Welcome, and GREAT Galant!!
You should be proud of ALF's original condition
If the exhaust isnt leaking or rusted, keep it.
It makes it look like the Sundays Bowls car, which is way cool!
But if you really wanted to change it, maybe start with a 2" system from the engine bay fire wall back.
Save your money and pay attention to the Suspension and brakes
Check the Galant section, Builds, and Suspension sections and you will see loads of upgrades that you can do
and usually not too expensive
Look after Alf, he/she is a beauty
Cheers Dan
Yes, dad said something about a 2"... :-)
Yep, suspension needs work.. as do brakes

Alrighty, shall check it out later

Oh, and Alf is a "shim"

Why ARE cars always "she", anyway? o.o
I'll admit right here and now that I prefer to think I'm drooling over a fella, rather than another female... <.<
But I'll stick with "shim". :-)
It's like male and female at same time... but neither, too. Like God. XD
Haha.. just chatting to a mate about "Him", "She", "Shim" & Cars right now, and his definition is thus: "Shim"; being a supreme being of awesomeness which is neither male nor female but walks among both worlds as it pleases. ^_^
