I have taken my pacemaker(I assume they are 4499s) extractors off my ef Fairmont and I'm planning on putting them on my el gli wagon, I don't want it to be to loud but still want to be able to hear it, at the moment stock exhaust is silent.
Not sure what cat and exhaust would suit.

Any help would be appreciated thanks

redback are pretty awesome.

Iv seen them on eBay, was a bit iffy they might be to loud or have a droney sound, or does that all depend on the cat I use

I put a manta exhaust on my XG ute 2.5” with a muffler, did a cat delete on it, has a really nice not when you put your foot down but doesnt drone, would recommend
