Hi im from New York. this is my first post. I have a few questions.
i was wondering what exhaust can be done to the cadillac eldorado ETC....i see a lot of people put 2.5inch exhaust to dynomax super turbo mufflers. and a 2.5inch y -pipe??? i hope this doesnt sound ricey??? i wish corsa would make an exhaust for the eldorado.i went to the site and it sounds awesome!!!!
my next question is...if i were to get a hi-flow cat welded to the stock pipe , would this throw a code ???? if it does..are there anything i could do to make this code not appear??? i think the hi flow cat would add some good HP right?
also...i saw the intake write-up , my boyfriend said he will help me do this easy mod.
also what spark plugs are good to go with? should i just stay stock , and the same with the wires..or do any of you guys get any better results from going colder or hotter???i dunno
my last question is, can the stock manifolds on the 4.6 motor be ported???b.c if they can my boyfriend said he can do this with his porting tool and clean them up nice...im sure this would add a few horses.
thanks for anyones feedback in advance...it will help a lot.
