After installing BBK LT's and an O/R H-Pipe I've got this small problem...

Alright. I recently had BBK LT's and an O/R H-Pipe put on my car to replace the stock manifolds and vrs o/r x-pipe. But I kept the Maganflow catback. Now...when I'm driving I hear a hissing sound. Kinda like a leak. It gets louder the more I step on the gas, and its annoying as hell. I am like 99.9% sure its not a leak. This noise comes from underneath the car (not a header leak thank god!) I was told I'd hear some crazy noises with the addition of longtubes, but I never imagined they would do this Seems to be in the same location as the mufflers. Perhaps before with an x-pipe with a straight through muffler...it didn't do it. But now with a h-pipe I need chambered mufflers?

Is this true? If so, can you recommend a comparable muffler in noise to my magnaflows and that would sound good and fit well with the rest of the magnaflow catback?

Thanks a lot. I really appreciate it.
