My wife has a 1990 GT convert, which serves as a weekend/errand toy for her, and it's completely stock except for the tail pipes on it. It's in great shape, and we really want to keep it close to factory condition.
I went to get it inspected the other day, and both tail pipes are rusted with holes, so they failed it. we've talked about swapping out the catback anyway, because whoever replaced the pipes previously installed tail pipes which exit under the ground effects, and this has caused cracks in the ground effects paint over the years (when exiting a steep driveway, the pipes hit the road and contact the ground effects).
So we want to replace the catback with something that is not too loud, but adds a bit of rumble; and also want to go back to the stock style tips with the turndowns just behind the ground effects at the rear.
So I'm looking for a good catback (preferrably stainless) which won't drone at any RPM, and has just a bit of rumble to it, but not really loud.
The Flowmaster 50 series seem to have the right level of rumble-to-loud ratio, but I'm concerned they will drone. To prevent drone, do I need 2 slightly different sized mufflers? I read somewhere that a manufacturer of catbacks did this to prevent drone ....
Here's a pic of the back. As you can see, the rear bumper and ground effects need repainting, but we're going to wait until the tail pipe issue is worked out.
And here's an old pic of the car when we 1st brought it home, before a detail and the new top was installed:
