I just bought an 07 honda civic coupe and i wanted to upgrade the exhaust system.
Any suggestions on what sites i could go to and what brands i shuld i look at?

 

LX, EX, SI? i got the SI and i went with the skunk2 70mm. but if you dont want something to loud, i;d say go with the WS2, or the magnaflow. or if you want something loud like me, go with skunk2 70mm, not 60.., and or get the apexi N1. those are nice, but also the loudest.

 

i have an lx. ive been searchin everywhere but it seems like a lot of stuff r for the SI's

 

i had a 2006 LX, i had a muffler welded on there, but it wasnt anything loud, it was actually kinda quiet, got it off ebay, but it was a magnaflow. i am pretty sure the SI catbacks will work with the LX. there the same setup, it's just te SI has a bigger motor, and diff suspension, along with a few other things, but it should work. if not you'll need to fab a little bit by either adding in an adatper, or shortening the pipes. should fit perfect though.

this may sound funny, but i also had 20's on my LX. looked bad@$$

 

pick a brand. bring it to a muffler shop, and they'll make it fit guaranteed!

 

haha kickass =P

anyways ill look it up.. hopefully thats true .. so many SI parts out there.

 

Don't buy a cat-back,buy a muffler then take it to a muffler shop for custom 2.25" piping.

 

i second what evryday getaway said.

buy the muffler, then have custom piping made.

 

that's what i got done, but then i went through stupid stages.....like.... i had straight pipe cat back to megan muffler. then i had to put a stock muffler on cause cops were butt ****ing me. then i put the muffler back on, loud as sin cause it had an exhaust leak. so i took it in today, and got it rewelded...and..............put on a resonator....sounds amazing =) =) =)
