going through the 3.0 rebuild and need to finish with the replacement of the stock exhaust and muffler which will provide the best sound and hp increase for a 2 in 1 out system

I put Dansk on mine. I like it.

Ugly lump. Probably worthless.

Is the Dansk muffler inlet/outlet the same diameter as stock? If it is larger does it mover the sweet spot higher in the rev range?

A Dansk will give you good mid range.....going for sound alone and free'er flow/big pipes ruins the mid range on a stock lump.

What's this? Another opportunity to post the sound of my exhaust? Well okay if you insist.


SSI with 2-in-2-out Dansk. Haven't dyno'd it to compare to stock, but probably lost a bit of mid-range torque (though with the way it sounds I don't really care). Going from the stock headers to SSI is going to be an improvement across the board, though, from what I understand, so you won't really be losing any torque.

If I copy your SSI and Dansk with 1 out set up on 1980SC stock engine, would I get similar sound?
Any idea how performance is affected?
Thanks for any comments.

Less volume with the 2-in-1-out, though a similar tone. Here's an SC with SSI with an M&K 1 out. Not sure on the performance difference.

Dave, that sounds amazing.

Yes, your 2 out sounds better to my ears, love the agressive race car sound....but even this 1 out example is way better than my stock setup.
At this time I dont want to alter the rear valance of my Weissach with a 2nd cutout. My 84 has 2 cutouts from previous owner and its impossible to find a stock one for reasonable money to make it stock again.
Id even consider running a new set up and removing the rear valance.
Thanks again for sharing the 1 out information and video.
Very helpful and thanks again for your comments.

Dave Inc.

I just removed the stock valance for the center outlets and put it into storage. I kind of like how I can see the muffler from the rear now without the valance, but figure I need to pick up a fiberglass one and get it cut one of these days.

tgil

Thanks for your comments, and I am on the same page with running minus the valance, to see the exhaust similar to the 356s.

m&k 2 in 1 sounds great.

almost ready for the SSi's and the 2 in 1 out Dansk polished stainless....ulgy lump indeed
