J-Pipe?
#6
The J-Pipe was the first mod I did on my car. I had it on for over 3 months before doing any other mods. It BARELY increased the sound at all, mainly because the cats, resonators and mufflers all still did their thing. It was only after I put on a third-cat delete pipe did the sound become more distinguishable, but not to the point of annoyance. It even took my wife a week or so riding in it to ask if I had done something else to the exhaust after that test-pipe was added, haha.
It will give you a gain in HP (although I can't give you an official number, 10whp might not be a stretch) and it increased my highway gas mileage by at least 1.5mpg due to the increase exhaust scavenging ability and better flow characteristics.

How come after u install the j pipe. You can't just bypass the third cat run straight pipe to mufflers? Why spend the money on a test pipe or HFCB?

In either case, it's just easy (and probably costs about the same) to buy a fitted test pipe with the flanges already on it.
No it wouldn't. It'd be the same as J-Pipe plus test pipe.
