I don't know how I feel about mac. I have there h pipe it was installed a year and a half ago and its completly rusted through where it clamps to the second part of the midpipe. I'm sure it wasn't installed professionaly and I think there was a leak there causing the rust but I'm not to sure I did not own the car at the time it was done. I know a lot of people run bbk so I'm thinking they have to be decent and there pretty much the cheapest out there.
As for the long tubes I'm going to be installing the headers and such myself. So I need the easiest to install lol and that would be shorties. Plus my car is a dd and lowered and the quality of roads in jersey aren't that good so I don't want to run into any problems with botoming out. Otherwise I would go with long tubes.
I'm thinking about changing my catback aswell. Nothing wrong with it, its a mac catback. I like the sound of what I have now and it will def sound better with headers and a leak free system. I'm going to wait until I have the headers and mid pipe installed before I buy a new cat back so I can see what it sounds like. But I still think I'm going to want a much more aggressive sound in the end. Any suggestions on a cat back? What do you guys think would sound the meanest with my setup? I want both loud and aggressive.
