So my high flow cats are blown, they were magnaflows that I had put on there, and I'm wondering if I should just get OEM cats put back on, or try to run high flows again, or just get test pipes. I have HKS Hi Power Ti mufflers and I'm getting headers soon, and my future plans are to go vortech SC. Suggestions?

Also has anyone else had this problem with their cats and how was it fixed?

Thanks.

 

bump, id realy like some input

 

please?

 

What do you mean by blown? Did they crack? If you're going F/I, and having complete aftermarket exhaust, why would you go back to the stock cats?

I would get some test pipes, and I'm sure the gains with the full exhaust setup will make you glad you ditched the stock cats. I would def. get resonated pipes though. I'm about to take the plunge on Labree's. It's been a tough choice ($395 is STEEP for some two pipes with flanges welded to them), but I've read nothing but GOOD reviews about them. Also, don't make the mistake I did by getting crappy test pipes or HFCs if you decide to go that route again.

Stock exhaust sucks

 

They didn't crack, they just rattle on the inside and are blue on the outside. Its the rattling that makes me sure they are blown. I think instead I am getting some offroad racing resonators with O2 bungs in them, and making my own sort of resonated test pipes. I would go legit except the shop that installed my old cats cut off the connecting peices along with the old cats, so it wouldnt be a bolt on, actually I dont even think I'd be able to get them on. The resonators should take care of the rasp and give me a place to stick my O2 sensor.

 

now i just have to figure out wtf im going to do about emissions...
