Hi guys,

Decided to try a primary bypass on my 93 cab and wondering which one to order.

• FVD for $260: https://www.fvd.net/us-en/170111044/...y-muffler.html
• Fabspeed for $395: https://www.fabspeed.com/porsche-964...r-bypass-pipe/

Of course if you are somewhat local to the SF Bay Area and have one for sale, that's even better

Anything else? Any reason for the price difference?

Thanks!

they are all the same. go cheap. or buy used.

Good thoughts already provided. My car had one installed when I purchased it. I think it is a Fabspeed unit. I have had it off and on the car a couple of times while doing other work.

I would opt for a single piece unit over the two piece. I ended up replacing the hold down straps because the ones with mine were pretty junky. Used the factory straps from an early car and cut them to size.

Great, thanks for the replies.

I looked around and snatched a 50-mile Dansk for $200 (vs $300), it will arrive shortly

IMHO, that's the best sounding combination. Good move. I have spare secondary mufflers hanging around if you want one. Sometimes the secondary will crack due to the higher heat from this setup.

I've been riding with the secondary delete for a few years now and want to see how I like the primary only delete (and reinstall the secondary). I don't see any in the classified, but wanted to see if anyone has a used cup pipe in the 'need to sell eventually' pile they want to rid them selves of.

agree with this ^^^

i have done both... my take... j pipe is better for a street car as it sounds better at idle and mid range rpms and gives a little midrange torque boost... otoh rs pipe center delete take out more weight from under the *** and gives an hp boost but noticeable only when you really rev out the car... so better for track car or full out hot rod

Alright, the Dansk primary bypass has arrived and I had it installed yesterday. First off, I paid $200 and the seller was quite a stand up guy: he had lost a piece of hardware and as such, got me a completely new kit.



Unfortunately, I don't have the space and the tools to tackle the install myself and had to pay 2.5 hours to get it done. That was a bit of a surprise, I would have expected it to be a bit simpler but the fitting was not perfect out of the box and some nuts and bolts were difficult to remove. That makes it a $600 modification all-in.

I have not had time to drive it on a back road, I picked it up, drove it on the freeway and in the street. At low RPM it's somewhat subtle and that's exactly what I wanted. Not a major difference at regular freeway speed but you know it's there and it makes you want to go fast. Which I will do pretty soon.

Not a great video but it shows how mellow it is when you don't push it:


Oh, and that 12 lbs net weight loss? Looks like my butt dyno is not calibrated for 0.4% changes

Have you drilled the air box too? Very nice deep sound at WOT and 4,000+ RPM.
