Hi-Flow Cat?
Im trying to decide which 3" Hi-Flow cat is the best out there and my search didnt come up with the results I wanted. Im looking for something that will last at least two years, fully bolt on with air pump tube already welded on, and I can recive within three weeks. Im also running a pfc which I have read causes the air pump to work differently lowering the life span on a cat.
I was really interested in the smb cats but they are all the way in Aus so I dont think they can get the cat to me in three weeks. Im gonna shot em an email and see what they have to say though.
Thanks guys,
Chris

We have had all three.
The Pettit CAT plates broke off and failed within 6 months. Replaced it with a pettit and it happened again.
Random Tech CAT clogged in one year.
The Bonez CAT has been on for 2 years now and no problem.

Another vote for Bonez. Mine has been on for more than three years with no problems. Meets all your criteria and with quality material and contruction.

Is there a variable missing?
For example, a person drives his 7 2000 miles a year and his hi-flo cat is still intact and working without a problem after 4 years. Same hi-flo and another person drives his 7 daily and racks up 20,000 miles a year and has 2 years on his with no problem.
Years of use seems a bit ambiguous. Id be interested to see what kind of typical use (freeway, around town, racing , etc), how many miles driven, and how many years one could expect from the cat.

Banned. I got OWNED!!!
yeah my boy has had the Bonez on his for like two years no problem. Sounds like you can't lose with the Bonez. Food for thought, what about a metallic substrate cat vs. high flow. better or not as good?

I was also wondering how the metallic substrates had been holding up with use on the fd as well as any emissions issues to consider. Another met. sub. feature which was unclear dealt with the cell density of the substrate and the effects on performance, heat retention, and emissions standard minimum requirements.
I followed a couple of differerent met. sub. threads and didnt feel that there was an abundance of conclusive data. It does seem to be the way to go if it can withstand the tests of time while being subjected to the fds hot exhaust, considering its light weight, small size, and higher flow characteristics as compared to a hi-flow cat.
