So it was brought to my attention today that my true dual set up might be hurting the performance of my car. Apparently a friend of a friend had a Y pipe on his car with a one chamber dumped and switched to an X pipe true dual set up with bullets. Well they dyno'd the car and he apparently lost 30-40 hp and then at the track he ran .4 tenths slower. I personally don't believe it but I am just wondering what others have experienced or if anyone has heard of this? Was apparently due to back pressure from the baffles? Any imput would be great.

what cam was he using?

I could maybe see there being a slight difference between the two, not sure in favor of which but they would be close either way. 30-40hp LOL, only if he was running 1 3/4" pipes on the true duals.

What kind of bullets? Fiberglass packed like dynomax or chambered like sweet thunders?

I was told they were dynomax bullets. Its kinda hard for me to believe also. Some friends are telling me to switch to 1 chambers to help increase performance because of the 1 baffle in the flomaster. I love the way my car sounds.

Dynomax bullets flow straight through like an open pipe. There is zero restriction.

Sounds like your friend's friend is full of ****.

ANY backpressure is a bad thing. A setup with less backpressure isn't going to cause a loss of power. End of story.

I went from a 3 inch ORY and magnaflow catback to a 3 inch true dual setup and only gained 6whp/7wtq. I'm switching back to a ORY lol
