Thanks, looking at it last night, it is the right hand(passenger side) one that is missing the insulation. took me quite awhile to pick a flavor, fudge did it, but with no sugar, I have to watch it. The blooding thing was as hard as a rock, anyway I have a stick to do the epoxy, but will look into the stainless steel wool idea as well. I just don't see how you would pack it in from the inside of the tip. My wife and I are heading for Maine for the weekend, I'm not going to worry about it till I'm back. Just for information, I had the clutch replaced although I only have 17000 miles on the car. It was a weak pressure plate not a worn disk that gave me the high pedal. When replaced, the whole drive of the car changed for the better, even the shifting. Not near as hard as before. The mechanic told me he didn't lub the shifter, so I don't know, but I'm not complaining. Thanks again, John | ||

Fiberglass insulation for homes does a good job, stuff that into the tips. Use that or STAINLESS STEEL WOOL, not regular steel wool. | ||

They would probably charge you 8 bucks for a fudgesicle. | ||

I think Ferrari dealers act like they don't know what you're talking about because they don't make any money if they tell you about a cheap, effective fix. When I was diagnosing the problem, I called every US dealer to no avail. They probably have a better markup on a new OEM or Tubi exhaust than a $7 jar of epoxy. | ||

The epoxy trick would probably work just fine. I would also use a Fudgesicle stick versus the Popsicle stick primarily for the aquisition pleasure aspect. | ||

Asbestos is still used today believe it or not. I have tried at several dealers to find a replacement tip or repair kit and they do not have a clue as to what I am talking about. I fixed mine by rolling up a piece of sheet metal and shoving it into the pipe and it works like a charm. My noise was from the two right side pipes. | ||

At Pep Boys there is a high temp epoxy 1000+ degrees, 2000 degrees? The ones that are up to 350 degrees will not work, I know from experience as it blew right out after heating up. I just spread it in there with a popsicle stick and let it dry. It fills in the baffles packing nicely. Unless you study the inside of tips from a close distance, you won't even know it's there. Even if it doesnt solve the problem, it doesn't hurt to try it because the cost is only $6-$8 and one eaten popsicle, actually fudgesicle. | ||

I appreciate all the input. Magoo, I once built a dune buggy on a 1968 chasis. I put custom exhausts on it and the sound was never heard in that vehicle, I know it's not the intake here, this sound is identical to the VW. I took a look into the tips last night. I can see a packing behind the mesh, but can't tell if it thinned out enough to make the sound. I'll have to start it and listen more closely or take some kind of tool and see if there is play in the backing. Doug: I believe that you have the answer or one of them. How much and how did you put the epoxy on the mesh, how did it look after??? Joe: if there is a kit I should be able to find one, but with a quick glance, I didn't see how just the tips could be replaced. Could you get back to me. Herbert: I'd love more info if you have a source for the replacement and how to. Asbestos?? I hope your wrong about the substance. Again, thanks for your time, I look forward to driving down the road with just the ferrari rumble and not a reminder of my old bug. John | ||

The old VWs had an asbestos type of filler/lining inside their twin exhaust tips and after X number of miles it would burn out and a whistle would ensue. I have replace a zillion of them to cure the problem. The 308 has a similar problem and several cures have been discused but no Dealer supplied fixes have ever been verified. | ||

John, the noise you heard in the 70 VW was probably the carbs sucking air. They were famous for their whistle. Unlike the Ferrari, I think it is something else, like a harmonic. | ||

Joe not to disbelieve you but we went through this before with a lot of discussion and no one knew of replacement packing for the exhausts. As a matter of fact I think we were trying to solve Doug's problem until he came up with the epoxy idea,which by the way seemed ok to me. Can you tell us where you got your info. ? | ||

John, Some dealers have a replacement kit for the exhaust tip baffles. If you look inside with a flashlight, you'll see wiremesh. The insulation behind the wiremesh disintegrates causing air to pass throught the mesh holes..thus the whistling noise (like the old VW bugs). Joe C | ||

John, If it is a ringing sound it probably is a harmonic resonance. Have someone rev. the engine slowly until the noise is heard then pinpoint it. Hopefully this works. Exhaut shields, muffler valances etc. are often the culprit. | ||

I had a whistle in my 308 QV that drove me nuts. The fix was to get a really high temp epoxy (2000 degrees) at Pep Boys and spread it on the baffles of the exhaust tips. It pretty much filled in the baffles. Problem was solved. | ||

I just took out the cat and was guessing that it would stop a ringing sound that the exhaust makes. This sound might be normal, but I don't know until someone out there tells me. I had a 1970 VW and that made the same sound as well. Sometimes as I drive along, it reminds me of that car. I would like to get rid of it, if possible. 1986 328 GTS Thanks, John |
