2" to 3" exhaust... Worth it?
@rumblefish360
Again;
you totally missed the point.
Here it is again; maybe read it a few times . Maybe you'll get it.
On the street or at the track?
For a streeter;
How often will you be at WOT with the tires Not spinning?
Lemmee guess, from 50 mph to 65 mph, in Second gear.
Lemmee guess with 3.23s and a torqueflite, this would be about 3350 rpm to 4360
I don't think the engine will care, and even if it does, I don't think you could ever measure it, in ET.
So I say;
leave it as it is.
How fast can OP go in first gear? With a stock cam, the shift rpm will be about 5200 rpm. With 3.23s, and 27s this will be about 44mph. At the shift, the rpm will drop to ~3100,
I purposely said 50 to 65, because 50 is 3350 in Second, but maybe 5700 in First , so that allows a lil wiggle-room in the tires, gearing, or shift rpm. You know, in case I was wrong about the cam being stock, or the gears not being 3.23s, or the tires not being 27s. But it is a more than reasonable baseline to
Not be spinning , which answers the first question.
OP gave us a detailed description of his combo, and it doesn't mention anything beyond bolt-ons, so I assumed the short was stock. I don't know any stock 360 shorts that are gonna spin the tires at 3350 rpm in Second gear, so I believe this is a valid scenario.
So then the question is, how much power can the stock 360 short with bolt-ons generate from 3350 to 4360, and does it warrant laying out the cash for a bigger exhaust?
Next; how often will OP be in this situation?, and does that warrant the expense of the bigger pipes?
As we all know, at less than WOT, the 2"pipes he now has is are adequate.
Will the 2" pipes hold his engine back in first gear? Not if the tires are spinning; the exhaust size is not a problem.
Will the 2" pipes hold his engine back at less than WOT in First gear. Not hardly.
And finally, Rumble, you are the guy who constantly rails on me to NOT spend an OP's hard earned cash,
yet here you are, once again railing on me, this time for trying to save an OP some significant amount of money..
