Composite Pipe Repair

[Gray E Fowler]

Del-Thanks for the support. I have to admit that I usually think twice 
before responding because it can be very difficult to state an opinion 
without offending someone. And for the record, for the price we are paying 
for composite pipes, we are getting a bargain. We are getting an even 
bigger bargain on composite pattern kits.

Gray.
     Thanks for sharing your observations and stating them as accurately 
as you could. I don't perceive any of your post on this to be slamming a 
given product but pointing out some of the issues that do occur when 
people make C.F. choices for pipes. I myself can't justify using one on my 
4 cycles but will use them on my 2 cycles. 
    This sharing is one of the very reason I stay active and support the 
NSRCA. Thanks for doing more than your share.

I was the person who change the subject of the original post, because in 
no way was I trying to single out any supplier, my comments were in 
general as there are several composite pipe suppliers on the market, and 
in my locale about half fail at the inlet tube due to high temperature. 
Bolly got my kudos simply because they do not sand the outside of the 
pipe, and I have never seen a burned out Bolly pipe, granted only about 10 
that I have seen. And as far as the sanding goes, I think I was pretty 
accurate in describing where that requirement came from, and I still 
disagree with the practice on such a thin structure, but as you have 
stated, to sell pipes it is a requirement. 
I have never owned one of your pipes, but what I have seen has always been 
very light weight, excellent appearance (for what its worth), and good 
engine performance. I also know that more than 2% of the people that I 
know use your pipe in my area experience failure at the inlet, because 
somehow word gets around and they bring it to me to see if I can fix it. 
My point of the whole post was to attempt to educate people as to the 
difficulties of making a pipe that is affordable, looks good cuz it soooo 
important, is lightweight and durable. If your pipes had one flaw it was 
durability when 

1. The header was not just right. 
2. The operator had a lean run 
3. One of those in combination with a hot day-no cooling. 

By switching to a higher temp resin and process you obviously made a move 
in the right direction, and fixed the one weakness, however small, of your 
pipes. In my opinion, nothing I posted was incorrect nor misleading, 
simply my observations of the composite pipes in general.
