Never thought I'd be posting this as my car was 100 % original. But on my rebuild I went 964 cam grind and now SSIs kinda fell in my lap
I'm going to try and get a used muffler. I know there is a popular one that is a two in one out.
The name slips my mind tho

Monty/Dansk/M&K?

I have a Dansk 2 in 1 out Sport muffler with SSI's and like the sound. Much lighter than stock and added a bit of hp.

Dansk !! that's the one I was thinking of , I see a lot of guys run it and it seems to be quite popular with the guys here so ill keep my eye out for a used one . I just hope its not too obnoxious. I already drive a classic Porsche I don't need to be " that guy"

theiceman

so is what I am looking for is basically a 65-73 Dansk muffler ? Will that mate directly to my SSI s ?

myflat6

Yes, I believe that is correct. I did this mod so many years ago I had to stop and think it thru. The two in muffler will match the SSI

Dansk is about the cheapest IIRC.

M&K may be the lightest

I am happy with my $600 monty, but they are now about $1,200.

A well-designed aftermarket muffler will add sound and not decrease hp. If you find one that really does increase hp (on an engine dyno, with a statistically valid test methodology), then put it on your wall and frame it.

If you want to read about an attempt to create the lightest possible muffler, then read the GS America thread, pinned in the 964 forum.

Light mufflers oftentimes make less power than OEM.

A GOOD sport muffler makes more power across the RPM range than stocks, but will make more noise. Our engine dyno cannot lie.

More noise doesn't equal more power.

This is also exactly what I have: love the sound! Not even close to "racetrack" loud or anything you'd consider obnoxious, but with a tad more bark and authority than stock, enough to remind you that you've got something special. And she revs freely to redline with that glorious note!!! Do it ...you'll love it

Steve- previously you posted that a Monty muffler was the best in you opinion. I am looking for an exhaust system & muffler for a 3.2 build I am planning.

Do any aftermarket mufflers provide performance improvements or do you need to add headers or SSI for HP gains?

r911

Tell him the size of your motor and the cams, induction, etc.


BTW, More noise does equal more placebo effect.

Ok so now it's a 2-1 dansk muffler. You guys sure do enjoy spending my money 😁

Monty's are indeed very good, the issue is price, especially without a US importer any longer. We use, recommend and sell the Dansk Sport mufflers for these applications.

Very little when connected to the stock cat and single-inlet muffler. SSI's or a good set of headers (no heat!) do make a noticeable improvement.

Steve Weiner-Rennsport Systems

I'm not interested in things that do not improve the car.

Thats what my customers expect, after all.

As Steve mentioned, the key really is the SSI's. When traded out the stock system to the SSI's with the Dansk Sport muffler, the difference was very noticeable. Getting weight off the backend was a bonus as well.
