Standard 2003 EP3 type R (UK spec).
Looking for some advice as want to upgrade the exhaust end to end to try get a bit more horse power and a decent race sound (not too mad!!).
I want to keep the cat because the NCT (MOT) here in Ireland wont pass the car without the cat as they test the emissions. Another part of the test is a sound check to make sure its not over 99db (not too worried about that). Changing from a straight through might prove to be a bit expensive for me over time as I don't have anywhere to store an exhaust manifold and cat and i would have to change it over every year for the test. I wouldn't be confident doing that myself as i'd probably make a balls of it.
The Supersprint system with sports cat would be ideal I guess but its out of my budget and i think the sports cat are hard to get.
So far what has been recommended is to get my hands on a DC5 or JDM civic type r exhaust manifold with the cat, so that will change to a 4-2-1 + cat.
Are there better 4-2-1 with cat solutions?
So i guess the next part will be to fit a decent cat back exhaust to the above. I was thinking about Skunk2 Megarpower R as it has the wider pipes and sounds good, it also comes with a detectable silencer for when i need to bring to the NCT.
Is it possible to use a Skunk2 megapower r with a cat or is it straight through only?
I can also get my hands on the supersprint parts from cat back for a decent enough price but again will that be ok with dc5 4-2-1+cat.
I can also get exhaust pipe and backbox manufactured for a decent price by one of the local honda specialists here, they have a side business building exhausts; or I can get a Magnaflow exhaust manufactured here in Ireland (still have to talk to them to see if they do the manifold + cat too). I heard Magnflow might be able to build a section in the pipe that will allow me to swap out the cat only for a straight through alternative, but again I haven't confirmed that.
Any recommendations considering all of the above?
