FABSPEED SUPERCUP EXHAUST SYSTEM for 1976-1989 PORSCHE 911 CARRERA | eBay

The car is great and very sporty looking but doesn't have as much bark to what looks like it's bite on the stock setup. Would like to turn this thing up to 11.

Something like this

Would like to hear some suggestions on the best aftermarket setup you think is the best for having a more aggressive sound coming out the ass end. My lower left valence is cut out for current stock muffler but I'm open to cutting the other side for dual exhaust or modifing for center/GT3 style.

I'm aware I would not likely get to Rally Group 4 level carnage but need something between stock and neighbors calling the Police. Open to suggestions. Also, if you have something that you're getting rid of that might help would appreciate the look.

Thanks!

Believe it or not a flat turbo muffler can be fabbed very cheaply at your local indy muff shop. Avoid the Porsche tax. Tell them what you want and they usually will swap one on and let your test it.

I ended up just running a sport cat w/o a muffler on mine.

I used to have that on my 3.2 with cat. Sounds nice but I was looking for a more air cooled sound so I sold it and settled for a M&K 1 in 2 out GT3 style muffler with quiet riot baffles to bring back mid-range torque and quiet it a bit. IMHO, Dansk is the closest air cool sounding exhaust I have heard. I am willing to trade my M&K 1 in 2 out GT3 for a 1in 1 out Dansk Sport with 84mm tip.

bro I have a 951 and a magna flow exhaust system and it sounds great! I did hear a 911, with a crappy exhaust drive by while I was cruising and it sounded like an old v-8 powered dump truck with holes in the muffler. It sounded crappy!:eek: He passed me, and I could see the tips, they looked "new", be careful on your choice. You don't want your nice ride to sound cheap!;)

Interesting. I do have a local muffler shop that might do this. Can you give me an example of what a flat turbo muffler would look like?

Turns out I have a cat by-pass installed currently with what looks like a stock muffler although I'm sure could use an upgrade. Are the OBX cat by pass any good? $100 or so on eBay seems reasonable.

Also, found this but leery of anything custom made.

Also my first try at welding, lit my pants on fire, and boy do the welds look bad. Has held up well though.

Hear it here. That's with a minimum bullet style cat mandated by the rules, but OE heat exchanges otherwise.

Only negative would be I'd have to cut the rear valence for the right side and if I didn't like it I'm kinda stuck but I like the idea of dual exhaust.

Very cool. Guessing you're saving quite a bit of weight too. I have a guy that might be able to do the welding. Did you have angles measured out or just figured it out as you went?
