I dont know what ecotech is. its my wifes are. Its a 01 standard model sunfire 2dr. Ebay has been pretty good to me, I bought Some stuff off ebay for my old camaro and had no problems. Maybe I was just lucky. and this is the best and cheapest dual exhaust kit, actually its the only dual kit for a sunfire i have found http://www.magnaflowexpress.com/shop/magnaflow-15762-57.html
Ecotech is the upgrade model of the 2.2 liter. they use to have 2.4 which was in my old sunfire but now they only have 2.2 ecotechs which means they just bump up the horse power a bit. my cars got 150 horses its not much but with the mods you can do you can get that thing as quick as an Accord. The car I really want is a mitsibishi Evolution 286 HP baby hell yea lol. anyways thanx for the web site.
My best friend has a Evo, I love that thing. Driving it down Micco rd in florida( a long winding road) is awesome. The corners that say 15mph you can do 40-50 with no problem. I love the traction and power you get with that thing,being its AWD.
