I can get this N1 exhaust for 120.... i want an exhaust for cheap since i currently don't have the money for it BUT does this sound good on the mazda3 does anyone have it..will it increase performance or waste of money save up and get magnaflow ...which is what i really want.

 

get some quotes for custom set ups.
just get a muffler you want, and then the ehxuast shop does the rest.
you dont really need a resonator. i took mine out, and it made me ehxuast louder, but deeper and more throatier.

honestly, i went with magnaflow, and after about 6 months, the baffles in the resonator came loose, and rattled like a bitch all the time, and it was annoying too.
so that why i took my resonator out.

 

so your saying I should justdo a straight pipe all the way down and puta muffler on it .....I want performance more than I want sound but then againI dont want it to sound like rice
