well id say either put a turbo muffler on somewhere between the down pipe and the back, and u could also make the outlets a 1/4 or so smaller pipe that helps a little, also ive used these what look like just a piece of tube but they have baffeling in them work really well there made for like small block chevys and the like.

Nice throaty 2.4 exhaust
When I finally install my roller cam, I'm changing just the front part of the exhaust to a Euro "tri-Y" style header along with a modified 3.0 FI manifold.
Right now I'm running a port-matched '75 sprint manifold with standard twin downpipes welded at its junction to a 2.25" pipe, for which I used the original cut off piece as a template. This goes to a JCW 13" body "turbo" muffler and then to a 2.25" fabricated mandrel-bent "over-axle" pipe which continues to a fabricated twin outlet straight pipe in the original resonator outlet locations. I fabricated two chrome outlet tips from four muffler tips (2 round inside 2 ovals) from AutoZone. Throaty sound, not too loud.ConreroGT said:

More help needed
Haven't been on-line for way too long, so first of all Happy New Year to all
My question is on a similar line but I think I've confused myself over my inlet and exhaust manifold.
My GT currently has a 1.9 engine running early Injection and a Sprint Manifold, but I am just about to start the rebuild and will end up running a stroked 1.9 bottom end (2.2 crank and pistons) and then a heavily modified 2.2 head that I have (41/45mm valves, ported and flowed, Irmscher springs, solid lifters, SEXY
Roller Rockers (thanks Gregg aka Samdog) and hotter cam).
I'm likely to use a modifed 3.0 inlet plenium, but may end up sticking with the 2.2 inlet but what I really need to know is can I still run my Sprint manifold or do I need to use a 2.2 exhaust manifold.......if so major problem, I don't have a 2.2 exhaust manifold.
If it is the case that I need a 2.2 exhaust manifold then next questions is, can I use a 2.4 one instead as these or more readily available.
of UK.....needs your help.

I am pretty sure that you will find that all the exhaust manifolds will bolt up as only the postioning of the Intake ports was different.
That being said: A 2.4 exhaust manifold often has an oxygen sensor hole in it for the later model feedback type injection system. I think the 2.4 exhaust manifold has a different outlet flange size and position too.

here's a pic of a Sprint manifold and a 2.4 manifold next to each other. I don't have a 2.4 manifold of my own, and I do not have a pic of just the flange, but maybe this will help some. (the 2.4 manifold is the one on top)

Sprint flange round port sizes
I should add that even though the exhaust ports in the later, wide flange gasket are larger than those of the earlier, narrow gasket, the actual port sizes in the manifolds are identical!tekenaar said:
