Why is bursch muffler the cheapest...

[galileo]

Shopping around and saw the bursch is the least expensive of the most popular one used on this site. Is it the sound, fitment, finish, combination?
Can anyone chime in here.

BTW I have an 88 coupe, stock.

thanks, galileo

its is really LOUD

I see...I knew there was a logical explaination.

Roger Bursch was a Porsche mechanic and racer back in the 60's (and maybe before.. its as far back as i remember ) Anyway, he wanted to get more power from the 911 engines. He experimented with various combinations of the then popular glass pack mufflers. He knew that the mfi cars needed some back pressure in order to run correctly. He made two basic designs for carbed and mfi 911's. The sound of these systems is unique and higher pitched than sport muffler and similar other designs.

As such, they seem louder, but in reality are not. When compared to MK, Dansk sport, etc, the Bursch units are actually quieter ...... at first. Once the packing starts to wear out on those bullet mufflers, then its about even, maybe louder.

Since the company changed hands, many years ago, the new owner brought in different models for the 914, 911SC, etc. . A "quiet" version was introduced with the oval muffler design you mostly see today. As that one is not a glass pack type, its stays a lot quieter longer.

Whether you like the sound or not is subjective. Personally i think the single in/single out makes the 6 cylinder sound like a low rpm ski boat, especially when compared to the two inlet version. To me, hearing a two in/ one out version go by at full throttle, makes the car sound like its a bee whizzing by. But in a good way

The reason the systems are a lot less money, when compared to others, is that they are made from mild steel tubing and steel mufflers. The design also uses mandrel bent tubing. These factors help to produce the relatively inexpensive units.

As i stated above, Bursch sold to Horsepower Engineering. They sell the Bursch line exclusively thru dealers

Leo, that's what came with my car including cat bypass. Sounded good like a small V8 but after awhile the droning got to me.

I have a Bursch muffler (2 in 1 out) mated to HP engineering headers. The sound is awesome. It's not as quiet as stock but then that's not why I installed headers. For the money, it's hard to beat.

I have a Bursch MFI on my 2.7 MFI 1973. It has been on there for 10 years. The system really mates well with MFI. There is one larger glass pack muffler after the merge and 2 smaller ones in each pipe before the merge. I am sure there is no packing left in the system so it is a bit loud, but I like it that way.

I have thought of replacing it with another, but I like the sound, and I like the system. I have taken it off to add bungs for my Daytona-Sensors Wego IV AFR instrument. this was about 3 months ago and everything was very sound and in good shape.....no cracks, in good shape.

Horsepower engineering always made the systems for Roger Bursch. Doug Robinson is the owner of Horsepower and a Porsche guy as well as a Hot Rodder and Bonneville guy. Doug bought out Roger when he retired. The systems are made in Pasadena CA and are a great value for the money.......I know of nothing better for an MFI car.

Our host Pelican sells them.....TRE sells them, as well as many dealers.

Only maintenance I do is some hi-temp black paint once in a while.

I also have a Bursch exhaust one in/one out matched to a Bursch cat bypass. The muffler has been on for approx. three years and sounds and performs great. If cost is a factor, it is hard to beat.

and bursch spent a lot of dyno time developing their mufflers for the 911 line. Not many companies can say that. (Ok lots of companies can and do say say it - bursch has substance to their claim...)

I have a Bursch which I bought used. It has only one bullet glasspack muffler. Which type do I have?

Why is there a difference between MFI and Carbs? I've read about this before, but in my mind there should be no difference in back pressure requirements between MFI and carbs. Perhaps the different cams in those two types of motors?

I bought the Bursch because it is FIFTEEN pounds lighter than my Dansk sport.

They also use off-the-shelf mufflers, flowmaster, glasspack, instead of building their own muffler from scratch.

Still good sounding units.

They are not SS, so in year-round use in high humidity/salted roads their lifespan is shorter.

Since tuning an MFI is and can be a black art, I bet they made them so they were plug_and_play, so to speak in regards to stock motors. Pull old stock muffler off, install Bursch and drive away.
Now with all the info on the boards, one can pretty much tune an MFI car to run with any muffler/engine setup, THAT IS, if the car isn't a fraken motor. I have had so many damn mufflers (bursch triple as well) and the only muffler that really ran well was the stock muffler and the magnaflow muffler with glass packs (heavy and ugly as hell). The others ran but did not run very well, and yes I have a fraken motor. Now I run a dansk sport and it runs great, not to loud, not to quiet.

anyone have a sound clip of a bursch 1/1 out? Wil?

Low quality materials and low quality craftsmanship = cheap price.

I guess that is how I got 10 years out of mine and still going strong!! Great system as far as I am concerned.

[don gilbert]

they look like this after about 5000 miles. this one is for sale by the way, practically new. and cheap.

I have a 1 in 1 out in sitting in my garage that I had on my car for about 3 months. I then decided to go with SSI's and had to get the 2 in 1 out Dansk. I was disappointed with the sound of the Dansk compared to the Bursch. Side by side the Dansk looks like it is better quality build.

How well does a muffler need to be built for a car we use as a toy? I'm more interested in performance and sound than a stainless hunk that will out live me. I have one of those _&_ mufflers and the build quality is no better than the Bursch. Granted, it's stainless, but the fabrication and welding are not any better.
