[Anita]

What exhaust brand should I go wit? I'm not looking to buy top of the line but I'm will to spend good money. And how do I no what size exhaust I get? Like the pipe dim. Prob dumb question but I have no clue.

Apexi WS2...hands down. You can find a used Nismo for a reasonable price on Craigslist sometimes, I love mine. Has a nice, deep tone for a 4 cylinder

i have headers, magna flow and a greedy exhaust 2 1/2 is ideal

What kind of header do u have

[Kholis]

I agree with 06_blkout I have the Apexi WS2 also and it is great, low rumble in idle and doesn't get real high pitched and annoying in high rpms. The size really matters on what kind of headers you have. If you have stock headers 2 1/2in would be ideal if you have DC or OBX (or any other non stock header) long headers that eliminates the cat (catalytic converter) like i do then 3in is what i have and probably what you should go with. Hope this helps good luck!

@Kholis
I just bought my 03 spec-v and saw that it has headers. Could they have been stock. If so, is it worth it to but better after market headers along with the apexi WS2 exaust? Also, do you know what the best performing exaust for my car would be?

[06_blkout]

If there is no pre-cat in the exhaust manifold then it is not stock. Keep it that way because they were known to come apart and cause engine damage.

VRS offers a lot of economical mandrel bent tubing kits where you would just add a muffler. My friend had a 2.5" VRS on his B13 SE-R with a magnaflow muffler and it had a killer sound. I believe the tubing kits where you add your own muffler is $125 for Aluminized tubing and $195 for Stainless steel. Add a magnaflow, and you have a killer exhaust for around $200-300 (depending on tubing), I mean you can add any muffler for sure, but my experience has been with Magnaflow. My B13, when it had a high port with CAI, Header, and a custom axle back exhaust with Magnaflow put down 143.9whp with over 250k on the engine.
