I have an 03 max with Injen CAI, Warpspeed 2.25 bpipe and HP racing muffler. I have a slight drone in the lower RPM ranges which is bearable, but I am considereing putting in the warpspeed y-pipe and I was wondering if anyone has done this and noticed any difference in sound?

 

The drone I had with the Powertech muffler and a stock Y-Pipe was more than what I have now with the Cattman Y-Pipe and Powertech. I would recommend the cattman over the warpspeed Y.

 

its more money, but after hearing all the complaints on the warpspeed, cattman all the way!

 

You really want the hotshot headers.

Call quick for an org discount. $599 regular price. You aren't going to gain much with a Y-Pipe only because you still retain the precats.

 

These are on my Xmas list. Hoping these are the real deal hp wise.

 

The stealin ones are 20HP and I believe the Hotshot are superior in design because they are equal length and have longer runners.

I ordered a set yesterday along with a set of Illuminas.
