So now I will engage my hopefully final, plan of attack! Wish me luck ...<br />I've changed my mind. I decided to use the plumbing pieces agian, but this time I expanded them and bought some special high temp steel stuff to help them stay in. I had to drive them in, so hopefully they will stay in place this time.<br />This didn't work either. They broke loose and began to rattle. I decided to buy some 1-1/2" pipe at the auto store, cut it into two lengths 6" long. took them to a welding shop &amp; had them tig welded into the modded exhaust. This works great! Plug color is good and the sound has been found!<div class="blogger-post-footer"><img width='1' height='1' src='https://blogger.googleusercontent.com/tracker/7915881-109229773163219399?l=exhaustmod.blogspot.com' alt='' /></div>RomeoHotelhttp://www.blogger.com/profile/11652614811776840053noreply@blogger.com0tag:blogger.com,1999:blog-7915881.post-1092152694761686982004-08-10T08:00:00.000-07:002004-08-10T22:25:33.120-07:00It all started when I wanted that "sound". You know the one ... vroom vroom! I didn't really want to spend a ton of green to get it either. I found a <a href="http://www.jackphelps.com/exhaust.htm">mod</a> on the internet that sounded (no pun intended) logically like the one that would do the job. Logical is good right? So I rounded up all the goodies I would need to complete the mod, and began. It worked beautifully. The sound was gooood. The spark plug color was acceptable. I rode into the wind, and had the "sound". Life is good! - I was riding down town one day about 400 klicks after the mod, and decided to crack open the throttle and unleash that sound for a couple of blocks and bingo the upper insert popped out somewhere on the road. I new because the sound changed noticeably. I opted for the chrome plumbing type of insert, and I used the liquid J.B. Weld to hold them in. After the one had pooped itself out, I thought perhaps I had done a poor job of gluing them in. So I took them both out and resanded everything, put lots more glue on them and installed them again. After waiting the specified time for curing, I hit the road again. Pretty soon after they began to loosen up again. I noticed that the glue had become really brittle and seemed to be "baked" it was easy to just chip it off. I decided that there was something really wrong here, and I became determined to solve the mystery. I thought, okay because the metals are dissimilar they will expand and contract at different rates. So then I began to think that I needed some product like silicone that could take the heat, remain flexable, and hold the inserts in place. I popped the insets out once again and cleaned them up for another go at it. This time I thought I had the right product - <a href="http://www.permatex.com/motorcycle/RecProd.asp?automotive=yes&f_call=get_item&amp;item_no=81878">Permatex Ultra Copper</a>. Could this product be the rascal I was looking for. Well it definitely worked the longest, but it too is loosening up. My next plan of action is to Permatex them in place again, and then, using a portable exhaust pipe expander, expand those S.O.B.'s in place. Hopefully never to dwell on it again! As of today I don't have the expander, but it is coming. I will update. <br /><div class="blogger-post-footer"><img width='1' height='1' src='https://blogger.googleusercontent.com/tracker/7915881-109215269476168698?l=exhaustmod.blogspot.com' alt='' /></div>RomeoHotelhttp://www.blogger.com/profile/11652614811776840053noreply@blogger.com0
