It likely to be very loud! Depends on if there i sany packaging in the main tube to quieten it

Similar to a cup pipe replacing the primary and a long g pipe replacing the secondary, but put together as a single unit

Looks home made or shop built. Note number of welds vs smooth bends. First comment is correct - replaces primary with smaller unit , an secondary is completely removed from system. Will be loud based on packing in primary. Can’t tell if Cat is on on/or used. For what is seen $200 is not bad price as you will pay more for cleaner, better set up

Cup “style” exhaust, but as Gus notes this appears to be a Midasized homestyle version. Similar to Borla exhaust.

It's just a small primary resonator with a fabbed Secondary delete, custom by the looks of it. What does the logo on the tip say?

That's kind of a funny exhaust for a street car. It's going to be brutal in the cabin...assuming that long section is not a muffler...or one that muffles...

But if you hate passengers...go ahead...cuz literally no one will want to be inside the car with you...lol. Anyway- without passengers, the car is much faster.

i can always have passengers wear ear muffs!!! He says it says Dynomax. Any thoughts? I don't think the primary is hollow but a dynomax exhaust from??? When and where I have no idea. I read a few things about them from posts in the past but nothing definitive.

I have never seen that one before. But in all likelihood you will just replace it if you're buying the car.

FWIW - all things being equal and without other changes- the oem exhaust performs best. So keep in mind that cup pipes or g pipes are, in effect, just a sound change.

I recently put my gpipe back on, and i have a headache when i arrive at work every morning. But i did it because i have an idea to work on interior noise over the winter- so i need so cabin noise in order to have something to tone down.

Dynomax is the muffler manufacturer they didn't make this exhaust, it's definitely custom made. Not worth $200 IMO - I would be especially scared of it without hearing it.

Ya I hear ya I'm gonna pass

I know I could go look. But Steve Weiner says cat bypass and g pipe/ Wong chip.
Anyone have suggestions as to brand without getting raped. Or anyone have something for sale?

I had fister 3's in my 993 and absolutely loved it. So that's the volume that I'm used to.

I had a Fabspeed cat bypass on my previous car, it bolted right on, with no fit issues. Highly recommended. Cat bypass, plus g pipe with get you close to 933 Fister lll sound levels, but not sound quality. I’ve spent a couple hundred miles behind various 993s with Fister 3s, insane noise and love the pops. No 964 sounds like that....
