How much louder will Borla Headers make my car?

[99 R/T 10]

BAKNBLK95RT,
Your doing almost the same exact mods I will be doing in about a month. Borla headers, Alum flywheel. How did the HP feel after the mufflers and high flow cats? Did you go with 3" pipe or stay with 2.5? I'm sorry I can't really help out with your question, but just think of the neighbors you get to "impress".

I put on the 3" belanger exhaust, high flow cats, filters, and smooth tubes not too long ago. I tried to do a before and after comparison with a g-tech to see how much power I really gained but I had a problem getting traction at anything near a sane speed. It certainly seems like the car has more power than it did before but I don't have any numbers to back it up. What I can tell you is that the car really seems to like the high RPMs a lot more than it did before. It seemed like before the upgrades the car would just run out of breath towards it's redline, as opposed to now where the car keeps pulling all the way through it's rpm range. I would definitly like to hear people's experiences with headers (power and sound). I am very tempted to do those next.

I've got alot of posts on this subject! I've got Roe Racing's $3100 package and it's awesome! Look in the media section on this board for my posts. Sean Roe pulled them up at one time. I'm at 405RWHP and 498RWTorque. Raced a 00 R/T 10 and pulled him. Sound is awesome.
