Bursch Header / Muffler, Bursch Header / Muffler revision to mitigate rasp Options

[forrestkhaag]

I am interested in a solution for creating a decent muffler by using my recently purchased Bursch Header/Muffler setup to best feature the new and improved sounds that will emanate from the rear of my (newly built) 2.2L 914.

Recently, I purchased a new-in-box Bursch system that was supposed to be Street Quiet.... - but it isn't close to "street quiet" even on my 1.7 engine as it is presently in the car. My approach is lop off the muffler-can on the Bursch product, then splice in a Magnaflow or other real live tuned muffler-element, then add the outlet pipe to match my valance contours. Size matters. The add-on needs to clear the underside heat shield as I do not want to cook my lovely wife's unmentionables while touring the California Coast.....

: Sidebar: My pal on 914W Larmo has the Bursch system on his 1.7 and it has a totally different and very decent sound as installed / right out of the box / - and it was purchased in Pasadena from the same supplier / maybe my system did not have the "street-Quiet" can welded to it but his is clearly different and decently throaty but not raspy in sound - both on 1.7 stock FI engines..... not sure what gives..

Do any out there have a recommendation for a replacment insert-piece (Magnaflow, or other) to gain a decent amount of muffling while featuring a throaty tune that will respect the neighborhood while mildly inflating the ego of the driver (me) while at the same time, eliminate the sneers, recoil, and window-slams of the neighbors............


Thanks for your assistance

I found this for you Forrest:

Follow up post regarding replacing my Bursch muffler with a Magnaflow using the Bursch collector and tip.

I used a Magnaflow 11124 from Summit Racing for $87 - I found it even cheaper….



The Magnaflow size was very close to the Bursch, only issue was the tip now protrudes an inch or so less which is fine - always thought the Bursch tip was too long.

Also I'm running a 2056 with dual Webers.

Good search. As a follow up, take a look at post 16 on this thread:

I had included a couple of sound clips in that post.

My first Bursch, on the car when I bought it, was raspy but attributed it to it's internally rusty state. The new Bursch was also raspy, thus the Magnaflow swap - a slight bit of rasp but not very noticeable. The overall sound is deeper and more throaty.
