I also bought some 3d printed centre caps for my 2118s. Reason being is that my custom/current ones was so tight fitting them in the wheels, that it lifted some lacquer around the edges. Too much material on the sides i reckon. So i picked up some of
@Louis 3D printed ones. He does various designs, being a all flat design, ones that copy the non sport hub caps with the centre raised, and this design which is like the non sport caps but a flat centre. I opted for this so i can stick on a renault diamond, to make it more OE looking. I have ordered a set of fake wheel caps so i can knick the diamond and place them on the 3D caps. I plan on doing the same as i did before, as in fit them in ally tubing, prep and paint them white, then pop them in the wheels. Once that's done, i'll sand down my current ones and repaint, hopefully with less material. These i'll keep as a spare.
And i also went a bit louder too and bought a decat. The main reason for this was not to add noise/rasp (although i've always been curious since fitting the Yozza) but to get more clearance between the heat shield and the selector shaft. My sports cat must be quite bulbus, as there is no room between that, the heat shield and the selector shafter and no matter how i adjusted it, the shaft rubbed when selecting gears and the sound was pissing me off! Now i have clearance and a bit more noise and i'm happy to say that i think it sounds awesome! Lovely and raspy, no more unwanted rubbing noises and to finish it off, very little cabin noise increase, which i think i was worried about.
I bought the decat 2nd hand after
@frayz linked me to it. It was cheap and the seller was nice and informative and made a easy transaction. Ordered friday, arrived monday. I also ordered a bung bolt too at the same time, which also came monday. I opted for a scorpion decat (although Toyosport do the same design) because i wanted a like for like replacement on my cat. I cant be bothered with modifying my Yozza to make it sleeved or V band, so this way it's easy for me to swap back at anytime, if i have or want too.
So after work, i got the RB in, jacked it up, removed the cat, gave the decat a very quick clean up (degreaser and red scotch and wire wheeled the flange) removed the existing lambda in it and replaced with the bung/bolt and fitted the decat. Took 30 mins or so, so a nice easy job.
The correct way for the cat fitting kit (gap is where the flange is)
The only downfall is the EML light being on. This could be due to the well worn lambda that came with the decat as it was quite sooty. I couldn't remove my one in the cat and i couldn't be bothered to get any heat on it. I have a spare in the garage so i might fit that, or i'll get Alex at AW Motorworks to just map it out, which im thinking is my preferred choice, but for now its clipped into the loom and cable tied up in the heat shield. I will also look into getting better heat shields at a later date as mine are a bit manky and chewed up.
