GST Downpipes

Quick question as I'm looking at GST downpipes... are all of them made to delete the cat? They all look like they do. I plan on using a GST downpipe and then added a test pipe in place of the cat, then can swap out the test pip when I have to do for emissions.

So no one with a GST has an aftermarket Downpipe? Really?

:dunno:

We make our own exhausts around here... Who needs a cat anyways?

I have a DP that doesn't eliminate the cat. I got it from Extreme MotorSports, but I'm not sure if they are still around following the fire. They were supposed to be opening back up but their website is still offline.

Was it specific for "with cat"?

Dave, why don't you just get one without the cat and then cut out the section you wanna put the cat in and weld it yourself? That would be way easier than trying to find one with it. :2cents:

Yeah, they had two different pipes, one if you wanted to keep the cat, and one if you didn't.

Cool cool thanks. Not exactly cheap are they? Maybe I will just buy one and cut it then.

For future reference ladies, the GST DP WILL NOT WORK on the 420a. After much research, the GST pipe has to be to the left to get around the oil pan and the center brace, while the 420a goes the opposite way. Looks like I'll just be fabbing up my own turbo->cat exhaust now.
