well that depends really on what our stock cats are made of? are they ceramic cores?

ceramic or not i wouldnt want a cat to explode and kill my turbo...

agreed, but a good hfc shouldnt have that prob. stock may

I would think the pieces would have to be quite large to cause damage, I trust what STS tells me so I'm not gonna worry about it

Just telling you "not a problem" is realistically being lazy and not wanting to tell you the pro's and con's of what to expect.

I would suggest you get a second opinion from another reputable company such as GTM since you wouldn't believe the words from a fellow member.

Plus, any small material flying through the blades of the turbo isn't exactly something you want.

think bird thru jet engine..... :ughdance:

So a test pipe would be the best way to go with a sts system? Might be a problem for those who live in "carb testing " areas . Anybody have to take there system off to pass a emissions ?

carb testing with turbo/sc isnt likely going to pass unless you have a stillen 50card legal system.

I asked STs and Andrew and uam ( who I would of bought the test pipes from ) even he said no even tho he coulda made money off me . That's 2 sources telling me it's fine, I hate the sound of test pipes and want cats. And I'm pretty sure towers runs cats correct me if I'm wrong towers

get ART pipes and problem solved...

i thought no matter what, "some" material does burn/break off the HFC's core. it might not be much but some does come off......no?

Why would you ask GTM about a product that is not there's? Of course there are going to have there input in there about a competitors kit.
Have a questions call Vernon or Rick at STS. This setup is different compared to other kits.

I'm running with the stock...no changes there. At the same I'm looking at tearing the system out. It's not that I don't like it, I'm just gonna buy a manual and found a low mileage 40th for a good price. Now just to get it back to stock.

part out? lol (^^^)
