From the feedback I've read, in this thread and others, they will throw a code for inefficient cat performance. So you can only tune it out.

The RT's apparently don't throw a code, but man are they pricey.

Talked to Mendrel bending in GlenBurnie,Md. They said they are junk and can actually flow worse than the stock V converter...

Any proof they flow worse? I just dont see how its possible. i mean magnaflow high flows are a solid good product

These are Thunderbolts by Truebenz.....NOT Magnaflow...

I got my info from [ http://www.mandrelbend.com/ ] call and ask them..cause i wanted to get those cats. also so i called a quality performance shop for their opinion and that's what they said [junk]

The same company has these in magnaflow high flow cats. (but the link is of thunderbolts) I called them and for $295 shipped you can get magnaflow high flow cats or for $275 you can get the thunderbolt cats.

Im seriously considering these with the magnaflows and maybe picking up a set of spark plug non foulers hoping to not throw a code

As I said in my review in post #9, I liked them overall but be prepared to find better gaskets if they haven't changed what they are sending out. Definitely get the magnaflows. Do EXPECT a code thrown if you are not tuned.
