7) small review (or large if you like) of your over all setup, any tips you'd like to add concerning the combination.
I had the long tubes and a tsp rumbler, but it ended up getting ripped off and bent post y. Switched to the summit catback, and it no longer has the insane drone that the rumbler does with catless long tubes. The summit catback fits very well and has solid clearance, although you may have some install difficulty if your exhaust shop welded on prior exhaust. It has a very nice rumble around town and at highway speeds, and is very mild for such a combination. However it does have one or two issues regarding hangers, in that the drivers side rear hangar is a bit funky to install and angle, and I have yet to perfect the tailpipe alignment to my obsessive standards.
The sound: It is a deep rumble, rather quiet, however can sound rather "tinny" around 3000 rpm for a brief moment, I suspect this could be mitigated with some resonated tips, or some weld in mini bullets after the muffler, but is not a huge deal for me as it is nearly unnoticeable to others. Otherwise, it has a mean growl at higher rpm and sounds vicious.
Other issues: This is likely related to my prior catback installer (I wizened up and installed it myself this time), but I seem to have a mild rattle against the gas tank heat shield on occasion. Its an easy fix, but I am rather busy lately.
8) would you recommend your setup to somebody else.
Most definitely, for the price it is an unbeatable setup, allows serious modification to your taste, such as weld in mufflers, a wide variety of tips, and looks very stock with the muffler positioning. If you have "rude" cops in the area, you can absolutely fly under the radar with some careful driving.
