I decided to go with Gibson dual outlet mufflers(2" inlet and outlets) and I also bought used muffler tips off a 987 to save myself some time.

Only thing I'm still kind of debating is what size piping I should use for the outlets of the muffler, whether to go bigger/smaller/same size.

These are separate views of the same evidence. Frequency alone does not establish a fix, and these counts must not be added together.

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.

POST 1 / ORIGINAL POSTEROriginal post

I really like the Tubi sound and kind of disappointed they don't make one for the 986. So sitting around bored, I came to the idea of maybe trying to replicate the exhaust without having to spend the money to try and retrofit the 987 Tubi system for the 986. Has anyone ever tried or heard of anyone trying to attempt this? Any ideas or input? here's a quick sketch I did based on the 987 tubi system

POST 2Original post

I love the idea and would love to hear how it sounds when finished.. What mufflers would you use??

POST 3 / ORIGINAL POSTEROriginal post

For now I'm thinking about using Gibson mufflers since they're not too expensive and they don't give that low throaty tone like most mufflers. Only thing I'm still kind of debating is what size piping I should use for the outlets of the muffler, whether to go bigger/smaller/same size. I'll definitely post pics and some clips as soon as I get everything in and get started.

POST 4Original post

I've been looking at tips and mufflers since I saw your original post! I would keep the pipes around the same size. Let me know when you get anywhere with this.. I've got a lift a welder to make installation and fabrication easier!!

POST 6 / ORIGINAL POSTEROriginal post

Just waiting on the mailman to bring me some presents. I decided to go with Gibson dual outlet mufflers(2" inlet and outlets) and I also bought used muffler tips off a 987 to save myself some time. Depending on the mufflers distance apart I can cut or extend the 987 tips. I'll post some pics up when I get it started.

2" is to big for a 2.5 Litre. I would use 1.75".

This is a source reference. Confirm exact model applicability in the original material.
