I plan on doing side exhaust once I do my side skirts, but I was planning on doing a pro chamber, then dynomax ultra flow ss rest of the way. My friend is doing the same roush side exhaust but he said he's getting a borla kit because you need specific muffler set to run side exhaust otherwise it messes with the performance of your exhaust if you just bend the pipes out the side. Anyone know anything about that?
