Often I'm too lazy to do anything mechanics wise on the car so why not dress it up a bit...
More coming... and soon will be up to date

After doing a few autokhanas with a local car club I stared looking for ways to decrease times with my limited budget. I began thinking of ways to increase acceleration and thought of reducing the rolling diameter of my wheels i.e. going to a lower profile tyre or even going to 13 inch wheels. The other option was to change the final drive ratio.
After confirming the civic’s FD ratio was 3.866:1, I pulled the gearbox off a spare DA1 engine I had stored in the shed ready to clean up and count ratios before swapping in. Turns out the Integra box had a final drive of 4.066:1. Enough of a difference to bother with? Maybe. So out with the box ready for the Integra one to go in
Dirty box out, clean one ready to go in!
So once everything was back together and after topping up the gearbox fluid I gave the old bread van a wash and a test drive which has proved to show a nice improvement in gear ratios even from a quick zip around at town speeds.

Exhausting work
New exhaust system… "what size exhaust piping should I use? posts on the interwebz" a topic fraught with extremes of opinion ranging from deep scientifically backed up and measured data, to "my mate said 5 inch piping equals 500hp easy" which doesn't really help the average guy who wants to balance power output, noise, cost and not to mention the evil foe (or is it best-friend?) back pressure! I decided upon 2.5 inch in the end which still fits easily, doesn't cost much more that 2 or 2.25 inch, looks tough, hopefully still muffles some dB and sure won’t restrict the power output.
Have gone with an 18" hotdog as shown along with a straight through 16" rear muffler. Going to be loud, but earplugs are cheap right?!
2.5” Redback megaflow offset/centre straight-through muffler 8x4x16". Probably should have gone with a baffled or chambered one (not actually sure of the difference between those two) but will give it a go.
Ended up going with twin tips (1.75 inch up from 1.5 inch). Keeps the whole thing very standard-looking. Even found some chrome tips to add too! This is the new axle-back next to the original.
I know that the benefits of mandrel bends are probably offset by the number of joins, each with potential weld penetrations inside the piping, not to mention cheap mandrel bends not maintaining perfect cross section throughout their entire length. But I really wanted to have a go myself. I must say it's not as easy as I thought it would be! The amount of issues you have to keep in mind is huge. Cutting bends at the right angle, getting lengths correct and rotations of various bends right at each join is tricky. As well as making sure that you clear everything on the underside of the car, including moving suspension parts! But hopefully the finished product is satisfactory! I now know why good fabricators charge an arm and a leg... and they have my respect!
The money shot, sorta… bit wonky:
Ended up going sans-cat for now. Has a nice note to it. Semi-loud outside, surprisingly quiet and not droney (is that a word?) inside. Wishing there was a bit of crackle on the overrun, but I guess the hot dog removes that... so much quieter than I was expecting which makes me happy.
Twin tips need shortening and tweaking a bit and need a shorter rubber hanger for one end of the rear muffler as it sits a bit crooked, so will tackle soon. Was chuffed that I found a pair of chrome tips a little larger but similar to the originals which finish it off nicely.
