apparently their intake doesnt really work, i was interested in it and email them about it. "Hi Mike, the intake was developed so the "Performance Option" boost tubing can be used. I have not brought the intake to market yet as there has been very little interest. The stock boost tubing can work fine. let me know everything you are interested in.

Thanks." this is what they sent back, personally i have the hahn 3" catless DP with electric cutout and wouldnt have it any other way, i did pay a little extra but you really see the quality, you do get what you pay for, their customer service was really memorable to me, no problems and nice as can be, im planning on purchasing their hot side piping in the next couple of weeks. so my verdict is, id go with hahn

 

What differences are there between those 3 pipes?

 

I love my Bad-Mab, but I have a 5 Speed so I don't know about fit.

 

$300 for a DP is just way too much in my opinion. I have known Dan for a long time, he used to be a HUGE 94-96 Impala SS vendor, selling the best of the best. I guess it is the same way with our cars, but for $300 I can get a full, custom bent 3" catback.
