I'm sure meineke would be fine. What i'm saying is you seem to be looking for a cheap solution, just be careful. An exhaust is not just a bunch of stuff thrown together. You can lose power with a bad exhaust setup, A good exhaust setup will give you a little more power increase, a bad exhaust will make you lose power. Some mufflers can be too restrictive. The gs300 has 4 mufflers total as well as a precat and main cat. If you want it to be the same as before and just as quiet, replace the 2 mufflers with oem type replacements. If you don't mind it a little louder and want a few extra hp, maybe just remove all 4 mufflers and replace with 2 new ones. Talk to meinekee and see what options they can give you. Maybe check a few other exhaust shops as well and get some ideas. Also when you get it into the shop have them check the main cat. My 93 was clogged up and shot, They replaced it with a newer free flowing cat and it has helped performance quite a bit. :D
