1972 351C manifolds
#1
I am thinking stock exhaust is the way to go. My car is loud, the full length headers hang too low, it is hard to tune and the car does not drive as well as it can. I need some headers so I can buy a stock like exhaust with crossovers and sensible mufflers so I can enjoy driving this car. It is so loud I can't hardly hear when I am driving. I was thinking about getting quieter mufflers but the long tube headers and lack of crossover is made for racing and I don't race. PM me with price and condition of headers please. I would like to move really fast on this since it is a daily driver and I need to drive.

Bright lime 72 Mach 1 with 351C 4V, with summit 600 carb(have a Holley too), Edelbrock dual-plane manifold, Hooker headers, 3 inch exhaust with flowmasters, 17 inch Eleanor wheels, FMX tranny, A/C, P/S, front disks and 350 rear gear. Drive it to work every day.

The exhaust ports are quite a bit bigger on a 4 V head so I suspect they are. I see 2v's and 4v's on EBAY. I would like to try here first and then move from there. I will do something because the noise of my exhaust is simply unacceptable.

Just the muffler change and adding an H-pipe will make the most difference in noise reduction.
The swap to manifolds will certainly help with ground clearance issues.
You'll like it.

Are your heads 4V or 2V?

The manifolds are different between the 2V and 4V. The 4V one's are quite a bit more expensive and it is pretty difficult to find the long passenger side that has not cracked.

I suppose I could just have them chokes the tubes down and add a crossover as well. Not a big fan of the clearance issue but I did lower the car to look better with my wheels.

I have the hooker comp headers http://www.summitracing.com/parts/hok-69...el/mustang
Mated to the pypes exhaust system http://www.summitracing.com/parts/pye-sf...el/mustang
My car is lowered too & no problem with the exhaust hitting..for a very quite system I would delete the pypes mufflers http://www.summitracing.com/parts/pye-sf...el/mustang
Get stock mufflers from these guys they make them
http://www.precisionexhaust.com/#!catalogs/c2kw
OR you could get the complete system from them..call them.. speak to them... they will set you up with a nice quite stock system..

I have a set of long tube headers on mine as well. I tried the pypes exhaust and did not like the fit. A lot of people do, but I had some clearance issues with my 8.8 rearend. I went to a custom exhaust shop and got a beautiful stainless exhaust from the headers back with an x pipe and magnaflow mufflers. It is whisper quiet inside now and I love it. Still throaty when you jump on throttle but at cruise rpm its nice. I also installed electric cutouts too, just incase I want open headers LOL!!!! They are cool too!!! All that, minus the cutouts, for about $75 more than the Pypes kit from Summit. My old exhaust was straight pipes going into old school cherry bombs with a small 2 inch pipe.....HOLY HELL LOUD!!! Cracked enough to make your ears hurt.
