The biggest mistake I made when I joined this sight looking for mods is not listening to most of the people about the DG pipe. I figured I could save money and put it somewhere else so I bought the DG pipe and It was the biggest piece of ****. It actually lost power even with rejetting. DG claims a 5 percent gain. WHOOHOO!!! 5 percent of 22 hp is like what a gain of 1.1hp. Well on Dyno tests they say the DG pipe lost 3hp. Yah the pipe looks great but not worth it. An HPD or RCR pipe will give you a gain of 8hp. That is like a 65 percent gain. I not only lost hp and money with the DG pipe but I had to go and buy a good quality HPD pipe. It has benn the best $260 I spent. Now the DG pipe hangs on the garage wall. I would not even sell it to my worst enemy. It is not even worth the dust that it is collecting on my wall. HPD or RCR all the way!!!

 

Hey, Aaen is a good pipe too. I think Bubba is running one now also and I believe he has tried many different ones.

 

Sorry I forgot about AAEN. I have never had an experience with AAEN products but beople that have seems to like it very much. The only thing is that the dyno for the 250's using AAEN pipes is not as high as HPD. They are like 1-2 hp less.

 

Yes that is true with the 400 also. The HPD pipes run at a slightly higher RPM thus a 2-3 MPH top-end difference and a couple more ponies on the dyno. I would have probably went with the HPD also but I was modding on a budget and the Aaen stuff was slightly cheaper.. I have still spent approx. $1500 with them, but It was all worth it.
