Yea, i dont think many people run 3" exhaust on the dc5 though, i usually just see 2.5", is there a reason why to this though?

sorry for hijacking a thread a lil

Local zorst shop, in Hornsby. Not brain surgery to install a 3" in a Honda.

Because most people with a DC5r use it as a daily, and a 3 inch exhuast is going to be very loud, and if you drive on the high way, VERY annoying. Remeber DC5r dosn't have sound deadening, so the exhuast note is going to echo through the cabin.

I have been in a DC5r with a Buddyclub Spec 4 (or which ever is the really loud one). I was only in the car for about 30min and it turned me off loud exhuasts (reason why i run Mugen)

People from the states have been using the 3" systems for years, and alot of the kswap people in Aus have been also so its nothing new, just that people don't want to draw attention to themselves.

If your after as much performance gain as possible, get the 3", but just make sure you have all the other required mods to make it all work (intake and ECU)

you want to run 3" with no muffler ?

**Nepolian** · 14-06-2008 03:13 PM

Cant get anymore louder

Hope this helps.

BTW 3" may be beneficial if you have I/H and possibly ECU too. On a stocker it may not be as good!

hey mate, did you have to retune your car after you got the exhauste? cause im in the same boat as you, i have i/h/e/kpro and was wantin to go 3'' but was worried bout retune...
