Currently my exhaust is a Dynomax cat-back with a Super turbo muffler. I also gutted the cat. but it is just too quiet for me. I want to avoid the project of headers. Will a flowmaster 80 series make my car rumble louder. Also would I be able to notice any power difference by going to the flowmaster.
I put this here to find some feedback with flowmaster's on TBI engines. thanks

You want power and rumble do the header's. It's not that bad of an install.

Yeah, don't expect to much from just a muffler....ricers do and thats why they throw on 5" piped fart pipes. U can throw a flowmaster on there if u want. I am running a custom 3" exhaust w/o a cat and flowmaster 80 series muffler and Edelbrock TES Headers #6872. I like the sound of it. U can listen to it at my site if u want.

I have the SLP Y-Pipe hooked up to the stock exhaust manifolds going into a Random tech High Flow Cat and into the Flowmaster crossflow. It sounds like I have headers because of the bigger mandrel bent Y-Pipe. It has a mean nasty growl and every once in awhile if I rev up the engine and let it suddenly decelerate, I hear that little rumble pop sound of unburnt fuel igniting in the exhaust pipe just like if I had headers!
