M&K Single In/Out Feedback request

[Quasimoto]

It's nearly impossible to sift through years of layered exhaust threads, so apologies for contributing to the sprawl.

Considering an M&K system for my stock 3.2 with SW chip.

MKM33 Single In/Out Muffler with removeable OEM tip
Leaning toward:
MKM72 Sport Cat
Second choice:
MKM60 Bypass Pipe

I'd appreciate any comments from those that have this setup...particularly if there is a drone issue, and whether you would recommend Bypass vs Sport Cat.

Thanks!

Good morning,
I have had a M&K one in one out with a M&K Cat bypass on my 1982 SC for about a year. I first removed the Cat and installed the bypass with the factory muffler - car ran great but after a few months I decided to go with the M&K muffler.
In my opinion, the sound is outstanding and there is no drone, however it is a bit loud.
If you are concerned about it being too loud, I would recommend the M&K pre-muffler in place of the Cat bypass.
I am extremely happy with the quality of the M&K products.

Great info, thanks!

I had this set up on an 87 Carrera. M&K 1 in 1 out, cat bypass, and Steve Wong chip. I didn't find it to be overly loud or drone at all. It just sounded a lot better and more aggressive when the revs were up. It also made a noticeable improvement on acceleration. I think it's a great mod, go for it, you won't regret it.

I have a 1 in 1 out w/ a SW chip but w/ stock cat. Love the sound. No drone sounds great at WOT and under load but aside from initial startup won't wake my neighbors up when leaving early for cars & coffee.

I liked my M&K 1 in/1 out with cat bypass pipe on my 3.2. With a Wong chip I think it's the most cost effective "Stage 1" upgrade for these cars. Not too loud but not quiet either and importantly no drone.

Wonderful workmanship too.

Thanks again!

I've got th same setup as Dave. Nice cold startup sound. Almost wish it was louder. No drone. Doesn't piss of the neighbors. I like it. And it saved some weight over the stock exhaust.

Thanks again all... Think I’ll give them a call an get it rolling this week.

But first a really dumb question. Will the stock muffler drop out or does the rear valance need to be removed first?

The muffler will clear with a tug.
