Hi guys, I have a 89 GT I am in the market for a new exhaust something different. I'm going to retire my american thunder kit. It's been with me for 20 years. My mods are A trick flow top end kit, rebuilt block, h pipe, shorties, I'm looking for something to really set off the stage 1 cam. Everybody has flowmasters in my area so I kinda wanna be different. I saw some flowtech mufflers, Mac, I read loud mouths are just too loud? I really never hears them. To be honest I never hear any others than flowmaster in person. I spent about 5 hours on youtube as well.
