Pick up a Sparrow 63mm or 70-EM, you won't be disappointed. From what I've read the power gains are amazing for a dual exhaust, and both have a nice deep rumble to them.

 

would it be difficult for a muffler shop to replace the tips on the sparrow with those from the OEM? the ap2 cutouts are so big, that those tips look lost. but i like everything else about this exhaust.

 

Not true, especially on an AP2.

I have seen 16:1+ on an ap2 with j's header and 70mm single prior to tuning!!

NOT GOOD!

DO NOT DO IT TO YOURSELF!!!

Invidia = FTMFL on a serious purpose built NA car;

[QUOTE=Audz,Mar 20 2009, 11:43 AM]anyone know off the top of their head which aftermarket exhaust can produce the most power on an NA build. no plans for turbo or supercharging it guys, just wanna make a badass all motor build!!

 

Audz,
Looking nice in your picture. Nice to see a woman driving an S. Sorry no advice on the exhaust. I have a dual exhaust made my esphiler JGT500 love the sound and I feel a difference. No dyno charts though. Sounds like a race car when I punch the throttle. It was affordable. Here are some pics.

Christ Audz. Every freaking guy on S2ki is now going to give you their opinion on the best exhaust for you because of the subtitle of this thread and your avatar. Put a picture of some fat ugly chick up there so I don't have to keep seeing this thread get pinged when I got to MyS2k.

 

Audz if money isn't too much of a problem and you wanna pull some power out of your s2k NA then go with a stroker kit.

this is just an example there are many companies that make these.

Good Luck!!!

 

Maybe you should look into changing out the gears in the car. Granted I have an AP1 and I'm running 4.77's and the difference was night and day. But if you plan on tracking the car you might want to look in to different gearing. 4.56/7

 

no offense.. but i dont think the tips fill in gap very well. too much open space. its either that, or the angle.

 

some needs to put stock tips on that exhaust how many more times do i gotta say it l0l
