Hi all, quick question. I’ve got an L77 sportwagon with Cam, full harrop 2.5inch system with 1 3/4 headers- has been dyno tuned. Sounds killer and goes like stink. Making the trek to bathurst this year from SA and I wanted to get the opinion of the educated majority that lurks in here. Would it be safe for the car/tune to install either the stock afm mufflers or even vf2 mufflers (would have to have flange mounts) just for the trip to save the ears of my passengers? I’m used to it, but fully loaded with gear, 3 blokes and small trailer- I wouldn’t want to sit in the back for 12 hours
Thanks team JC

The engine sensors will attempt to adjust air/fuel according to the feedback it gets from the O2 in exhaust.

If it doesn't work, then jam earplugs in them

The factory rear mufflers are restrictive and will affect the flow, it won't hurt anything though, just be a bit less responsive. You may use a bit more fuel.
