|
|
I put on the A1 Sidewinder on my 2276 the other day. It was wow, I mean really loud, especially from 2500 rpm onwards.
This is the A1 Sidewinder I put on.
Having said that, I also have another Berg exhaust laying around that I could use.
The Berg system
Is this a hideaway muffler or single QP? Is this quiet?
If this is also not quiet, should I be getting the dual QP like the one Glenn uses.
Thanks for your help. |

The Berg one is not a hideaway, it is a single quiet and will/should be quieter than the A1. I have that same muffler on my 1776 out of my 61. _________________ Pres. Rivercity VW Club www.rcvwclub.org

Either way, you will give up some performance the further you migrate from the A1. It is a better flowing exhaust from the choices. However, if you need quieter, the Berg is is probably the best compromise and i would suggest doing a dual merge muffler if the single isnt quiet enough.This is the performance compromise thay we all deal with on many levels. You should listen to my wasp stepped header and empi phatboy, its a whole nother decibel level. More performance, the more we all compromise someplace. _________________ 2276 IDA's 86C 11-1 DD !

Adding a straight pipe glass pack won't hurt performance I think. If there is maybe 3hp or less. _________________ 74 super beetle

It's the muffler not the header. You are getting the droan when cruising. You can try a different muffler. I spoke to someone running the same exhaust as you and had them remove the A-1 (I believe Magnaflow) muffler and replace it with one of the Dynomax VT mufflers and it helped a lot (has a flapper to cut down on the droan when cruising). http://www.dynomax.com/mufflers/dynomax-vt-mufflers
Also some have run the exhast into one muffler on the passenger side and then from there run a pipe under the tranny cradle and into another muffler on the driver side and out the back. This is supposed to really cut down the noise.
What size is that Berg set up-PM me about it. Thanks! |

How is the Dual QP compared to the stock exhaust in noise level? |

You see the pea shooter on your sidewinder? Just remove that and install the straight pipe glass pack like you install the peashooter . You will be amazed how quiet your engine on the freeway .

One muffler alone will not make the exhaust quiet, A1 or Berg. The Berg - may - be an expansion type muffler. Those will quiet it down a little more on cruise, but they will still bark at wot.
If you think that style of muffler (A1 with pea shooter look) is loud, the Berg will be a disappointment too for ya.
The solution with one muffler in extension to the sidewinder is not always good. On engines with cam durations in the 256-263 degrees @ 0,050 the exhaust length is apparently very wrong, because it hurts performance a lot. On these engines we do a "road racing" style muffler system with one muffler on each side of the engine, in line, and the piping crosses under the transmission. That works very well, and only kills 2-4 hp.
If you chose a black steel type dual QP like the Bugpack brand, if you can still get those, they are quieter than a sidewinder, but the ground clearance is annoyingly low. Dependant on the header of course, these start to limit the engine at around 150 hp.

If you pursue a different muffler than the one you now have for the Berg header, note the position of the triangular mounting flange on the muffler. Namely, the header has the flange oriented so that the bottom edge is parallel to the ground. This was Berg's design for a header on Ghias and Busses, so that the lower two pipes and the 4-into-1 collector came up slightly higher for better ground clearance. You needed to buy a matching muffler which also had its flange located the same way. By contrast, most generic headers have that flange with the right side vertical. That would mean that a generic muffler would not fit your Berg header unless you cut and rewelded either flange to match the other component.

Do you have a picture that you can post to show?
On the other hand, what do you think of the CSP Super Competition? Is that a quiet exhaust, in your opinion? |

Good point.
I now recall a couple of years ago I had this Berg Dual QP I bought from a fellow Samba member. I tried to fit that to this header and found that the orientation of the flange does not allow the Dual QP to go horizontal and I thought that may not be a Berg Dual QP, as it did not fit.
Do you know if Berg sells a Dual QP that would fit this header? |

I haven't had a stock engine/exhaust in 35 years.
You tell me.
