Which is louder

Which is louder on a 1996 GT. It has a UPR O/R x pipe with flowmaster delta flow 40's weld ins which is loud. I'm thinking of getting a Bassani catback but i don't want it to be any quieter than what i have now because the volume now is great. What is the volume difference at idle and while accelerating. Also what about magnapacks.

Thanks
 
I think at idle, they'd all be about the same. Magnapacks will definitely be louder than the flows at any rate. And I've only heard good things about magnapacks :D
 
bassani is top notch quality, flows rust. its as simple as that, they just dont have the quality in materials or in fit. The sound is great, i do not think you will be dissapointed. I would make sure to have straight through mufflers behind that X. Nice little addition to the bassani after cat are the baffles, they are small, but they do change the sound to quieter and add a little burble it seems.
