Real tech discussion on design, fabrication, testing, development of custom or adapted parts for Pontiac Fieros. Not questions about the power a CAI will give.
How'd you route yours? 2-1/4" -- 2.5" mandrel doesn't exactly strike me as having much in the way of restriction...
I went off the factory manifolds with a 2.5" mandrel bent, out the back, then made 2 sharp turns into the muffler, and then had 2 mandrel bent 2.25" outlets to the Caddy tips. Very similiar to this one done by Blue Shift. Mine doesn't have a cat, uses MUCH uglier welds, and uses a Spinteck muffler. To be honest, the performance between your's and mine will probably be about the same. But mine weighs less, was easier to build, and was cheaper. Your's will be quieter, and probably sound a bit better too.
That midrange resonance (I know, this is an LT1) is what I want more of, and it's more civilized than the other flowmasters which I usually find too raspy.
The spintech was a VERY close second... What cinched it was that I could get the flowmaster 80 crossflow locally, and for less... :salute:

is it the same shape as the stock fiero one? i'm looking for a replacement for my dad's 2.8 turbo setup
The Flowmaster80 is the same shape as a stock Fiero;
Inlet on the bottom, balanced outlets on the top., 2.5" in 2.5" out.
Thing is, it's about 1-1.25" longer on both sides, so some massaging is going to be necessary. Likely, I'll be trimming about 1" off the outlets, and I WILL have to relocate/modify the stock spring hanger brackets a little.

Ok, so that's a single peice right down to that 90º bend. My question is how should I attach it to the flex coupler?
I bought one 'cos I figured I wouldn't get any pussy if my exhaust shatters every time I hit a speedbump. But I do want the system to be somewhat sectional, so I can take it apart if I need to.
The flex coupler fits OVER the 1.5" straight at the end of the elbow; I was thinking just using a u-bolt to lock it down.
Trouble is, I have never had much luck with those stupid things holding together. I was thinking of perhaps the U-bolt, and then a couple of spot-welds to stop it from coming apart. Not quite quick-release, but easier to take apart than having to cut through a $90 flex pipe...

I never said it was, in fact I said very clearly that it wasn't and I gave proper credit to the owner.
My 2.25" outlets did not fit in the factory U-hangers, so I pulled out the hanges. My exhaust is light enough that just 2 bolts on the downpipe hold it without movement or leaks. I've never liked Flowmasters on the 3.4 DOHC, in fact I hated them. But I canc learly understand your side, as it was probably a lot cheaper, and didn't take 3 weeks to get.
