The FGK exhaust AusAccord has is I think one of the quietest full catback systems based on a video I saw a few years ago. We have a thread on exhaust db levels

The Absolute ECU would have been tuned for the performance JDM (200bhp) K24A which has different internals to our economy K24A6 (160bhp). So getting the ECU without the engine is going to be a waste of time. HKS bolt on turbo kit for the Odyssey is the simplest way to increase performace.

Don't think KPro will work on our car, mostly I've seen Unichip Ver Q being used. From what I have heard Unichip+Exhaust+intake change will only increase HP by 15-20. But all this is based on reading what other people have written in forums.
yes i guess your right... whats the point of having a full exhaust and retaining the oem muffler . in saying that what is the FGK brand? i watched a youtube of another ODC with the HKS legamx and on idle he was revving it and it didnt sound too loud ..

hmmm might have to dig further into this before buying any exhaust parts as yet. Maybe just a header to CAT (replace oem CAT) and leave all catback oem. there will still be restrictions but as long as it runs abit better .
