Stoddard/NLA New Stainless Exhaust - Who has installed one?

[C J Murray]

Cheers,
Has anybody installed the new stainless Stoddard/NLA exhaust system? How did it fit? Any leaks? How does it sound? Do you have any pictures? Pictures of the position of the tailpipe termination? I ask that question since some of us have cars with no bumper guards. Inquiring minds want to know!

Brad, are the 2/4 head pipes extended into the mufflers to equalize all 4 head pipe lengths?

CJ,

I have only briefly seen and driven a 912 with this exhaust. Sounds good and I experienced no flat spots in normal driving. However, I do not know about the internal construction of the mufflers or how far the pipes might go into each muffler. That type of info might be proprietary to Magnaflow (Car Sound Exhaust, Inc), the manufacturer of the system.

The exit pipes may be angled down slightly to clear the bumper if guards are not installed.

Thank you Brad. I have the factory cutouts but not the guards. That is how I originally built the car also using the normal Dansk muffler and custom made s-pipes of greater diameter and extended a bit more to make up for no funnels/guards. I really don't like the low position of the sport muffler pipes. Well, the Dansk failed, I tried a stainless Dansk that failed quicker and now I have a GDP sport muffler type that fits great, sounds fine, but looks stupid because I have 2 unused cutouts.

Hi CJ:

For any exhaust you should use the Remflex gaskets that will compensate for most manufacturing defects to achieve a good seal.

Big engines run well with the stock muffler. Mine made a little more on the engine dyno with a 4 into 1 open race exhaust but that is not practical on the street. A friend with a mild 1720cc tested the new Stoddard system against the GDP sport muffler and the GDP performed best. I was using a Dansk stainless stock type which was fine but it shook itself apart, developed cracks and broke welds. The big engines do put more stress on the muffler. I am now using a GDP sport muffler which is beautifully made and reasonably priced. http://usstore.concept1.ca/Porsche-356- ... WIN-62911/

Has any one used

I have one of "Tiger's" stinger exhausts. It has a few thousand miles on it. So far so good. Fits well, no leaks. It is pretty loud though if you have an open car.

The Dansk on my 912 looks like a grenade went off inside it after 15k miles. Two holes and broken welds, explains all that backfiring. Anyone ever had any luck welding them back up?
