You're making good progress, Derek.

Are you aiming to be ready in time for Ellerslie?

Colour combination looks to be working really nicely.

They're the classic American glass-pack muffler - http://www.cherrybomb.com/
Also rather poor from a sound and performance viewpoint.

opinions, opinions, just love them at times....

sound - yeah they are loud - if you want a quite muffler don't by one of these

performance - if you want a degree of back pressure from a muffler don't but one of these

There's opinions and then there're numerous testing results - loud and high flow resistance - especially the versions with the press cut centre, but even the drilled smoothbore aren't that good.

1256cc with twin 45's, headers, 2" straight through exhaust and a 10 inch long straight through at the rear (basically a resonator)........not that worried about resistance
its just the same stuff done to Chevettes and Minis for years back in the 80's when it was all about the "rip"

I reckon a great setup for a motor of this size would be no resonators and a motorcycle glass pack on the back. Works great on bikes so why not?

funny you say that, I came across some sites where the guys were doing exactly that, one guy had an awesome looking titanium rear muffler on his car.

Cool!
I have a big 400mm carbon can on my XJR and with new packing it gives a really nice mellow (yet still raucaus) sound. I think a similar setup would provide really pleasing results on a 1300 car with suitable backup modifications of course .

There's a couple 2" offset inlet, centre straight outlet (or the other way round) full chamber mufflers made that are a perfect fit for the Chevette's main muffler location (may need the unused huse mount cut off the torque tube, though) that are quiet and very low resistance to airflow - one I had could be seen straight through yet was also very quiet cruising or flat out without any other muffling. Unfortunately, I can't provide the part numbers.
While it is a question of taste, regarding the sound, I'm not sure the WoF chaps and Polis would agree on that 'taste'

Chad, many moons ago a mate had the rear muffler fall off his Holden V8 that had a reas traverse muffler - he replaced it with a spare from an old triumph twin - worked well!

Re: the muffler, if it's needed, centre/intermediate muffler for a Transit seems to ring a bell.

getting the Chevette home after painting (state of the art spray booth)

my youngest daughters E36 coupe failed its WOF today on a rear suspension bush and a leaking shock, so I convinced her that if she wanted it fixed properly she needed 4 new shocks.
so a little bit of retail therapy for me and 4 hrs of work from me and her brother Ryan and its got a nice set of B8's with Jamex springs all round, so its now sitting like an M Sport should.
shit its seriously hard now, cant wait to take it for a test drive before letting her near it
