Hello, I am new here, and I own an 03' V6 coupe with the 5 speed. I could use some advice on mods. I was thinking of a dual exhaust (bolt-on) and short shifter and an ECU chip. Any recommendations?
Don't do the chip until you get some more mods. It will be literally useless. You won't get much more power out of a bolt-on dual exhaust. (reason being is you still have the point of constriction which is what you're removing when you do a dual setup correctly.) Get yourself a CAI to go with your dual exhaust. Check Ebay. There is a constant debate on which is better...a $200 MAC intake or a $50 Ebay intake...I have one off ebay and it works fine.
Try under drive pulleys. Thats your best starter engine mod you can do (unless you add a blower, in which it will be a waste of money). (adds power but also saves you some gas)
3.73 gears with a t-lock. (adds speed no increase in mpg)
Those are the basics. Short shifter won't do anthing but help you shift a little quicker if you're racing...i'd personally do the other mods before that. They will actually add power or accel speed...that wont do much unless you're racing (and btw street racing is banned off this forum FYI)
bolt on Y is fine for looks and if you only plan to throw on a couple bolt ons and dont ever plan to care about how fast you wish to make the car, they gain decent hp/tq but its just as cheap to convert to true dual exhaust in the end.
lol, wtf S pipe, got with true dual, don't worry bout X pipe cause the opposite cylinder on a 6 fires right after the other, shouldn't cost much really, most shops around my area wouldn't even charge you cause it's just too easy
the only reason an X would be helpful is to keep some backpressure there... its not needed just run a pipe on each side it will sound alot better at idle with no H pipe.
