I have an old Monza 4 tip muffler unit laying around. It's not in all that bad of shape but I know there are better unit - though this is free to me and maybe good enough for now on my driver. However, I thought maybe it could be improved upon.. so I was considering cutting off the mufflers and their heavy double tip sections. The idea would be to try for a descent sound while also lightening the unit. Are there any suggestions for more modern and lighter boxes that I should look in to, for replacements? I'm also thinking of adding a much simpler 2" single outlet on each side - for additional weight savings. Any ideas or comments? .. maybe just don't bother?

OK cool, thanks for the pic. What mufflers are you using? Like the sound? Got a picture of what was done with the tips on your conversion?

My Anza was a lot heavier than this Monza. this Monza is a 1975-76, so not the four pipes but two. I converted it to four using parts from the Anza but then got one of Marty's headers instead. Big tubing on this version 2.5" to fit the header but stock it goes into two 1.75" tubes (3.5") and four 1.25's (5.0") out, but still quite compared to the Anza. Much quieter.
Not sure which one you are starting with but this was quiet enough to just leave the mufflers alone.
