Dynatech x pipe cat delete pipes?

[justablur91]

so im running a 3" dynatech high flow catted x pipe on my 2007 and i want to remove the cats, does dynatech make off road intermediate pipes to go in place of the cats? i could have swore seeing them awhile back now i cant seem to find them anywhere? other option is just to gut the dynatech cats.

VMP sells adapters that you cut your existing mid pipe after the cats.
Maybe that's what your thinking.

no im actually looking for the 2 pieces that come on the dynatech offroad x that connect to the collector, essentially converting my catted x to a offroad x

Yes, They sell the sections to replace your cats. I think I paid $129 for them in the 3". Summit use to carry them also.

[08 vap]

I'll see if I can find it.

Here's the part # I ordered. The picture is not the correct picture. It's two pieces of pipe that takes the place of the cats with two flanges to bolt to the header.

awesome and what year is your car? so basically you just pull the cats off and replace with these pipes ?

Mines a 08. Running the Dynotech headers with 3" X-pipe. I was running the Dynotech Cats but with just over 700 RWHP they started melting in the center so I removed them. the kit I posted will have the pipe, flanges and gaskets. Just unbolt your cats and replace them with these pieces.
What mufflers are you running? I'm running the magnaflow 3" and without the cats it's loud.

yeah i just did a tvs swap 680-700rwhp and my tuner suggested removing cats i dont want them to fail, im running corsa sport muffles and honestly its rediculously loud with the cats on it now im gunna have to find a different muffler

I just gutted mine out, it was a lil bit harder than I thought since your knocking metal out. But can be done. Mine was a lil louder not to much worse.

 

[justablur91]

^ so you gutted you dynatech cats out? that was another option that way the car still appears to have cats on it.

 

[Nsssane1]

Yes gutted them. Takes something like a jack handle something sturdy and keep pounding. And some type pry bar. That's what I used. Some type of press would be better but didn't have that. Comes out smooth like nothing was ever there.

How would describe how the sound changed after gutting your cats? I want to gut my stock H but I've head that it creates a "echoing" sound because of the bigger walls of a hallow cat instead of the same diameter cat delta pipe.

Well on my setup mine sounds pretty close to the same as with the cats only a touch louder. So I was glad I did it. But probably different with other exhaust setups. But no I don't notice any type of echoing.
