theBrit Posted December 1, 2003 Share Posted December 1, 2003 Hi All The short question is, has anyone tried a dual in, dual out muffler under a 240z in addition to a muffler(s) in the rear ? I want this to be as quiet as a regular GM car is with a LT1, primerily so that when I get on it going to work in the mornings the neighbours aren't waiting for me at night I'm thinking about hooking up my Lt1 5sp via dual 2 1/2 pipes with H pipe to two bullet mufflers( short ones might fit) to a pair of super turbo mufflers (and cut the wheel well). Also considering the same set up with a Y pipe to 3" to a single muffler in the back. Any thoughts appreciated. Mike Quote Link to comment Share on other sites More sharing options...
Cable Posted August 14, 2004 Share Posted August 14, 2004 Also considering the same set up with a Y pipe to 3" to a single muffler in the back. Mike I am highly considering doing the same thing. Running 2.5" dual headpipes into a dual 2.5" inlet/3" outlet Y-pipe just before the rear suspension. Then a 3" pipe under the rear suspension and into a muffler in the stock location. This way it will "look" mostly stock and until they hear me on the gas, they'll never know about the 383 under the hood. Quote Link to comment Share on other sites More sharing options...
Guest zfan Posted August 14, 2004 Share Posted August 14, 2004 I am thinking about doing the same thing. My friend did it to his 280Z with 383 supercharged and it was a real sleeper. Mike Quote Link to comment Share on other sites More sharing options...
