What exhaust setup are you using?

This is not too bad but looking for something like this but little more aggressive.

The Spintechs have a more straight piped quality to them than the Magnaflows do... At least to my ears.

Flowmasters can sound good, but if you want performance, avoid 'em.

 

[davbell22602]

Why to avoid flowmaster for performance? I'd put it on my 67F100 w/ 390 thats bored 30 over.

They don't flow as well as others do.

They're comparable to factory mufflers, IIRC.

IMO, if you're just in it for the sound, you'll be more than happy with a Flowmaster.

Dave, is your 390 still a 390?

Dave, the .030" overbore will net you around 5-6 cu. in. IIRC, which is insignificant. It will have nothing to do with your exhaust choice.

I'm just in it for the sound. If I were to find another 67-72 F100 to restore then I would want performance considering making it a street/hot rod. Maybe even drag race it too.

Yes

OK.
