hey guys whats some of your opinions on the best header, cat (test pipe), cat back exhaust, and intake for a 99 ex

 

bump

 

THIS might help

 

or this, this, and this might help... come on, youve been here long enough, you should know how things work around here

 

these are definitely two different things. i recommend a high-flow catalytic converter. test pipes are illegal, ruin the air we breathe, and only give you 1hp more than a high-flow cat. you'll find this interesting: https://www.hondacivicforum.com/m_279591/tm.htm

 

i had a magnaflow cat back, a stainless steel header i bought at a swap meet, stock cat, and an aem short ram, on a 2000 civic ex,and all together the car sounded really good and the exhaust fit awesome.
