 |
|
| trying to see if there is anyway to quiet down the EMPI header and muffler system on the 1776 dual carb system on my '67 split..anybody with any good suggestions as the exhaust seems loud to me...going to a single carb would be expensive and I would loose a lot of power..or so I have been told..but it would buy me a traditional muffer system..Thanks for any help |

Run a stock exhaust or a Vintage Speed exhaust ($$). The carbs are not making it loud, its the cheap exhaust.

I was not impressed with stock exhaust on my 1776 with single or dual carbs. I was also not impressed with single carb on 1776. I'd keep your setup and try to mitigate noise with some sound deadening in the interior.
Also check for exhaust leaks...

Not sure what year you're working with... but vintage speed has fitment issues with '58 & earlier... maybe '59 too. Muffler hits up against the rear apron.
I was going to buy one before I corresponded with them & they said people have needed to make 'modifications' to make it fit on those years (& earlier).
From what I remember... the modifications looked like they needed to dent in the muffler.

Any muffler designed to fit a stock 1600 based engine will fit a 1776. All that number refers to is internal displacement. They have nothing to do with the style of the exhaust.

Vintage Speed has a muffler that will work with heater boxes. You only have to get rid of boxes on bigger motors which need more flow but a 1776 should be fine with heater boxes. |

| So I found the vintage speed muffler that works with heater boxes..any one know if I need the adaptor flanges that they sell seperate?? I understand just enough to be dangerous...I was told you can't put on a stock German muffler on this because of the dual carb set up otherwise I hope this $$$ Vintage speed fits...1967 bus...thanks for the imput.. |

They come set up to work with stock heater boxes/flared j-tubes to be hooked up with the stock donut clamps. If you have flanges on your heater boxes/j-tubes, then you need the flange adapters. They do not come with preheat hook ups, but those are available for extra $ |

The results are in. There is no point is posting all the numbers as they are all pretty close.. 57 hp at 2500 120 ft lbs torque with all 3 systems, with the max hp at 4500 between 92.5 and 94.5hp with Vintage speed making the lesser of the 3 with average of 110 ft lbs of torque. I weird thing was the Vintage Speed made 6 to 7.5 more hp at 3000 rpme then the stock and A1 making the lesser of the 3
Stock heater boxes with Thunderbird header and fat boy muffler won for low end . A1 tied the stock for mid and high end and Vintage speed was close at low end but fell off 4000 rpms up...
Both the stock and the A1 could be made to work even better with a different muffler. Both the mufflers used flow to much for stock heads and the extra back pressure would help gain power (didn't have time to due these test) In talking to Tiger from A1 head could modify the 1 1/2 sidewinder collector and put a more restrictive muffler for better gains.
The Vintage speed is what it is.
So which to use? Whatever one you like the best. If you want heat either the Thunderbird or A1 with heater boxes. If you want the look either Vintage Speed or A1. With a stock valved engine it really won't make that much difference in systems, but still an improvement over a stock muffler. It seems it could get down to dollars and cents. A thunderbird with muffler around 140 or so dollars, a Vintage Speed or A1 close to 500 dollars.

I really dont see spending the $ on the VS exhaust especially with no real performance gain (non equal length) compared to a standard header.
I had the empi single quiet pack and that thing was loud and annoying.
I personally run an EMPI premium flanged 1 3/8 header with an S&S turbo tuck muffler. Excellent flow and fairly quiet and good ground clearance.
The empi version is pretty quiet too.
The bugpack versions exit pipe hangs too low so most just cut the down pipe off and run it straight back.
The good thing is when the muffler wears out you can get a better quality larger one that will be even quieter.

Ground clearance, looks, sound, wide range of options, and you won't have to buy a new one every 2 yrs. |

The last empi header lasted 17 years. The S&S muffler is going on 22 years. Given I dont drive in the snow/salt but putting some quality exhaust paint when new goes a long way.
I noticed that performance was not one of the criteria you listed. Most tuners stay away from the VS due to its strange torque/hp curves.
The VS exhaust Ive heard were pretty loud and that is something the OP is trying to avoid.
