Exhaust recommendations......

[mede8er]

After fixing a buch of small probs on my 'new' 82 911SC I'm ready to go aftermarket with the exhaust...I've looked at B&B, GHL and SSI systems....I'd like to hear some first person experience with any of these systems...differenec between 2 in 2 out v. 1 in 2 out, etc.....BTW, after looking at the system closely last night for the first time I see the PO had a straight pipe installed where the cat used to be......

Little bump here........

After searching countless archives I've added Triad and M&K to the list......

Monty are very nice exhaust.

[Oh Haha]

Flowmaster is a nice alternative to the more expensive systems.
Usually less than 200.00 installed.

The Dansk 1 in 2 out OEM-style sport muffler is as beautiful to see as it is to hear... expensive though.

You can see it in this thread:
How Dansk Sport Muffler different? Dyno?

I think that most people will agree that the best you can do for your stock SC with respect to the exhaust is remove the stock heat exchangers, cat and 1 in 1 out stock muffler in favor of SSI's and a 2 in (1 or 2 out) muffler of your choice. That said, this isn't an inexpensive proposition. It is also illegal to do if you have emissions testing in your area. Check your local laws first. Figure up to $1,750 in parts for the SSI's and an appropriate muffler (if you choose one of the more expensive ones).

Probably the second best option is retaining your stock heat exchangers, remove the cat (again, illegal to do in some areas so make sure you can do it) in favor of a European spec or Dansk or Fabspeed pre-muffler and the sport type muffler of your choice. This option won't give quite as much power as the above nor will it look as trick from underneath, but is the most bang for the buck and will probably cost half as much to do.

The third option would be to leave the heat exchangers and cat alone and just change the rear muffler. This won't do too much for power, but will change the aesthetics and sound of the motor. There are many, many different muffler manufacturers, continue your research and see which one best fits your aspirations.

I am a fan of the Dansk sport systems with the 84mm tips, they look and fit like factory (at least mine did) and sound nice without being obtrusive.



Don't mind the headers, these are for a larger displacement motor where more flow is needed then what SSI's or the stock heat exchangers can provide. Also, using the headers means no heat and thus is not a viable option for many people.

Good luck with whatever you decide to do!

you gotta start with SSI or wait it out.

then it seems like the Dansk Sport and Monty are the best toned.. the rest are just loud imo.

single or double out is an ascetic & db personal call, not a hp call afaik.

I'd opt for the set up in the picture. You don't need heaters where you live so you can go with headers and have a lot more choices on the muffler although the one in the picture again looks great. Plus it's lighter than any replacement.

[mede8er]

Thank you all for your insightful opinions.....I think I'll do it right and go with the headers......

Bursch Headers are a bit cheeper than SSI if you can live without the heat.
I dont know if they are any good. I been locking at them for a while myself.

[Superman]

If you've done a Search, you probably already know I am crazy about my Triad. I get compliments all the time.

You need to decide what sound you are looking for loud or wisper?? Light weight or bulky and heavy (flowmaster is very heavy) Then you should talk to as many people as possible about the muffler you are interested in

If I go with the headers instead of the SSI Heat Exchangers will I still have to redo the oil lines?

Yep, most likely. I put headers on my old 2.7 and I had to replace the oil lines.

[mb911]

Mikes right you still have to back date oil lines

[earlyapex]

I've got SSI heat exchangers and a dual in, dual out Dansk muffler. The extra power is a plus and the sound is intoxicating.

[safe]

This is the hardline that goes around the engine just below the pully wheel, right?
Is that hard to change? Piece of cake compared to removing the heat exchagers probably...
Do you need to change the oilline that connects the hardline to the oil cooler too?

On an SC maybe (I don't know), but not on a 3.2L Carrera. Using George Narbel's headers on my motor did not require changing or rerouting ANY oil lines.

Since I am the one that initially showed you the headers from my motor, let me caution you now and tell you that I don't think that they are a good idea on your particular street motor. Heres why:

The header diameter is 1 5/8" which is too large for a 3.0L street motor. The SSI's are essentially headers which still allow for heat and are 1 1/2". This size is probably optimum up to 3.2L in displacement and certainly for a street engine.

If you go too large on the diameter, your low and mid range will suffer and your motor is not set-up to take advantage of the larger diameter (need different cams and induction) which is generally found at 7,000+ rpm.

If you have your heart set on headers, make sure you choose the proper diameter for your motor displacement and intended usage. George Narbel's headers sell for about $500 (with the extension pieces needed for a street muffler) but are NOT stainless steel. I would suggest having them ceramic coated as well for rust protection, which is what I did and you may be able to tell in the picture. Figure on another $100-$200 for this procedure. You are getting real close to SSI's in price now and will still have heat capability.

Ralph,

Funny you should mention the low range implications.... cheap throttle response at low end is exactly what I'm looking for at this time....this engine will only be in the car for 6 to 9 months while I finalize my plans and build my new engine....

Thanks,
Brodie

I use '74 heat exchangers and a Triad dual-out muffler on a stock '83 3.0. I have good torque from about 2500 up to 5500 RPM. I imagine it's a combination of the smaller intake runners and exhaust set up.
