    Finally, some mufflers I can live with

    These are from Summit Racing, Walker Quiet Flow series.  2-1/2" offset inlet and 2-1/2" center outlet.  Original application is a 500 cubic inch Cadillac Eldorado.  They sound pretty good !  At idle it is very noticeable.  At freeway speeds, they sound like a new, stock Mustang GT.  I LIKE IT!

    Walker Quiet-Flow 3 Mufflers # 21856

    They are alot longer than what is normally used on these cars, but they fit perfect using 2-1/2" pipe system.  I may have given up a few HP, but it was well worth the trade-off.  I can still light up the tires at will in 2nd gear, so I guess it will be OK.

    Money you enjoy wasting is NOT wasted money... unless your wife finds out.

    There seem to be ten diffrent things I want all at once, quieter mufflers being one of them.  I'll be interested in some follow up to see if you can nit-pick them in a month or so.  If you're still digging them, I'm on it!  Thanks for the great info!

    Do you think the Mustang 2.25 in diameter would be as quiet?

    Re: Finally, some mufflers I can live with

    Wonder how they would sound on a 289, with 351 exhaust manifolds and  2-1/4" / 2" pipe? I have standard turbo mufflers and  want a little more sound, so I was thinking of moving up to the Dynomax Super Turbos, but my exhaust shop said they would sound the same. Not sure what to buy for a little more rumble but without the drone?

    The smaller the pipe diameter, the quieter it will be.  I have a pair of nearly new Gibson stainless steel mufflers someone could get a good deal on.  They probably would be ok on a 289 or 302, or for someone who wants a little more noise than stock. Also, a 427 with 10:1 compression makes alot more noise than a 9:1 302.
