Cat-Back Exhaust System – 88-91 Honda Civic Hatchback Si – 2.25" T-304 SS – Burnt Tip 4.5"

Give your EF Civic Hatchback Si some serious sound and style with this full cat-back exhaust from Speed Daddy.

Made from polished T-304 stainless steel, it’s got a 2.25” inlet and a fat 4.5” burnt titanium-look tip that’s slanted and rounded for that aggressive JDM look.

Everything’s brand new, direct-fit for 1988–1991 Civic Si hatchbacks.

Just a heads-up: doesn’t ship to CA, ME, or NY due to emissions regs.

But if you’re outside those states, this system is a killer upgrade.

Sounds mean, looks clean, and won’t rot out.
