Same boat except I have a 59. Tough decision. What are your options and what are you leaning toward?

I personally have my appointment set for this coming Friday, I am super excited. My options are dump behind the rear tire (factory option) or go straight out the back. I will use 2.5" pipe (or at least it seems that way according to my measurements) and will use angle cut tips since I want to do flame throwers some day. My exhaust guy recommended dump behind the tire like factory to avoid scraping on driveways and dips. If it weren't for my flame thrower idea I would likely follow his advice.

When I bought my car it dump in front of the rear tire and I hated it. It was really loud. For muffler options, my guy had a hard time finding a longer performance based muffler (I wanted to keep the crackling affect to a minimum) 18" seemed to be the longest we could find in Magnaflow. The dimensions have to be pretty snug since they can hang fairly low and there isn't a terrible amount of room under these cars. Glass packs were suggested but I had 0 interest in those awful noise makers.

So you've got some options but I guess it just depends on what you are looking for.

Hello;
Same Boat Different car. Had glass packs (cherry bombs) now I'm going from newly installed headers. Don't know about cross and H style pipes (I better do some comparison reading) But got a pretty good price. Trying to keep everything tucked up higher because car is really low and my past exhaust used to scrape everywhere!!

When I purchased my 62 Impala the tailpipes exited straight out the rear with chrome tips like we all did in the 60's. The rear trim was pitted from the exhaust gasses. I have since gone to completely stock dual exhaust system without any problems.
