Opinions on exhaust
When I bought my car it had 273, Hooker headers, 2.5 exhaust, Flomaster 40s, and ran out the back with no exhaust tips. The very first thing I did is removed the tail pipes from the mufflers to the back of the car. Fortunatly they wasn't welded but bolted. That made a big difference in which it made the exhaust tone deeper and louder. It sounded like a big block. This what I recommend you to do ... is to remove the tail pipes and "dump" it before the rear axle. I hear a lot of people say "Don't bump it the exhaust fumes will come back up inside the car!" I think this could happen if the car has holes in the floor boards, trunk, etc... but I always Dynomat my cars and make sure everything is kind of air tight if you know what I mean. I don't have that problem.
I now have a 360, TTI headers, 3" pipes going into 2.5 X-pipe, the same Flo 40s, dumped. The X-pipe WILL quieten the exhaust down a great deal.
Electric cut outs. I have one on my 03 Dodge ram and it worked fine for a while then started leaking. They accumulate exhaust residue around where the butter fly closes and then it does not seal very well. Be prepared to clean it every so often. I had to replace the electric motor once. More money. The switch for cut out is not like a light switch where on is on and off is off. I have to hold the switch until the butter fly closes and same thing when I open it. The instructions say that "Don't hold the switch to long on the motor will be damaged!" They say also to "Bump the switch instead of holding it until the cut out closes." Well I know for a fact that is not what damaged my motor because I would shut the truck off so I could hear the electric motor and bump it closed until the butter fly closes. I did my best to keep from damaging the motor another words and still had problems. I couldn't imagine having two of them on my cuda. They aren't worth it in my honest opinion, PITA! I have the QuickTime electric cut out so if shopping for one I believe I would pass on theirs.
If you want a cut out type system talk to VOETOM on here... he's got some great cut out type mufflers. They are sweet!
I believe if you yank those tailpipes you'll be happy with it!
I've set off a few alarms! LOL!
Good luck!
