My exhaust has some pinhole leaks at the bottom and I found a Manx Muffler (model 20006). Anyone know anything about them. I think I have the el-cheapo Mac mufflers, and not impressed. Really want the Hoske pipes---those sound beautiful (according to youtube research) and heard good things about performance. At any rate, they seem a bit pricey, so considering some alternatives. Would like something that sounds more throaty, w/ some pop. The Macs are boooring. Also, my Mac mufflers have a mounting bracket, and these pipes have just have what appears to be a hose ring type mount. Not sure if most aftermarket mufflers for /5 don't come w/ mounting brackets, and this is normal? Spanks everyone, Nate 1971 r75/5
