I really think that the Lotus has had the packing burn out of whatever muffler is on the car. If in fact nothing has been changed on the car,this is really the only logical conclusion. We use Costal Fabricator mufflers on our RR cars and we have to pack them once a year.

Re: Sound Reg #3 5/22/11
John I think your are exactly right. I spoke with the owner at Vision Function and he confirmed some other cars had had the same problem. The mufflers were packed with fiberglass and something else. I ordered a super trap from Summit Racing, but if repacking is a better solution, I would rather go that direction. Can you advise the process of repacking the muffler and where to obtain the proper materials? You guys have a wealth of knowledge. Thanks again.
I am going to get to meet Alexander Borla at their annual car show and open house at the Borla Factor in Johnson City July 8-9. I would encourage a club member to attend. He is setting aside a separate area for local Lotus guys. He owns a Lotus Europa, could be a good club member! and possible resource/sponsor? I might talk to him about a street survival school, with Borla as a sponsor and it would be great if they could work with BMS and ETR and get the club back in at BMS? We could even work with the Carter County Car Club to help sponsor a street survival school? Forgive me just thinking out loud with goal to get back to BMS.

Re: Sound Reg #3 5/22/11
many supertraps also have glass packing that can be replaced.

Re: Sound Reg #3 5/22/11
What I ordered was the super trapp tip only with 12 disks and can reduce the number of disks to further reduce the sound. I will need to have an extension made and a clamp to go secure it to the existing exhaust. I may contact Borla and see if they can provide the materials and or welding.
Re: Sound Reg #3 5/22/11
Supertrapps can be disassembled and repacked. They are one of the few that can. Borlas, off the shelf glasspacks, etc, typically can not be repacked since they are welded together.
I think we tried to get in at Borla for an autocross at their facility but were unsuccessful. Maybe a good word in with someone with the same last name would go a long way. I'm sure there are a lot of club members that would be interested in Borla exhaust products!

Re: Sound Reg #3 5/22/11
Already have a few Borla parts, but I could always use some more. I wouldn't mind another muffler or two on my truck for interstate driving.

Re: Sound Reg #3 5/22/11
is it the extended heat from RR that causes the breakdown of packing on those exhaust?

Re: Sound Reg #3 5/22/11
each sound pulse causes the material to flex back and forth. over time the strands break apart. the broken strands then work their way out the tail pipe as dust particles. I have heard of racing motorcyle riders who have stainless steel strands stuck in their leathers from the bike in front of them.Oberstwill wrote:is it the extended heat from RR that causes the breakdown of packing on those exhaust?

Re: Sound Reg #3 5/22/11
The sound mystery has been solved. Vision Function sent me a new muffler at no cost. Upon removal of the old muffler one could see about a 180 degree crack on the weld going into the muffler. The new muffler is installed and the sound is much lower and the performance seems better and better idle. Thanks, Ted and John and all who commented. Getting busted on sound ended up being a blessing. I can not say enough about the guys at Vision Function. I told them about the problem and asked if they could cut me a deal on a replacement muffler. Jermaine said how about we ship you a new one for free. I any one is considering upgrading a Elise or Exige, the guys at VF are great.
Re: Sound Reg #3 5/22/11
looking forward to seeing that thing back in action!
