Im thinking about buying a dc 4-1 header, a hi- flow cat, and muffler. Should I do this or would you recommend taking the cat out. I need a good shop that will install this for me and do the piping without spending a ton of money. I want 2.25 piping and dont want it to sound so "riced-out" and high pitched either . What brand of header/exhaust should I go with? How much do shops normally charge for this amount of work? thanks

 

do the header(not plural) yourself.

and the cat, actually..all easily done yourself

 

there is no welding? sorry i havent done my homework on this. I had a grand cherokee until recently. dont know much about my 2000 civic. so your saying its bolt on.

 

the header and cat are bolt on.

you will have to get the muffler cut off and a new one welded on..thats it.

 

thanks
