Will a “S” muffler fit on a non S 986

S muffler up to 2002 will have the welded on tips. 2003 and after will have the removable tips. You want the welded tips. The fister mod runs tubes into the tips. I have a 98 base with a 2000 S muffler. It works fine. All the pipes are the same size. You might want to buy a used updated muffler bracket if your car doesn't already have one. I'm not sure of the year of your car. I'd imagine 2000 and later have the newer bracket. I was able to mount the muffler using the old and new bracket. I prefer the new bracket.

I have a 2001 and if fister welds the pipes inside would that defeat the argument about different size pipes with the s vs non s

I have a 98 base. The entering pipe sizes on the S muffler are the same size. I'm not sure where the other guys commenting on this thread are getting that they have different size pipes. I felt no loss of power when I put on the S muffler either.

I actually did the internal exhaust mod on my S muffler. Still no loss of power and way more sound. The internal mod is basically the same mod as the fister only there are no external pipes. My friend had the fister mod done. Our exhausts sound about the same. His cost was whatever fister charges plus shipping back and fourth from NY to Cal. My cost was the price of some drill bits. I was able to weld mine back together at work. If you can't do that i'd think a muffler shop could do it for under $100.

The mod is in the link above.

The entering pipes on the S muffler with removable tips may be larger. I am only talking about the S muffler with the welded on tips. The welded tips muffler will bolt right up with no problem, same size entering pipes, no loss of back pressure, but with better looking twin exhaust tips.

Fister said kinda the same thing that it should be interchangeable. I ended up actually just buying a muffler from a dismantler that’s an S muffler and it’s right down the street from them. I only have to pay shipping one way. If it’s too loud I’ll just sell it since I’ll have my stock muffler too

It won't be too loud. It will sound great. If you decide you don't like it you should have no problem selling it.

I was planning on adjusting the output with the cat bypass pipes, If I want it alittle quieter I’ll have the stock cats on and deal with the drone but I imagine I’ll use the pipes. Would you suggest circuit werks? They are 160$ just not instock currently
