Dansk "Hotdog" Muffler for 2.5l Boxster

[RaisedOnPorsches]

Thanks for the responses. Topless, I agree a decrease in torque at the lower end would be a deal killer for me too. I assume this isn't the case with all aftermarket mufflers though, correct?

I've got some headers coming, I'll get those on first before I make the plunge into aftermarket exhausts.

Which headers and how are you going about a full system?

Currently, everything is stock, but I did just pick up a pair of new Schnell brand headers from another on this forum. I realize exhaust mods shouldn't be mixed and matched.

I'm debating between between 1) using the Schnell headers, having FD Fister-ize my stock muffler, and stock cats OR 2) waiting a while longer to save up the cash for a full Fabspeed exhaust system.

There isn't anything inherently wrong with mixing/matching exhaust pieces.

No? I suppose mixing and matching will mean more time at the dyno at least to make sure one isn't reducing the performance of the car.

AS long as the exhaust pieces are sized and flow what you want it doesn't make much difference. Restrictions is what make the differences.
Do the Schnell headers have cats, or are those down line?
Interested because I have a 2.5 also.

The Schnell headers are just headers. They're 2.5L engine exhaust specific. The 2.5L exhausts only have two catalytic converters located in parallel between the headers and the muffler.

All those cat-bypasses that you read about people doing are mostly relating to 2.7L and 3.2L Boxsters where they have four cats total, two per side. Folks are bypassing the secondary cats.

I'm sure there are still benefits for replacing the stock cats on a 2.5L setup with high flow aftermarket cats. Cats simply aren't cheap because of the rare metals that are involved in them.

That's about the full depth of my 2.5L exhaust knowledge at this point. Pelican parts has a decent write-up on exhaust mods.
