182
Hi Guys,
I started looking for a decat a while ago, mostly as i wanted a little more noise from my 182. I found that most of the decats on the market seem to be a constant diameter with a large step at one end or the other. My reckoning is that this is going to disturb the flow though the decat, so i decided to design a decat with a constant taper from 2 5/8" down to 2" (standard manifold to standard/rs192 centre section) for better flow charicteristics.
The whole thing is pretty simple and basically consists of a rolled taper with a flare and a laser cut flange (left loose) at the inlet end, and machined flange TIG'd on the outlet. I have a Scorpion rs192 cat back system so fitment of the decat will fit this as well as an OE system.
Im pretty happy with the result as it had been a cheap (just made from some standard 304SS) and simple mod that has changed the note of the exhaust and makes me laugh at the badly mapped Renault cold start even more when it pops and gurgles in the morning.
I have added some images below, let me know what you think.
Cheers,
Ben.
