why do you need biger headers does it help people are saying i should just get chip which is cool but do headers do anything and what about full catback does that help that much. sorry if i sound really stupid im just trying to learn so if you guys have anything to say about it let me know thanks
im not trying to sound like im better than anyof you guys cuz im not . personally i love the e30 and always wanted an e30 m3. and i want a 325xi for a winter car. im just saying dont expect alot of power from little exhaust or anyother mod. it all comes down to you, whether or not u wanna pay the money. later
Actually, you can get close to 20 horsepower from a chip alone on an Eta.
That's about the only modification that'll make such a difference though.
About the least-expensive headers you'll want to bother with are a little over $250, but you can pay as much as $800. If you really want a sports car (which is not quite what a 325es was meant to be), and you'd spend the dough for a really nice set of headers, then just buy a 325i motor and do a head conversion. There are all sorts of conversations about that in this forum, you might search for them.
