. /ubbthreads/images/graemlins/rolleyes.gif I had him put the Falcon on my car. The catalytic converter and my asthmatic manifolds give it a COMPLETELY different sound from what it sounded like on your car. I mean you'd never know it was the same muffler just from the sound of it. The 75 and up exhaust manifold combined with a catalytic converter removes _all_ of the crispness that it had on your B GT. I'm left with a very mellow sound that's quite pleasing. At idle my 76 sounds a lot like the sound clip of your GT with the Peco resonator.

However, given the nature of the fiberglass hardtop on my car, I do have some resonant frequencies that aren't too pleasing around 3500 RPMs. It sounds great outside the car. I'm sure it'll sounds good while driving too once I get the hardtop off of the car. /ubbthreads/images/graemlins/smirk.gif

 

[Steve_S]

You shouldn't be running a hard top in So Cal in the Spring / Summer anyway!

I'm sure your later setup / smog gear is muffling the sound a bit before it ever gets to the muffler itself. Originally the Falcon had a resonator mid-car, which I removed when I got tired of smashing it on speed bumps. I would bet it would do more harm than good on your car anyway.

 

[Nunyas]

my previous muffler was mid mounted... it did ok 98% of the time... it was that other 2% that killed it. /ubbthreads/images/graemlins/rolleyes.gif

I've got a Monza on my 58 MGA, it's very loud....the kinda loud that makes your heart pound just standing near it.

Speaking of loud, my neighbors celebrated when I retired the Camaro from being commuter....To start it in the winter(at around 5:30 am) I'd have to push the throttle about half way, then crank it...resulting in ALOT of beautfitul throaty noise, and some black carbon....The noise would resonante off surrounding houses and wake up half the neighborhood. /ubbthreads/images/graemlins/cowboy.gif
