Boxer 6

I would like to replace the heat exchangers and muffler on my 1987 3.2 Carrera with a system that enhances performance and has a great sound (I am not concerned about the decibel levels). Does anyone have any opinions?

Cheers!

The GHL 911 Catalytic Converter Header Exhaust
System is without question the BEST exhaust system I have ever seen or heard.The fit is better than factory, the build quality is almost too beautiful to put on the car,the sound is nothing short of mesmerizing.This system also comes with cat by-pass pipes,which are easily swapped out depending on your needs.

B-6,

SSIs and a Dansk dual in-dual outlet exhaust, is exactly what I ran on my 3.2L. Worked great, sounded great (& loud). The nice thing about the Dansk muffler is that it is shaped just like OEM so it fits perfectly. The tail pipes sweep back, which is different from stock. I like the look, you can tell something's been done to the car.

The good news is I was able to keep the same set-up when I had the 3.6L put in my car (bigger engine-louder now).

Dansk also makes a dual in-single outlet sport muffler which sounds very nice, (& costs about $100 less) but ther is not much difference (a little) performance wise. With the dual outlet exhaust you WILL feel (& hear) the difference. The engine revs more freely and redline happens much faster. I don't know where you are in Jersey, but if you're not too far away from me and you want to take a ride (I'm in Rockland county, New York), let me know.

My exhaust (& engine) work was performed at DeMan Motorsport in Nyack-on-Hudson. Rick DeMan is an SSI distributor as well, so his prics (while not inexpensive) are very fair.

Good luck.

A cat bypass pipe and a Performance Products exhaust. Equivalent HP increase when compared to the SSIs and way cheaper too. If you need to replace your heat exchangers you can get used stock ones from Parts Heaven for $75 each.

While SSI's work on a 3.2L engine, they start to lose effectiveness due to the pipes being on the smallish side for a 3.2L eng. On a 3.6L engine, others have said that the SSI pipes <strong> are </strong> too small, effectively choking it. You may want to consider a set of 3.6L-specific headers if you want to optimize the power output.

Thanks for the opinions and advice. Anybody know anything about B&B systems i.e, performance, sound, etc.

Thanks

Bill G.,

You're going to have to take a ride in my car and then tell me that my SSIs are "choking" the engine. The engine revs freely right past 7000, so how can I tell if its being "choked"?

I will say this, if my current set up is "choking" the 3.6L, I can't imagine how the car would perform (or how much louder it would be)with headers. Add straight pipes (no muffler), like a real track/race car, and the car would not be permitted to run at Lime Rock.

For now, the car is still a street machine which I love to drive as often as possible. My office is only 5 miles or so from my home and I drive it nearly every day.

We'll have to hook-up at a driver's ed soon, so you can feel this engine for yourself.

P.S. Bill: I must add another oil cooler before the DE season, need to find an air dam so the extra cooler will fit.

Rich,
My 3.6 transplant has had both the ssi(1 3/8" ID primaries) and the B&B(1 5/8" ID primaries) on it. There is no comparison. The B&B really wakes the car up relative to the ssi and is really the only economical choice for header w/heat. The headers have no effect on noise, that is strictly the province of the muffler. I would not recommend B&B mufflers. I am using a Fabini. It is very aggressive, probably too much so for many people.
Here is a sound byte of the Fabiani;

Bill V,

You know I love your car, it's unique. But, I have to tell you the same thing I stated to Bill Gregory, my 3.6L is running great just like this.

How far away is Loudenville from the lower Hudson Valley? What track(s) are you near. I'm hoping to get to see your car beautiful targa in person this year.

Rich,
Mine ran good with ssi also, it just runs better with B&B. I ran with ssi for several years before switching over. Loudonville is just south of the Mohawk & north of Albany, I frequent Limerock, Pocono, and Watkins Glen

I had a B&B single in dual 3" outlet on my 85 3.2L and it sounded good from the outside, however I got alot of resonance on the inside from about 2500rpm and up. It was a little loud on the inside for long highway drives. Hope this helps.

The GHL setup w cats seems expensive and poorly designed to boot. The short primary pipes are great for really high rpm use(north of 7000) but do nothing or even detract from power for most of the rev range. I have ssi on my 86 I suspect that a euro pre muffler and good performance 1 in & 1 or 2 out muffler would have been as good on my 3.2

The ssi really worked well on a 75 2.7 I once had.

Boxer 6, I have a full B&B setup on my '87 3.2 Carrera and love it. I just switched up to a dual outlet instead of a single for more HP. If noise is not an issue, go with the dual out, otherwise stick with the single. I use my car primarily on the track so the Db's don't bother me. The dual outlet mufflers are also a bit more durable. I'll be getting a Dyno run done soon so I'll let you know what the results are.

I have the B&B header/muffler setup on my '86 911. The system is sounds and looks great in my opinion. I have the headers with an authority chip mapped for the headers, this really woke up the car!!! Don't much care for the GHL setup, looks more like two manifolds than headers.

Bill Verburg

Mark, looks good. I had B&B mufflers for years. Loved the sound but they kept cracking. The last iteration had a strut connecting the top of the can to the outlet arms forming a 45-45-90 triangular brace to prevent them from vibrating, B&B felt that that would cure the cracking problem. If you don't have them it might be good P.M. to weld some on.

To prevent similar issues with my current Fabiani set up I tack welded the inlet tubes and outlet tubes to the muffler can together where they cross each other.
