so it can be done without buying the relocator kit, i was pretty sure i had seen a picture of a 4" installed without the kit, i will try it and see, if it rubs to much then i will install the bars. any body else have opinion or has tried it?

It will fit, you'll have about 1/8" of room on top and bottom so if its not perfect, it will rub...

I would buy the relo kit. I have seen this setup installed before and they work well together.

I have the 4inch mufflex on my 89 T/A. It's lowered with a pro kit, stock upper panhard brace. It fits but it's close.

It's the flowmaster single 4in. It sounds pretty good. It's louder than a bitch at WOT.

Can you post a vid / sound clip when you get the system on? I'm very curious about it. I'm contemplating a different system as next month I'm putting on long tube headers and I know my loud mouth system might be excessively loud.
TKS if you can post something.

It has been said a million times, but I will say it again from person experience. Buy some LTs with hiflow cats and either LM1 or 2 will sound awesome, without cats its a little louder and ALL rasp. Puke

Ya I know, and I will not run cats. I was just interested in a catless feed into the mufflex setup. I know, and have experience with the "rasp". Just looking for some media on a set up that isn't so common....don't see alot of people running mufflex...and there isn't any decent sound/vid on ls1sounds.com
