Once replaced interference with tuned length on an inline six and lost torque, torque returned with interference type extractors again :)
I'll have to google that LOL. My dad used to have an unequal set on a 6 banger XB Falcon and everyone thought it was a V8 from the sound.

Willy, I stole your idea.

1 3/4" headers. Stainless Steel 3 90° bends and one 45° bend.

Image

And 2" cat back. 2 60° bends and 2 90° bends to complete the exhaust.

Looking good Mate.

I'll be getting a new set made up shortly for my newest Vortex. Gonna go 2 1/4" and put a Hot dog between the Cat and Muffler, same as on my 88 Royale sounds much deaper.

Where is the sound clip?

I have a question! Only dawned on me this week; how much harder is it to change the oil filter now with the long pipe running around the front of the engine? :rolleyes:
Will it ever end!?

You should still be able to get to it :

It might be a bit tight to get any tools in there though ... :(


P.S. - Like your work Ron, I will definitely have to get me one of these now ... :rolleyes:

Cheers, Bantum ...

Yeah...would need a long pipe to use as a socket to twist the filter off? Or just ram a screwdriver through it :rolleyes:

I've never had any dramas changing the filter, you may dribble a bit of oil on the headers when the filter is off but thats the only drama lol.

One thing I have noticed - You'll need to make sure the end mounting plate is orientated correctly so you can get a socket set with extender on it without obstruction ... ;)

Ciao, Bantum ...

Yeah they are handy - I've got one of them in my set ... :)

However no manner of contorting will get a socket/spanner into that space on the inner drivers side if you got the plate mounted on wrong ... ;)

Tight fit ...

Yep - You could use a 'finger' ratchet I suppose, will be even harder to get any sort of torque wrench on it but ... :evil:

Something like one of these :
