I noticed my 65 Galaxie has an exhaust leak, hole in the muffler, is there a muffler that you can put on a straight six that does not make it sound like an angry hornet. On V8's a smithy glasspack is my favorite and I prefer glasspacks to flowmaster mufflers in general on V8 engines. What would be my best sound for a I6 I have heard Thrush is good, I just dont want that import sound, I'd rather shut it up than hear that, I've listened to youtube but that sound quality is not the best, also how does straight pipe sound and would that be too little back pressure, what is the best sound (closest to V8 sound)
