Well i also got there presilencer and y-pipe. All i gotta say is omg. It is so loud even with the presilencers in my mufflers. Its just like my straight pipes before. But man does it look good, u can even see the big chrome when im driving from behind. And it is faster, i only noticed a difference past 5k, but then it takes off. It also burns alot more rubber going into 2nd gear, a good long screech. Installation was easy, bolted up real nice. But man it sounds intimidating at idle. It turns heads for a block radius @ WOT. :o

Ya I have a simular setup with a RB Header, PreSilencers into a Turbo Muffler (DynoFlow) and it was WAY too loud... Sounded cool though. I added another cheap turbo muffler at the rear of the car and that brought the noise down. It's all 2-1/2" and I may have lost some low end power... put it sure pulls hard.

I put the RB header and presilencer on my friend's car. He has a RP cat-back, which gives it a high pitched tone. With a Racing Beat cat back it should have a lower, quieter tone.

yeah it has a lower deeper tone, i like it but now im in a $600 dept to my dad, which i don;t like.
