Big Exhaust Surprise-Anyone Want These?

Y'all here on the Forum convinced me to move up to the GT500 exhaust

I did and, thanks for all the good info here, I am VERY HAPPY !!!!!

The surprise came when I removed the old axelbacks, which APPEARED to be factory stock.

I bought this car with 6,900 miles on the clock and what seemed to be a stock exhaust system.

The cans looked the same, the rolled tips were factory, but surprise, surprise, surprise, when I removed what I thought was the factory system, the two front factory hangars were not on the mufflers, (lucky for me the brackets were still there)

From the engine back, the main exhaust system was being supported by the engine connection and a single rubber rear hangar.

The cans were smaller and lighter, and had no markings on them.

The cans were simply welded to the factory tips and factory curved inlet pipes, factory sticker still present. The wire feed welds were not the cleanest either. There was evidence of some weld splashing on the undercarriage.

The curious thing was there were two rusty plates welded to the subframe above each muffler but had been cut off. I painted them to protect from rust before I thought about taking a picture.

If these mufflers are anything special, I'd give them away for the shipping cost, however I suspect the previous owner traded this white GT in at CarMax in Gastonia NC on a used red Mustang convertible and swapped whatever upgraded exhaust was on this white GT.

The weld on the subframe tells me that the work was done at a local muffler shop.

I LOVE the car and love the GT500's - am really pleased, thanks guys.

Any ideas on what I removed?

Anyone want them?

Should I save the tips?

I'm stumped and I've owned a bunch of 5.0 mufflers. You got a pic of your new setup?

Lol. Without any rear hangers they are pretty much scrap. Those are two different mufflers. That's what came off?

I'm putting these on today.




Full T304 race bullets.

No pix yet.

The new setup is the GT500 axlebacks - AWESOME.

that's the GT500 in the photo with the rag taped over the tip to protect it during the install.

What came off her was cobbled together with factory pipe and what appeared to be factory rolled stainless exhaust tips.

It's still a mystery, unless its as simple as the previous owner going to a local exhaust shop to put SOMETHING on her to get through the trade in (on a s197 red convertible)

========================================

no, I was comparing the GT500(rag wrapped tip) to what came off.

Yours look like candy !

My son's old 2006 pony had a muffler just like that. Maybe it is a 2005 to 2009 muffler?

The 05/09 mufflers had single wall slash cut tips.

these are rolled and have a drain hole at the bottom.

if anyone wanted these I'd give them away for the shipping, however it appears that they may not be of any use to anyone.

Those look a lot like MBRP's: http://www.americanmuscle.com/mbrp-p...ck-1114gt.html
Their tips are not welded to the cans, instead they clamp on. They also have the MBRP logo etched on them. The previous owner may have had the original tips installed to retain the factory look.
