- 1967 Marlboro Maroon Coupe, 1992 White Convertible
Just finished puting a Corsa exhaust on my 92. Everything went as planned except for some items I'll list below. I'm impressed with the kit. Everything fit and looks real nice. It tucks up nice and tight. My 92 is a convertible and has cross braces that would be a problem if it wasn't tucked up tight. It sounds just as advertised, quiet at cruise, nice roar at full throttle. I actually think it is quieter than stock at cruise and there is no 1500 rpm resonance like before. This is a good improvement in a convertible. I did all the work my self, and have no reason to think anyone would have any problems except for the one listed below.
Now for some thoughts:
1. I used PB Blaster for three days before starting. The only problems were the bolts in the triangular flange behind the converter on the driver's side. I tried to take everything out with an 3/8 air ratchet and they all came but these. Used a 650 ft/lb impact for them. It takes a good two to three feet of extensions just to reach the upper one.
2. This leads me to my only problem and it was with this flange. As I don't have a metric tap set I didn't clean out the threads. All bolts started normally and two went right in. The third galled some how and froze up after a few revolutions. It wasn't cross threaded as it was square with the flange. The end of the bolt was rounded off and the metal was in the threads of the flange. I just drilled it straight through and put a nut on a new bolt.
3. These three bolts were the only fasteners that were not supplied new with the kit. I had three new ones and they had nuts with them so I had an easy fix. Moral of the story, chase all threads before reassembly and use new hardware.
That's my story girls and guys. It was a great weekend......
