^Yeah the MRT catted H is a great piece. I don't think I've ever seen a bad review about one. The MAC o/r H was kickass fitment too. You could have one eye and be dislexic and still install it in 15minutes or less.

 

I had the MRT catted h, and it fit like a glove and sounded awesome. Not sure if it was worth $500 but it was a fine piece.

 

I hear that, on my 89 5.0, I used a Mac system and I mean everything from the front to the rear, it assembled better than the factory one did. literally used hangers for the rear of the exhaust and no clamps, but didnt need to. It was expensive, but well built and all. I just figured since it was the H-pipe only, that I could get away with lower priced stuff. it actually fits, it just needed a lot of attention to get it there.

Any lines on the MIL eliminators? links for my car? 01, 4.6 SOHC?

I did find one set, Are these correct?

just a note, when I went to use this same kit but from O'reilly's it didn't work.

The 2001 Studs are 10mm x1.50.

There is no kit available for them unless you buy the factory one for 60 dollars. Uh.. No.

 

I paid $120 for my wifes Summit H pipe and the fitment was 100% perfect. Sorry about your troubles.

 

I removed my process due it only being an issue on my particular Car/Summit product. It won't do anybody any good that didn't have the trouble I had.

 

That is great news, This pipe was meant for 1999-2004 4.6 only (I think)

 

The car it went on was an 03

 

Oh, so it was perfect?

Guess I just had a bad one then. Nevermind.

 

screw MIL eliminators and get a tuner. i was told get MIL eliminators for the 02 sensors, bought them, hooked them up......and got the check engine light from the EGR
