It is, but higher flow ones are readily available. I'll see what I can dig up for ya. I'm planning on trashing mine anyway and going to true duals, so I won't have to worry about it.

 

I looked a while back and only found ones for 2wd.

 

Is there a difference?

 

yes, front drive shaft. GS Motorsport has them for 2x4's but not 4x4's. they were looking for a volunteer truck to build one but no one down in the LA area has a 4x4 who was willing to volunteer. I'da done it if I was down there!!!

 

Huh, kinda surprises me they made 2 different parts. The 4wd version should fit fine on a 2wd, it's basically identical underneath in that area, except the 4wd has a driveshaft. So why not make them all the same? Makes no sense to me. But I've said that a lot about Dodge since buying one... [:@]

 

will a high flow cat reduce low end torque? because the mid pipe fell off (cat to muffler) a few months ago (wasn't clamped tight enough) and i noticed a huge drop in bottom end. came right back after i welded the bastard back on there. why does backpressure effect low end performance?
