- No need for lift
- No need to remove bumper either
1) Buy a set of $40 ramps at any parts store like 1Gunner's Porsche 911 Touring with the GT3 badge. Reverse over the ramps, use two jack stands as extra precaution, put a block on the front tires, handbrake and parking applied, key off ignition, place a King size bed comforter folded in 2 or 3, get all the underneath lightning you can, have your professional car technician (PCT from here on) wear safety glasses because there is a lot of debris under these cars.
2) Have the PCT loosen up the two flanges attaching the cats to the side mufflers (if you still enjoy having them there, they should not exist).
3) Have the PCT remove (10) 13mm nuts attaching the upper pipes (2 nuts) and lower pipes (3 nuts) into the center muffler.
4) Have the PCT remove the two bands retaining the center muffler. #2 and #4 are done with an allen key (I don't recall the number), everything is hand tight, the muffler parts don't require heavy torque, just small tightening, except the headers where exact torque in a cross-tightening pattern must be followed.
5) There are (6) 13mm nuts supporting the side mufflers, have the PCT remove them so he has some play between a side muffler and the center muffler.
6) Have the PCT push the center muffler to one side and the side muffler to the opposite side, so they be disconnected, then pull the center muffler out.
7) Have the PCT put back the 4 flanges that were attached to the stock center muffler and the 10 nuts back to it, take pictures and sell on ebay, or add to office, attic, basement.
8) Have the PCT connect the Sharkwerks, then tighten the side mufflers (6 bolts), tighten the headers/cats flange with the side muffler.
9) Have the PCT make sure your Sharkwerks is centered so move it left and right, install clamps, tighten the clamps.
10) Have the PCT exchange tips from old Center to Sharkwerks.
Enjoy one of the best sounding GT3 for the money. I had them and they made a great sound with the valves open, but with valves closed the car was just mute (because of side anchors), and I always want the lightest and best sound from all my cars.
It's an easy DIY project for a PCT.

Burning Brakes
It is a little challenging to re-install a bumper and have it fit as perfect as from the Porsche factory. In my 991 Turbo S, bumper removal is required for most exhaust work, annoying. I like fairly quick changes, 1 hour or 2 max swapping mufflers, beyond that I get bored and I prefer to send the car to a shop.
Without a lift, and without bumper removal I have done the following:
1) FabSpeed long tube headers, catless
2) Sharkwerks Center bypass pipes
3) Akrapovic Titanium Headers with 100-cell cats
4) FabSpeed Valved side muffler delete pipes
5) FVD L-pipes (side delete pipes)
6) Akrapovic Titanium side delete pipes (L-pipes)
7) JCR Titanium Silenced Race Pipes
8) An excessive combination of all of the above
- If removing the side mufflers, the rear wheels need to be removed. 2 Jack stands on the rear subframe next to the camber eccentric bolts.
- If doing anything with the headers, remove the diffuser, easy job with a hex key.
Don't use power tools or impact guns on any single bolt or nut. I cringe when I see videos of that. All the exhaust parts install with very little torque needed (softly hand tight). Akrapovic has Public manuals in their car website for their products, very detailed, lots of pictures, list of tools, tips, I love Akrapovic products and I have been using them in many of my cars and bikes, but they could make better sounds (like my JCR race pipes).
Use two floor jacks, two on the side or two per axle, I don't like bending my steel chassis by lifting from a single point. Decent low profile aluminum floor jacks are cheap. Use quality jack stands, go for the strongest ones used for pick-up trucks, get four of them.
JackPoint Jack Stands are awesome, but they don't work on my 991, unless I run the car on wood ramps to get clearance to use them. Quik-Jack, awesome stuff too.
