Since i bought my Dart it needed a couple things to make it a driver, turns out my lower control arm is bent on the drivers side and found one for replacment and also got new rotors calipers master cylinder and booster with new drum assembly all on the car now it stops like new again, turns out the master cylinder on the car before replacement was for a all wheel drum car but mine is a front disc car haha also installed a new Carb Edelbrock 600cfm performer 4barrel and runs a like a champ fires first crank everytime now just need to get the suspension done and i have a good car then cosmetic work is next along with exhaust i was thinkin of doing a Edelbrock SDT muffler 3 inch dual side exit exhaust, i am open to ideas on what to get for an exhaust system.

 

I would just go for the 2 1/2 system. you can buy them through summit racing.
Maybe a set of hedders they flow much better than the manifolds. (be warned though, they can be a pain to install especially on the driver side;you get what you pay for with hedders). crossover pipe would be a nice touch but would make it quieter, more HP though. 3 inch pipes are really not that necessary unless you got a really crazy big-block. 2 1/2 pipes are plenty big

 

Yeah i got the stock manifolds which have a leak somewhere haha but is there a particular set of headers that are best with Mopars? my 318 has a mild cam in it with a good lope sound to it i just want to pronounce it a little better my stock exhaust is scrap its in bad shape with lots of leaks lol

 

Hookers or hedmans are good for small blocks.

I have a pretty good running big block and I run 2 1/2" out the back.. You'll be perfectly fine with 2 1/2

 

Thanks i'll look into those headers to buy once i get a system installed
