Headers and Muffler?

I have a 72 911 T....I am looking for suggestions on headers (only summer car so no heat exchanger needed)and muffler? I would like something that sounds a little tougher than stock. But not much! Dont want a loud track type sound! And would like a muffler with dual outlets that exit Side Rear.....not middle rear. Any suggestions?

My understanding of the early exhaust system is that it is actually very, very good, and that beneath the heat exchangers are a very nice set of headers already. I think I'd just stick with what you have!

Also, if your car has mechanical fuel injection, you need to be very careful about changing the exhaust. A very good friend of mine had a '73 911S. He bought a very expensive (and nice!) stainless steel aftermarket muffler (Monty). Because of internal differences in the muffler, he could never get the car to run right. With the reduced flow muffler, he would have flat spots throughout the RPM range. He even tried, for experimental purposes, putting various plates on the exhaust tip to increase backpressure, but nothing would work! The Monty muffler, all $800 or so of it, became an expensive paperweight!

Brian is 100% correct and I am glad he said it. I saw the replies to you on the other bulletin board and they didn't address that issue. The mechanical injection needs specific types of exhausts. I can't remember the exact reasoning for that... maybe the pulse wave supercharging in the plastic stacks, but I have friends with horror stories about low or no back pressure exhaust systems. Be careful and ask more questions.

Brian, hope all is well with you and your car. I have been seeing a lot of posts by you lately.

Hi Marc. My "car stuff" involvement seems to ebb and flow, but has been pretty active the last 2 months.

Look for a feature in the January 2000 edition of European Car on my 74 914 2.0!

Brian is dead-on. I've got a 65 911 used on the track almost exclusively. Way back when, I installed some $450 RS headers to replace the stock heat exchangers - the only performance gain was in the weight reduction. The heat exchangers are headers, just with a bunch of extra metal, weighing a bunch more. They are also tuned correctly as Porsche wanted it for that specific engine. In other words, the exhaust headers on your car is the best, unless you are concerned about weight, and ease of removal since headers are lighter and really easy to take on and off. The stock heat exchangers are also easier to mate mufflers to, since they don't warp as much, and have well supported extension pipes. If I was not so lazy, I would reinstall my heat exchangers and remember what it was like to have a muffler that fit perfectly, not requiring monkeying around, since I change mufflers all the time depending on the track I run at.

My recommendation- don't replace the heat exchangers, but do change your muffler. You'll save a bunch of money! Hope this helps.
