Turblow

Hey guys

Ive got a turbo d16, currently running open downpipe, emissions time is coming up and I need to go so im making an exhaust from scratch.

Currently I have pretty much all of my exhaust made of 2" pipe with some flew sections and a cherry bomb turbo oem style muffler and a cherry bomb resonator (both were close to free)

Now I need a catalytic conveter

Im going to have a 3" electric cutout exhaust and that will be closed at the time of the test but I need a cat, I was planning on getting an oem, but I thought that might be a huge power loss when driving around with the cutout closed.

Should I go with an oem catco replacment or should i go ahead and can a cheap high flow one off of ebay?

Will a used cat work ok?

Thanks for any info

glad I dont have to worry about emissions , though I believe a highflow cat will pass inspection. It still has the catylist and it still purifys the exhaust, so why wouldnt it pass

spazz0nater

no, they probly wont pass, they look like a cat ont he out side but are packed just like a muffler. no honycomb design on the inside

Depends what one you have. A magnaflow or Catco have the catalyst in there. Ebay test pipe cats are just that....pipes

get a magnaflow. I got a 3" one from summit for 60 bucks

what he said or get this http://store.racing-solutions.org/cahifl2caco.html 50 bucks, if you go the ebay route make sure your not buying a test pipe 50% of the "high flow cats" on egay are testpipes and dont do shitt for emmisions search for carsound converters but i think this link is cheaper

yeah get a carsound or catco, I think they're the same. Also magnaflow is good, that's what I got and it has the honeycomb and catalyst.

you dont need a real cat for emissions
all you need is your "Emissions Tune" chip
