It's all your preference, really. I would do them both at the same time, or if you can only afford one at a time, just save up until you can buy both. And I'm sure you already know this, but don't cheap out on exhaust.

 

^+1....

 

i agree with jwmm04... dont get cheap stuff... always remember da phrase, 'u get wat u pay for' trust me, i saw by experience.

 

you get what you pay for definitely applies. if you cannot afford to do the major 3 at the same time (i,h,e) i would do exhaust first, just a preference i spose.

 

A glasspack muffler will be loud, annoying, sound a little off on a civic, and will drone like hell on the highway. Trust me, I had one before I switched it out for a magnaflow chambered muffler.

Basically, a glasspack muffler relies on fiberglass packing (hence the name "glasspack") to muffle the sound; it doesn't kill off as much sound as a resonating or chambered muffler, so like I said, it'll be loud and annoying. Think Apexi N1 when you think of glasspacks.

As far as the exhaust, I'd recommend 2.25" piping, an actual resonator, and a twin-loop muffler. Incredibly quiet while keeping a nice deep growl.

 

yah dont ruin ur car with a glasspack bro, those sound better on trucks, hot rods, mustangs and camaros, etc. not on civics...dont scratch the itch until u can afford both the headers and the exhaust...thats what i gotta/have to do

 

N1 one is HORRIBLE
