With the 4L International fast approaching we took the back box section off from stainless system and chopped off the twin pipes, then mocking up a single up-tilted and slightly left facing tail, using tape to mark the end point, which was then welded onto the single branch where the twin-pipes split from.
For a more classic look we slash cut the end at an angle and then to spice it up ( my idea of course ) we polished the tip and made merry with the blowtorch until the metal turned a blue/purple colour for a 'titanium system look'.
The new tip has improved quietness drastically and still produces a pleasant sound, with pops and crackles like the twin setup
.
Also we fitted a rev counter, into a pod we already had, which has a nice light up display even going up to 10,000rpm ( though it may as well stop at 5500 ).
Unfortunately through erm ... rigorous ... erm ... testing
,it reads around 300-500rpm too low at all speeds so it is rather pointless, thus we will contact the supplier for another item before Thenay.
The car is performing exceedingly well considering the temperatures we have been experiencing of late and has coped very well with an hour and a half of consistent blasting around last night
. There have been zero leaks, high temperatures or misfires to report so that old Portuguese engine is a superb one at that
.
, I think a Renault 4 test would be it's own unique catagory or sure
