How much difference can I/H/E make?

those are the mods i have, exhaust sound is more important than whatever hp gain you get since its anywhere betwen 15-20rwhp which does really little for your acceleration imho.

I can feel a significant difference with H/E and a chip. Its definately worth the $$$. OF course it always depends on which H and E you have. Some are better than others.

you can say that but the sum of all the parts combined cannot be denied, I think doing almost 108mph in the 1/4 is a really big jump in hp compared to stock.

IMO 15-20 hp with a exahust is very significant especially since the average cost for 1 hp on an NSX is around $100. This and NA1 headers are two of the few mods that are relatively cost-effective. Headers on an NA1 can be just as cost-effective. For less than $2,000 one can easily see gains of 30-35 hp betwen the two at an average cost of only $50-$60/1 hp.

I just threw on a few bolt-ons and did a before and after on a Mustang Dyno. 1991 Acura NSX 100,XXX Miles.

Stock: 208 RWHP

Dali FRP Intake Scoop, Dali Stealth Airbox (Apexi Filter), Science of Speed Header System, Taitec Test Pipes, GT-ROM v5.1. SuperFour F1 Sound Exhaust System (Stainless): 232 RWHP

Gain = 24 RWHP

Quite happy with the results as I didn't quite know what to expect from the SOS headers.
