the PRT system is really quite revolutionary as its killing drone, while not interfering with flow at all.. or the overall sound quality... Its just a better concept then a muffler for great sound... headers def. increase drone.. adding sound deadening on the xpipe is the best way to do this

the PRT doesnt go through any type of muffler.. It covers the middle portion of the x pipe.. looks like a muffler, but is actually filled with sound deadening against the pipes to kill drone. It doesnt limit sound, but its more of a noise cancellation system for in cabin resonance.. no one has tried it with headers yet, so I should have more feedback on the effectivness shortly.

Are you saying that it's solid piping through that housing, WITH insulation around solid pipe??? The pipe isn't perforated? That doesn't make sense. Can you take a pic please of the inside looking through? Or can someone comment further?

i am sure it is a straight through muffler / h-pipe....no turns with at least same size cross section = no lost in hp w reduction in noise.

It shouldnt really make sense from past experience considering there is nothing else like it on the market (except knock offs)
Im not sure if the PRT is an h pipe or an x pipe though.

Chasehunt.......How was the install? Did everything line up? Did you have a re-tune done? Any problems with the CEL?
B&B lists three x-pipes: with cats, no cats & resonators. Which x-pipe did you install?

glad we found someone else who has some actual experience with these headers. I have my friend bringing his new digital rebel over as soon as I get my package from tbyrne.
Im believe the PRT retains that off throttle crackel due to it still being an h pipe style...this is going to sound good!

I have the Bullet PRT with stock headers. The Bullet without the PRT is LOUD. With the PRT the idle is much louder than stock and has a deep rumble. AT WOT it is very reasonable somewhat like Route 66 but nowhere near as loud as straight Bullet. Still has some drone but tolerable. I would like the hp gain from headers but theres no place to put the cats with PRT and I'm worried about odor and increased drone.

what do you think will be louder straight bullets with everything else stock.. or headers with no cats prt and bullets lol..I do think the regular bullets are loud enough for my tastes.. the loudest part is the popping.. less popping and more actual sound is needed.
I was updated on shipping and the headers will arrive on the 20th. Someone will be coming over to take some killer photos next weekend.

im begging to question the real neccesity of headers wouldnt l92 heads l76 intake combo make more real power? the z06 has similar headers with cats and makes plenty of power without LT s

Actually a heads/cam engine needs long tube headers even worse than a stocker does.

So, you are going to put a header on your car that the manufacturer admits only picks up 22 hp max in order to save a few dollars? Buy the AMR (I am assuming you don't want to pay $1800 for the best, LG's), they are only $1600 and you may be able to save on the tune. Plus, your car will sound and smell better with Cats. You like the sound without cats, however, it reminds me of the sound of a garbage truck, way too much rasp. I just don't think you'll be happy with the B&B's. If you are determined not to run cats, then get the Kooks or AMR's without Cats, they are not that much more than the B&B's and they'll make more power.
Good Luck,
Glenn

I don't know that I would fool with the B&B headers. To many other "better" options out there for about the same money, maybe a dollar two more, plus you get cats and more power.
