Did you have happend to do a pre install dyno?
That's what I would really like to see a pre and post dyno on a couple of these installs. It's a little extra $$ but then you know what your car is putting down.

A pre and post dyno wouldn't have been good on Taz's car. His pre-cats were so messed up, he lost BIG power just having them on. I can vouch that his car has gotten SO much faster with only the pre-cats, but more than likely it is due because of the OEM pre-cat was so clogged. Still, looking at the pre-cats..they were very nice(high quality) and I think they are well worth the money spent.

So we spoke about this on my6thgen.org in this thread http://my6thgen.org/showthread.php?t=2680
We came to a estimated conclusion that....
Cattman headers + y pipe gives you 25-27 whp
Racingline HF Precats + y pipe gives you 22-25 whp
W/ the racingline HF precats - you'll save probably $300-400 overall [installation & product cost] over the headers. You'll also not have to worry about gettin o2 simulators as you will not get a CEL* [as stated by racingline]
Saving $400 vs 5 whp... IMO ill go with saving $400 lol.

I installed them on my Altima and love them. When I installed them I also installed the ebay maxima exhaust. I have had them for about 3 weeks now and have no CELs. MPGs seem to have improved. Throttle response and torque have increased as well. I'm very happy with my set.
