Coverage and how to read this overview

Counts describe captured discussions, not unique people or a diagnosis. Author identities are not reliably stored. Exact duplicate evidence is counted once across matching discussions; one discussion counts at most once per action/state. Multiple repairs reported together remain a combination. Suggestions and failed attempts do not establish a fix. Matches cover whole discussions and can include related faults, model variants and incomplete threads.

15 eligible posts · 0 unverified posts · 1 discussions match the subject in their title or opening post.

0 evidence records excluded for query context · 0 excluded by outcome qualification · 0 adjusted by outcome qualification.

0 acknowledgements have no verified action link; they do not establish a repair result.

POST 1 / ORIGINAL POSTEROriginal post

So I found these mufflers for sale at a REALLY good price . Seller knew nothing about them . They have no ID plate or any marking . I cleaned them up and they look/feel solid . Welds are very well done and the mounting brackets are thick . They are going on my car regardless of what brand they might be but there are some smart folks on here . So any guesses on what these are ?

POST 2Original post

My guess is that they are the "loud brand ".... Slap them on and see how they sound......

POST 3 / ORIGINAL POSTEROriginal post

Ptech3 actually I am hoping they are on the milder side . My 3.8 with aftermarket headers and catless x-pipe with Fister mufflers is quite aggressive . Yeah I am getting older . So I am hoping " sporty " sound with less bark than the Fisters . Plus a little weight off the back . We shall see .

I don't think so . I believe Tubi stamps their name on the muffler end plate . But I could be wrong .

POST 7Original post

I uploaded the picture to Grok and it narrowed down a few items. Could be DesignTek Sports Supremacy

Appreciate the leg work , you could be right . My lift is currently occupied with a suspension refresh of my 986S. As soon as that's done the 996 will go on the lift and we'll get these mystery mufflers installed .

POST 9Original post

Those look like the one's sold on ebay/chinese brand 10-12 years ago. I remember those brackets. I believe maxspeed were selling those also.

POST 11 / ORIGINAL POSTEROriginal post

Yesterday I removed the Fister modified mufflers and installed the mystery mufflers 😁 . Today I fired her up and I liked what I heard . A slight rumble at idle but much quieter than the Fisters . Took her for a drive and when warmed up I let her rip . The 5k to 7k full throttle sound is very refined . It's definitely a flat six sound . Just more subdued . I am VERY happy with the results . Also saving 20 lbs off the backside is a bonus . I took a chance on some used mufflers and came out a winner . Sorry no sound clips .

Glad they worked out, the weight saving is always worth it. Maybe do an X-Pipe and 200cel cats next

POST 13 / ORIGINAL POSTEROriginal post

Quotes source post: 20185643

When the engine was built to a 3.8 I added aftermarket headers and a catless x-pipe . That setup made the Fister modded mufflers too loud for me . The mystery mufflers have toned down the exhaust note but still sound like performance . I am 100 % happy with what I have now .
