Flowmaster made there name in chamberd mufflers because the flowed better than most other camberd mufflers out there and sounded great on a mustang. And we all know how many mustangs there are out there. On a Turbocharged engine a high flowing muffler is key to making power. Thats why you see dump pipes on alot of weekend racer rides. The muffler that RPM uses is from Magnaflow its better because its a straight threw design. NO CHAMBERS. Its also stainless steel so it will still be thare even after the truck rots around it.SteveD said:why?
James Thomas said:Karl, I understand what your saying and in your case of being (I think) a pretty stock truck, it won't make that much difference and I do admit that they sound good. Buuuut, the above posts are not only correct but a little light. I have actually seen chambered mufflers (not just Flowmasters) actually do damage to some of our high HP trucks and a few Gn's.
I think they were just warning you that if your looking for sound then ok, not max performance. If you put a back pressure guage in your exhaust and swapped from a Flow to ???, there is a big difference and this is dyno proven, not myth.
