hello everyone

looking for a little guidence before i take off my old exhaust. Bought this bursch one used and just want to ask a couple of questions before i get into wrenching. as per the photos it looks to me the bolts are part of the old exhaust and if that is so then presumably I need the bolts and nuts to put on the bursch??? Is there a recommended set of hardware that i need to purchase?

New exhaust gaskets, nuts and bolts and lock washers from local hardware store, and that ought to do it. That Cherry bomb muffler is gonna be loud. use penetrant and let it soak night before. Wear safety glasses, rust and debris everywhere.

Copper nuts are a good choice.

my apology, IIRC they had two versions, the one you have and another type, rectangular. the one I have is rectangular and to me is loud, but I am pretty sure the you have there will be louder because there won't be that much for the exhaust gas to be diverted through. record your current sound with your phone and then play it back after you got this one installed. spray PB Blaster or WD-40 on the rusty threads of the existing nuts and bolts. Hardest part of the job will be finagling the thing in place before you tighten up all of the bolts. I use Permatex gasket anti-seize, in case I want to change back the exhaust to something else.

Here is the quieter street version:

got it and thanks.
not too sure i will be into this new exhaust didn't want a louder one just a nice exhaust note and brusch was recommended to me a while ago. anyways i will rock this one out and if i don't like i then will sort it out later of put the old one back on..

IYHO what exhaust would you recommend for my 73, I am looking for something that sounds great not too loud, but then again if it is a little loud maybe that is a good thing, my car is not a DD and at some point i do want to build in a bit of performance...

I have a 2.0 liter and this is what I have on it now. but it is spendy. But it does give a nice deep throaty sound. In sequence of highest decibels, the Bursch you have is probably the loudest, then the rectangular bursch, then this Dansk gives the sound that is quieter and closest to OEM and give you the sound you seek. I'm speaking from experience from owning a 1.8 with a OEM exhaust 20 years ago and a 6 cylinder tail dragger.

Here are pics of the 2 types of Bursch mufflers. I have the one that looks like a regular muffler. Yours looks like the one that resembles the old "glass pack" muffler that guys used to put on their muscle cars. It's a straight through muffler with less back pressure and louder than the regular muffler.

I had one of those on my 1.7L and swapped it for a stock muffler because it was too loud.

Good I was not able to continue buying that exhaust. I immediately realize It is almost same glass pack I used and it is loud for a quiet neighborhood. I went to leisritz but the sound is like a vw bus for me. Thinking of a different exhaust, if i have enough funds i will be buying banana muffler. But don't get me wrong, that exhaust is still okay if you like louder sound.

That is the OEM one I had on my 1.8 Ljet 20 years ago. I am afraid it does have the bus sound, after all, it had a VW part number. But it will not be as loud as the straight Bursch.

The piping is what really counts. The 4-2-1 is the ticket. You can mount the muffler of your choise after the collector. Flowmaster, edelbrook, etc. you need to make sure the muffler clears the heat shield.

The Bursch 4->1 collector exhaust pipe set is a keeper. The glasspack/cherrybomb type muffler not so much. You'll want a decent muffler shop to weld together a new muffler solution to bolt to the Bursch, like a small Flowmaster or similar "muffler" to reduce the sound. That flange and 180 deg bend tubing on the glasspack may be something they can work with.
Good luck! (IMG:style_emoticons/default/beerchug.gif)
