Exhaust Piping - Honda Prelude Forum

jsmooney · 05-14-2003, 02:51 PM

Just called meinike about running pipe - they said no one around here ran mandrel bent pipe, so.....it's either "normal" bent pipe or just stock pipe. What size is stock? Any suggestions?

i did research before choosing and dynos showed more for bigger.... I went with 2.5 and I noticed a huge difference in power. (after I and H)

jsmooney · 05-15-2003, 08:08 PM

is 2.5 the ideal size for a N/A lude?

Actually I think 2.25" is the ideal size for a N/A lude. I'm not sure what factors crush bent piping adds to it... maybe 2.5 would be better because of the smaller diameter at the bends?? I don't know... does anyone else??

from what ive read, 2.25 is the ideal size for an NA lude

jsmooney · 05-16-2003, 06:20 PM

what does the N/A come with stock??

i'm feeling lazy, whats the greddy piping size? power extreme or EVO

I'm pretty sure they are the same piping

sorry, I meant what does the Si come with stock? 2.25?

XLerate9 · 05-16-2003, 11:56 PM

no stock is under 2 inches... i think like inch and 7/8 or something.

jsmooney · 05-17-2003, 12:09 AM

so 2.25 would definately be an upgrade?

Greddy is 60/70mm.

jsmooney · 05-17-2003, 12:45 AM

get it the same size at the muffler i am getting - apex n1 - 60mm which is roughly 2 1/4 to 2 1/2 inches

?

XLerate9 · 05-17-2003, 08:12 AM

Yes 2.25" would be an upgrade... and yes get it the same size as the inlet pipe on your apexi n1. The muffler shop will most likely use 2.25" pipe and make it fit.
