If they fit on a Porsche, they're special pipes!

Bypass pipes is one of the few things that you can be cheap about.

There is no engineering going in bypass pipes, unlike mufflers, so not many reason to pay an extra! Only reason I see is fitment.

/!\ before buying any bypass pipes, ask the seller to give you the bolt spacing for the flange. Some might only fit if you have headers.

I added a set of secondary bypass pipes last year. TopSpeed is a vendor on the board and sold them for $160 Shipped. Not sure if the price has gone up but it is worth checking out.

Keep in mind that there is a lot more involved with installing a PSE than just swapping mufflers.

That's if you want the button and all the connections, right? The valves are normally open so you could install the muffler and leave it in the open condition full time.

The thread below explains it. On early Boxsters with the PSE option from the factory, there was no interior switch to control the valves. The exhaust was wired such that when the car went faster, the valves would automatically open. The early PSE had exterior shiny "sebring" style pipes that you could easily see from the rear. If you didn't get this option from the factory, many would just use metal cable wire to keep the valves open all the time, and this is fine as I'm not sure why anyone would want to silence the muffler, as even in the loud position, it wasn't all that loud. The 03+ PSEs sound better than the previous ones, as it had more growl.

On later PSEs from the factory (03 onwards), they got rid of the shiny exterior pipes, and so it looked like a standard exhaust from the outside except that the underside had valves and small pipes that couldn't be seen from behind the car. On these, there was a button on the upper console (shown in the thread below) that could open and close the valves at will. Honestly, the PSE is hard to come by now, and they don't drone, unlike most any other aftermarket exhaust (except the Dansk that I have as well as the home made PSEs done at muffler shops using the OEM muffler). If it were me, I'd keep the PSE and just get cat bypass pipes, but up to you to explore. You can definitely get a better sounding and crackling exhaust, but it will most likely come at the price of drone. Can you deal with that?

The default for the PSE is for the valves to be open, louder. If you wire the valve plungers down you will be closing the valves making it quieter. I have verified this with a cable camera. If you add a PSE to you Boxster just leave it as it is for a louder note. Again, IMHO, the PSE look great but are lacking in sound.

Thanks for posting that. I have always wondered about the switch.

This advice could've saved me concerns on a PSE months ago; I'll keep that in mind in my next opportunity for a PSE

Thanks!

If you want a PSE system, that requires the control system or a dash switch, wiring and vacuum lines. If you're only interested in the increase in sound provided by the bypass pipes, why spend close to or more than $1000?
Better to just buy the $100 bypass pipes in the link I provided and pay a welder or exhaust shop $50 to weld them on for you.

+1 on the bypass pipes. I used the Pedro method.

Awesome sound when you get on the throttle. However, I'm not crazy about the sound at low rpm. Not sure how to describe it...sounds a little too much like an old Rambler with a blown out muffler. I think the PSE solves that issue with the valving.

If I had to do it all over again, I would just send it off to Fister and have them do it.

Yes, Pedro hacked PSEs at idle sound like you have a broken muffler. The real PSEs don't do this for some reason. Also, I think the small pipes used to do the hack, if left visible from the rear, look like plumbing pipe not really fitting for a Porsche. Does sound much better at throttle though.

particlewave · 12-07-2016, 02:32 PM

Yes, the valves are normally open.

However, if you're negating functionality, it would be a lot more cost effective to just buy the $100 bypass pipes and pay your local muffler shop $50-$100 to weld them on. PSE's are not cheap.

rczap · 12-08-2016, 08:14 AM

Thanks guys, I didn't mean to highjack this thread but it seemed the appropriate place for it. I am gonna try to wire the valves open and see if that satisfys me. I dont think it will but who knows.

Bypass pipe diameter is a factor.

Need_for_speed · 12-09-2016, 08:56 AM

I used a larger pipe than Pedro, 1.5 inch -- much better appearance. Then I had my shop ceramic coat the whole catback assembly.

Fister does an additional modification to their retrofits which resolves the broken muffler sound issue at low RPMs. Not sure what they do...suspect they weld in a baffle at some point.
