Hello again, I got an 84 z28, L69 5.0 HO 305 4bbl, 4sp auto. I have decided on the 80 series flowmaster. I have no idea on how to go about ordering for this car. From what people have told me, the L69 has a different diameter pipe and I dont want to call up flowmaster and have them mistaken my car for a regular z28 pipe specs. Here is the link to the muffler:

If you open the PDF file, it shows the sizes and style pipes. This is where I'm lost. Can someone please point me in the right direction. Thanks.

 

Are you looking for just a muffler or a cat-back system? I don't believe Flowmaster makes a direct fit kit for the L69 cars, either muffler or cat-back.

However, Hooker makes a direct fit cat-back for the L69 cars. It comes with a 3" intermediate pipe, 3" muffler inlet, dual 2.5" outlets with quad tips. It looks very nice (muffler is black and not polished like in picture), will not rot out like a Flowmaster will, and sounds much, much better. AND, the price of the kit is only $210, as opposed to a kit from Flowmaster at $50 more, which will require fabrication. Just the Flowmaster muffler alone will require fabrication, or a "creative" weld job. Jegs has them: Hooker Aerochamber cat-back kits. You'll want part number 16822.

 

hey thanks for the reply. i was just gonna get the cat back flowmaster. not an entire new exhaust. this cat back system that i'm looking at is specifically designed for the 3rd gen camaros/firebirds. i'm just not sure which one to get size wise and style that is on the pdf file on the link in my above post.

 

Well in any case your L69's exhaust is most likely the 2 3/4" .... which basically means you can't find an aftermarket replacement. What you can get is the Flowmaster kit of 3" and just get your exhaust shop to get it hooked to the cat.

shouldn't be a big deal.

any reason on getting the flowmaster? sound? just curious if you have looked at the other brands.

 

hey thanks. do you know if i could buy a spacer for that or what? i would like to do the work myself if i could. i'm buying it mainly for the sound. dont really care about much more power. i'm more concerned with a nice sounding reliable sports car that looks good with a decent amount of guts. its got enough power to churp gears when it shifts from first to second, which sounds cool, so thats good with me! i'm easily satisfied.

 

only thing you could do is pick up the catback, and then test fit it, and see whats missing, I haven't done enough exhaust work personally to know.
