power gains with cat bypass pipes
Found a set of cat bypass pipes on the local ebay for a very reasonable price.
They will be a part of my project to get rid of the 3k rpm vibrations among else.
Also some weight reduction is a good excuse to by these.
But has anyone noticed any powergains with these?, exhaust sound?
In the manual Us 2,7( my2000) engines has 217 hp and Row has 220hp. From what I know the only difference between the engines is the extra set of catalysators so I guess that I will at least have 3 more hp after the mod
BTW,The seller claims 25 hp increase.......
