Are the Y pipes that redlinemax.com makes any good?and also did any body change their catalytic converter?

 

All y pipes are pretty much the same as far as performance. Some are a little quieter than others like cattman. Haven't heard any problems with redline though. Many people have changed there cats to high flow or test pipes. There is very little to no gain in changing your stock cat unless your running a turbo or supercharger.

 

Just try to find the cheapest that has all the qualities your looking for in a pipe.

 

You shouldn't change your catalytic converter unless it's defective.

 

Last time I heard, the y-pipes made at redline were the same exact design as the ones made by WSP. This was declared on a thread here a month or so ago, by a few 'official' people, I suppose, like redline's official spokes person. I have a Warpseed on my Max and I love it so. The only problems I've been hearing about redline is it's delays in shipping.
