I have them to, Very nice headers. I have an SLP drive shaft loop, and a BMR Torque arm. Fit nice with those, installation was fairly easy. Get em' you wont be dissapointed.

Where do the rear sensors mount to those headers & are they tuned equal length. Also , how much more ground clearance do these have as compared with the header with the second most clearance ?
And finally, does a 2002 require block-off plates ?

I have them. The only thing I don't like is the 4 bolt flange. It's a PITA to get to the top two bolts on a C5.

I ask is that the flange that connects y pipe to the headers?

Does it have to be those specific cats? You can get magnaflow 59959's from EAD performance for $90 each. They're a small bullet cat and I'm sure they flow just as well if not better.

Interesting how I haven't read many reviews on these headers yet everyone seems to like them. I guess because of the price?

the price ain't cheap. 2300-2500 for headers and catted y

I don't know where you got that from...

mine was only $1200 for the whole kit (everything included).

Yeah, I think you may have thought the $1200 was for the headers only and then added on the price of the y-pipe?

The only "problem" I see with these headers is that the flanges on the headers won't allow you to run other y-pipe if you wanted to.

Plenty of people have them, just not nearly as much as other brands like QTP, Pacesetter or Kooks. Dynatech people come out in full force when a forum post is directed to them. They're typically a very silent group. I've never heard of a single bad review of the system. It's a shame it's often neglected and swept under the rug. It's really not a bad deal and I hear the fit and finish is fantastic.

Not an F-Body, but the Dynatech system on my GTO has nice pieces and doesn't leak at any of the flanges, FWIW.

I looked at this system very carefully last year.

Things I like about the system, based on what I think I know about it.

• Stainless steel
• Superb workmanship
• Built by a company with a fantastic reputation
• Excellent ground clearance
• Flows well
• Metal catalyst catalytic converters
• Competitively priced considering the system includes a catted y-pipe

Things I do not like about the system.

• It is only flows “well”. The individual cats are flow rated @ ~400cfm.

I decided against the system because I wanted a better flowing exhaust. According to my calculations, this system can support ~360hp loss free. How much it would hold back a car putting down more is not clear (to me).

ETA
I am not knocking this system. I think it is a really nice system, and would rock on an otherwise stock f-body, and probably even on modded ones.

Check my sig I'm putting down 445rw through a slipping stock clutch. And Dynatech does make cat deletes for this system sold through Thunder racing.

Dynatech high flow cats Part#329-79-400300 3" in/out-Jegs. I've had my Supermaxx for 3 years. Fits like a glove. Doesn't rattle. Hasn't rusted and the cars not garage kept. Y-Pipe is 3" not 2 1/2 as stated earlier or my 3" cutout would fall off. If your cars on a rack getting the oil changed the header system will sell itself. Because thoses people who buy thoses Brand-X headers and can't get their oil plugs out without burning their fingers and can't pull out on the road without scraping the asphalt see how yours fit and they want one.
System can be had for $1200 if you look around. Alot of Sponcers won't be undersold and some of them offer free shipping and in alot of other states you don't have to pay sales tax. So if you shop around?
