Well I threw in the towel.. I should be cruising enjoying the new sound of my car right now. Instead because of one tiny stupid little nut I'm having to roll around in my old grand am lol... I used to think the 3400 in it was fast, boy have I come a long way!
The mustang sounds like a frickin monster tho not gonna lie! I had to move it back to it's side of the driveway and it sounded just mean since I have it disconnected after the old X. Found out it's a Pypes offside X says it right in the midde of the X. What a craftsmanship difference between the Pypes and the Bassani. Upon closer examination I found a ton of tiny holes in the X that exhaust had been leaking out of. Not one but about 10. I was going to throw the Pypes X on craigslist but after seeing all those holes I'm just scrapping it. That being said on Monday I'm gonna get it up in the air before I leave for work since I work 10-10 tomorrow and Sunday and my old man is gonna chop it off and he said he'll get the nut off. He's been a millwright for almost 40yrs at the ford plant here in Cleveland so I have faith in him lol. Hopefully Monday I'll post good news!
Btw I did try the hammer and chisel method, but there just simply wasn't enough space. I ended up switching to the air chisel and that slipped off and went through part of the X pipes flange fortunately didn't hit the manifold lol. But since I'm hacking it off anyways maybe that will make it easier to break off!
Also tried that style bolt extractor your talking about if I'm reading that correctly. They almost look like easy outs but for removing nuts/bolts? Those didn't work either, to my complete and total surprise...
So it's off to the cutting wheel and sawzall! Thanks for the input guys!
