3rd Gens inside!!!
I'm interested aswell. I just bought a 350 '88 iroc for a DD 3 weeks ago and I need to upgrade the stock exhaust.
I'm leaning towards the Hooker Aerochamber as the general opinion of those who have it is that it's got a nice DEEP idle and is relitively mild out on the freeway (no drone) but absolutely SCREAMS at WOT. That's pretty much what I'm looking for.
My other options are more expensive but also have good reviews. Borla and GMMG. If I decide to go with one of the higher ends, I might go with the GMMG since I already have the Borla on my LT1.
Anybody have a sound clip of the GMMG exhaust on an 3rd gen?
P.s. I don't care what anybody says, a 4" exhaust is OVERKILL and you WILL LOSE YOUR LOW END TORQUE !!!

The 3 bolts you access to change the plates were a LOT easier to get to on the 4th Gen than on the 3rd Gen. Either way, VERY happy with the setup. The 4th Gen had JBA shorty headers, stock cat, and the Borla and sounded awesome. The 3rd Gen had stock manifolds/y-pipe, cats and the Borla and really sounded great for being just the TPI 305. The individual that bought that car from me did add headers and was even happier after that, but not sure what brand.
So, bascially, I would throw in my vote for Borla. If I had a killer motor, it would do the Mufflex y-pipe and minimum of 3" cat back with the SpinTech muffler.

This is the specific part that I had for my '91 Camaro Z28, 305 TPI, 5-speed manual and single cat. It did come with dual/dual slash cut tips instead of the intercooled tips that my 4th Gen had. I actually liked them and the exhaust shop spent a bit of time making sure the were right were I wanted them. Definitely no one else around here with that on a 3rd Gen.

You can pick up the borla here for $799. http://www.hawksthirdgenparts.com/exhaust
Cheapest place I know of so far.
GMMG is also the same price and from what I've heard, it's one of, if not THE best sounding exhaust. It's also stainless steel. Decisions, decisions .....
EDIT:
Upon closer inspection, I just realised that the GMMG exhaust is cheaper. $799.99 > $799.95
$0.05 isn't much, but it's still cheaper than the Borla.

I've heard clips from flowmaster and hooker but they were ALL on 305's which we all know sound completely differt from the 350's.
GMMG has a sound clip (a really lousy one) on their site but it's on an LS1 so that doesn't help.
I think I'll save up some cash and buy either the Borla or the GMMG simply for the fact that they're stainless steel and will never rust or rot out.
I live in Scarborough, Canada, and while I won't be driving the car always during the winter, I'll still be taking it out so long as there's not 4 feet of snow on the roads
Regardless, they throw a lot of salt out so I woundn't want my exxhaust to rust out on me.I also just found out SLP's exhaust is also stainless and is somewhere in the neighborhood of about $350.
That might be an option aswell.
Quick question for those of you who know,
how difficult is it to run a 4th gen LT1 exhaust to a 3rd gen assuming it's for a single-cat car??
I may just run the Borla from my LT1.
