SiR Exhaust on a 98 EK?

Does the SiR exhaust simply bolt on without any modifications to a 98 Civic Si? Will it line up properly and look ok?

i believe you will have to slightly shorten it because everything is the same just the sir is a little longer with the trunk. probably haave to chop a few inches off before the muffler.

A 99-00 SiR catback section (midpipe and muffler) will bolt on without any mods. I had one on my 98 Si and it fit perfectly. It sounded a little throatier, but not really loud at all.

An Integra Type-R catback needs to be modified to fit though.

I'm assuming from Axle back (using stock midpipe) the muffler would bolt on too then?

they follow the same line and bend the same way from the header back.... the only thing that wont work is the header obviously because its a b series.
Everything else is bolt up no mods.... maybe bend a hanger or something!

The muffler will fit fine. As mentioned above, they follw the same path and bol up the same way. The SiR exhaust is just a bit bigger in diameter then the stock Si exhaust.
