My attempt at Exhaust

Hey all,

Great Forum. Just inherited my Father's 92 Firebird with 305 TBI, 105k on the odo. I did a lot of reading here and elsewhere and here is my exhaust plan, let me know if anything sounds weird or if its not going to work..
  • Hooker Headers 2055-1 (I know these are for a TPI setup, but if I understand correctly they will work on my application. Anyone know different? Does anyone know if it has only 1 o2 bung and is it on the Drivers side??)
  • Magnaflow 3" in/out performance Cat
  • Borla 3" cat-back exhaust sytem
This is my first big solo exhaust project so please let me know if I am missing anything and if this should work on my rig. Pic below of my late father's baby:

Re: My attempt at Exhaust

Welcome to the site. WOW, that is real clean and seems to be all original bird. Your exhaust plan sounds good and should work. You will need the y-pipe for those headers.


Sorry to hear how you inherited the car but you may have a nice "survivor" car there.
Post some more pics. How many miles?

Yes, it's pretty much all original. My father loved this car and it's been garaged its entire life. I think drivers seat belt latch was replaced with a grey one and it has a magnaflow muffler, but that's it.

Your father had excellent taste in cars. Very nice bird.

It looks like these come with the Y-Pipe?

It has 105k miles on it, I'll get some more pics soon!

Welcome aboard Biggyniner. That's a great looking bird.


Only thing missing from your list is the beer. I hate exhaust work.

They do come with a pipe but I can tell you that pipe merger is **** necks down to about 2" after the pipes merge before it goes 3"

Re: My attempt at Exhaust

First of all my condolences on your father. Very nice car. I had a Borla once on a Trans Am and it sounded great. Better than any other system I've had on the 5 thirdgens I've owned.

Borla makes high quality stuff. My Solara had a TRD muffler made by borla. After 17 years in NY winters it had zero rust and the polished stainless tip looked like new after a wipe down.

Good to know. I was looking at it closely, it looks like one pipe Y's from before the muffler and becomes the passenger side pipe, without going through it, while the drivers side tip does.. I can't be seeing this right...

You are seeing it right. The borla carback has tunable sound you add in these disks and can tune how loud it is without sacrificing power

Oh, that is crazy! I listed to some sound clips of the flowmaster kit and I'm going to keep that one in mind too, it's also almost half the price...

I cannot reccomend that they are 1/3 of the quality and every one I have ever put on a car for someone I have removed a year or two later. Although if you want to save some cash MagnaFlow is good.
