What did you do to your 911 today?

[Arne2]

The enlarged ones have a muffler in there to keep the noise level about the same as with a cat. The straight pipes are louder.

Anyone know the reason behind the enlarged section of pipe after the twin pipes vs the smaller straight pipe version that is also out there? Is it performance, esthetics, EU coolness or some other reason not thought of?

Purdy polished vs...

Also offered by M&K

Possibly a design (larger tube) closer to the European cat bypass? Inquiring minds want to know... I've got a straight and even found an old OEM cat housing gutted and hollow in the box of schtuff I got from the PO.

It's what used to be called a resonator muffler on N American cars - It just replaces the CAT; a pre muffler vs a straight pipe aka ->CAT Bypass

(In Europe they have lower CO₂ regulations than we do, hense this is why their earlier 911's didn't require a CAT)

Yes there are 2 versions of this cat bypass, one is the MKM32 Pre-Muffler and the other is MKM60 Cat Bypass. The premuffler is a muffler and the cat bypass is a pipe, difference of course is sound level.

Dropped the engine for rebuid.

After repacking the CV's and new boots, I installed the passenger side axle. Now on to the drivers side.

Nothing special, truck bed fork locks from Yakima that I attached with self tapping screws. Good sized ones. They are adequate for regular bikes but when I haul the moped, I also use cinched tie downs on the handle bars. 75 lbs of weight is pushing it.

I tend to take corners less rapido with bikes on the rack. A bungie cord holds the rear wheel steady.

Cool, thanks man!

I extracted the last of the AC hoses, relays and wires.



Next to go is this wiring madness, which is some kind of keyless start/alarm abomination.

Finally got the new setup installed. Lots of open space under the bumper.
Next step is to get the new WBO2 gauge connected and installed.

Installed my awesome Rebel Racing motor mounts. Thanks Clint for all your help again.

Fabspeed airbox cover. I added the mesh to both ends. No performance expectations.

- 1 pound.

Installed Rennline fire extinguisher mount and extinguisher.

Ordered up a new set of seat-skins for my 1976 targa.

After removing the seats from the car I found this stuck to the sound deadening.

The car came from S.Cal, maybe it should have been a 1976 S and not a D!

Not the 1st kool "numbers" thing with this "new to me" 76.
When I got the title from the prior owner it had been issued on my birthdate.
And...the PDI date in the manual was my birth date in 1976 ( a young lad of 13)
