hey today I just installed a Bonez Race pipe and a Racing Beat turbo catback on my 89 GXL.
I first thought that's it was gonna be loud as hell, but it didn't turned out that way...
At idle it's pretty quiet. Much quieter than my leaking cat and mufflers!
It's also got that deep tone to it. Doesn't sound bumble bee-ee at all, like I thought it would.

Overall I'm very satisfied with it!

Hey, I guess It's becoming fashionable to Install RB TII Catbacks on NA's. pd day has the same setup.

I had that exact set up on my GTUs I loved it not to loud till I backed off the throttle above 7k!! But now with the Turbo conversion I will have different down pipes and such. I also decided to install a high flow cat to be tree friendly .

What is the difference between turbo and NA RB catback?
is it just the mufflers?

smaller piping i think in the n/a it's 2.5 and in turbo set up it's 3"
