1.    Exhaust

1.1    Healey 6-cylinders

From: Jim "AH102" <bluechipracing_at_snet.net>
 "Here's my .02....    I've had original, I've  had Stainless, and I've had Monza.  Nothing comes close to the sound of the original mild steel system.  Actually, I'm using SS front pipes, SS tailpipes, and a mild steel burgess muffler on my BN7.    Good for twelve years and 25,000 miles so far, and still sounds great.  The SS muffler had a softer sound and to make matters worse, it began to rattle inside after two years.

The Monza system on my BN6 (BJ7 engine with Ruddspeed tricarbs) sounds ok but it doesn't fart going through the gears like the original does.

 

1.2    Curing the leaks of the Healey SS exhaust

Curing the leaks of the Healey SS exhaustat the front of the muffler:

…I just completed exactly the same repair on my exhaust using "Ultra Copper" High Temp RTV Gasket by Permatex. On 2-stroke go-karts; they use the Ultra Copper on their exhausts and say it is great stuff that lasts.

 

1) I'll assume that you have the muffler pipes that have the "split" in them. Apply a good-sized bead (1/8" to 1/4") of sealant around the inside of the muffler pipes BEHIND (i.e. further into the muffler) the pipe splits;don't apply any sealant to the header pipes. This way, no sealant (or very little) should squeeze out from the splits; any that does can be wiped off easily. Reconnect the pipes so that the end of the header pipes go somewhat further into the muffler than the point at which the sealant bead starts; this way, there will be a good seal between the pipes.

2) Once the pipes are reconnected in the position that you want, work some more sealant into the muffler pipe splits; I didn't do this and there is just a slight leak at this point, which I have to fix.

3) Re-clamp the muffler pipes, but don't over-tighten; this will deform the pipes and make for a poorer seal. My clamp position is directly over the splits, so none of the sealant should be visible. Re-attach the resonator bracket and tighten all the other hardware. Leave the car for at least 12 hours to let the sealant cure.

 

1.3    MONZA (too loud?)

From: "David Dressel" < daviddressel_at_hotmail.com >

Being kind of an old fart, I was a little worried about putting the Monza system on the TR3 I just restored. Just doesn't seem dignified to make too much noise at an age where you can't back it up. Anyway, took a chance and bought the system. I love it. Not really noisy, just "throaty". Definitely a good choice for me.

Have a Monza on my TR3 - yes, it is probably a little louder than stock, but I haven't really compared. I do like the throaty sound though - but it does hang real low and I do hit it if not REAL careful on speed bumps, etc

1.3.1    When it is Too loud

From: HDRIDER570_at_aol.com

J. C. Whitney sells Pipe Baffles for motorcycles ( part # 01AW3524N ). I installed them in the inlet pipe of the mufflers with the bell ends facing the engine.  They came with bolts to hold them in place but I decided to plug weld them.

I have driven the car about 70 miles now and it is much quieter with no noticeable loss of power.  It is still throaty. The baffles cost $3.69 each so it was a pretty inexpensive and took about 30 minutes to install.

Subject: RE:Monza Exhaust? In a word, LOUD

One of the guys on the list suggested getting tail pipe inserts from www.jcwhitney.com. I ordered them and installed them on my monza and it made a terrific difference. I can actually hear the stereo now and the car still sounds sexy. As for fit, I had meineke install it for me. They did a fantastic job and yes, it does take some drilling / welding to make it fit perfect.
