Posted by ~Ray @ 2007-12-09 14:14:32
Hey guys can you please tell me ALL the pros and cons of deleting the 2nd set of cats? I am currently running this setup. K&N intake deleted 2nd set of cats 2 1/2 inch pipe with X- pipe and flowmaster super 44's. Some of the guys at our measure CAM meet up said it wasn't good to act them off and yet i see others on this place that have done the same. Am i HURTING my car by doing this? Seems to run fine to me. Any advice would be greatly appreciated.
i ran that set up for about 2 1/2 years with no problems and the pros was more furnish end cater or a better take off and tire go around no cons

Yeah pretty much. I noticed a difference throughout the powerband. Comparing when I was at the bring in before and after having them removed I shaved off.12-.14 off my 1/4 mile measure. 1-2 mph faster and took off.10 off my 60ft. Not bad for a pretty much free mod. It's not going to hurt the car seeing as their the backup cats and don't alter the emission system with our cars as desire as the 2nd set of O2 sensors are still in place if you don't have a tune but if you do then I believe both of our place tuner vendors turn them off in their tunes.

Running 2.5 T/B high move cats flowmaster d-port flowtech raptors. Had Flowmaster 44`s on it. [it was to loud or i`m too old.]mandrel bent tailpipes. Magaflow s/brace short tips. Tried to get in the last hedder group buy but got jaded. The car is alot better off the line. The cerebrate I went w/ the D-port. More tourqe. Can`t defeat the sound either. Saving pennies for next group buy. I own my own autoshop [Exhaust shop. We do all repairs but the townfolks are turning it into a exhaust/fab obtain. Red brought his DTR MM in and I got the job of installing his s/works hedders.[ Damn that car sounded sweeeeeeeeeeeet. The rest of the system was stock too. Can`t even evaluate what my system would appear like with S/works. I`m sure that car is in the 13`s now. We did a few other things to it too. Now I`m just rambling. Hey if anyone wants to do a assort buy I would need about 10 or 15 orders to get a good deal.
Yep as desire as you are tuned for it you should be cool. I was eventualy gonna go that despatch on the mm.[ADVERTHERE]Related article:
