What Exhaust piping diameter for a Civic D14A8?
Hi guys,
I am looking for a full catback system for my 1998 Honda Civic 3dr Hatch (D14A8 engine). The car is stock apart from a decat pipe and SRI, and I have just recieved my Megan racing manifold too - which looks very promising.
However, I am still running the stock exhaust system from the de-cat pipe backwards (stock muffler, mid-pipe ect.). I have been surfing the net for an aftermarket catback system but have yet to find one in my price range. My limit is around GBP£300 (approx US$570), but that must include the shipping of the item to mainland UK aswell.
My question to you guys is, what are my best options? I have searched this already, but there is nothing on the D14A8 engine, despite it being a very popular model here in the UK. I have tried Ebay.co.uk , but the only options are the crappy Fart-can style systems for about £200 inc P&P! Ebay (USA) seems to list a vast amount of systems, but shipping to the UK is like $250+!! [:@]
There seems to be two types of systems on Ebay, both of which feature a 5.5" muffler with a 4" straight-cut outlet. The difference lies in the piping diameter (2.25", 2.5" and 3.0" (3" is out of the question - Turbo applications only)). Would I be better with 2.5" piping, or would the 2.25" be sufficient? Which would more likely give me best gains in power/sound?
Preferably I'd like the system to have a 3.5" slant-cut tip, but would settle on a 4" if I must. Would my car be too loud with a 4" outlet though, considering I'll be running a racing manifold and decat?
please help guys.... Cheers in advance,

Depends on your plans for the car down the road.
If you plan on turbo'ing or supercharging I suggest a 2.5 inch at a bare min.
If you are just adding bolt ons I suggest a 2.25 inch.

And while you're at it, the ozone layer and everyone's respiratory systems would thank you if you put a high flow cat in there instead of a test pipe.

As for the exhaust diameter, I have been putting a little brainpower into the idea of either building a D16 Turbo engine up from scratch, and swapping them out at some point OR I could turbo the D14. This will however be much further down the line, but is worth taking into consideration as I could re-use the catback for the install. Need to get the rest of the car sorted first though (suspension/brakes mostly).
Oh, and for all you guys thinking the D14 is a small engine - yes, but it isn't exactly slow. The up-side being that it can be turboed with a make-shift turbo setup (T2 turbo) to the region of 200wbhp. Only downside is that there are no turbo kits available for the D14A8, so obiously some experimentation would be required.
