Besides not being American made, what is the downside of using speed engineering versus something like TSP or Kooks. Also would it be possible to buy high flow cats from another company and use on the speed engineering long tubes? If possible which high flow cats do you guys recommend?

i run eastern catalytic high flow cats with my speed engineering headers. they're great and cost $75 a pop. magnaflow highflow cats also work just as well and are similarly priced.

I think they are great. They will surface rust though. I’ve had them on my car for over 50K now with no gasket leaks !

I just bought/installed these about 3 months ago on my 2012 LS3 and I'm pushing 425 to the wheels on a mustang dyno with Airaid CAI, and AMT Catback. Fitment was perfect. The only negative I have to say, was that I was unfortunate the have the exhaust leak at the connecting pipes. Nothing some good ol' welding can't fix.

So if I use the off road pipes (No cats) how do I install my o2 sensors and not get any CEL? I am considering these since I have a Kraftwerks supercharger already, I dont need cats for emissions, but I dont want the light coming on

a tune will get the light turned off. a tuner can tell the ECM to not worry about the down stream cats. thats what gets rid of the light.

Just bought these. Only complaint is the dreaded header spacing. Going to need to put some dimples in there.

Coat to install
Any ideas on how much people have been charging to install these headers ? Approximate ..I might pick up a set
But so far the quote I got here was $350 for the install . Seems a bit high .

I was quoted 400 and 350 by two different places here. Despite being mechanically stunted, I did them on my own. As long as you can get the car up high enough to slide them in, it wasn't bad. I did have to buy new spark plug wires as I pulled one clean out of it's boot though. It was also fun to start the car running open headers too, before I connected the exhaust. The neighbors probably weren't so enthused about it, but I sure was smiling. |

Question
I am in the process of getting the speed engineering headers . For the people in this group that already have them .DID you order the connection pipes to the xpipe from speed engineering ? Or did u go with a different brand for the connection pipes . Also a few people mentioned that they purchased the connection flanges from summit since it was a better fit . What about the gasket ? Speed engineering as well ?would love to hear some more detailed information regarding this setup. I know my flowmaster catback has 3 inch piping . Please advise GURUS !!!

For those of you that have installed these headers specifically, did you have to use O2 extension cables?
