Ive read a bunch of other posts on this, but never really found what i was looking for. Ive got 3 questions. 1. Do both y-pipes put out same power? 2. Are there any fitment problems anymore. 3. Do either make the bees in a can sound? I was interested in the SS TIG Warpspeed pipe.

 

Save yourself a lot of cash and just get the WSP non-mandrel y-pipe. On the same dyno and same car, the WSP non-mandrel bent y-pipe made a whopping 1hp less than the WSP mandrel bent y-pipe. I've got the non-mandrel bent y-pipe and it made quite a bit more power than the Stillen mandrel bent y-pipe it replaced. And don't fear using alumnized tubing either. Go to my homepage and look at the pic of the underside of my car. There you'll see my WSP alumnized pipe that's been thru two salty Kansas City winters. There isn't a spot of rust anywhere.

another thing with the aluminized steel one is that it comes with a 4 year warranty !
