I agree. Been running a T ram on the street for a few seasons now. All i can say is if your gonna do it for ET, use a sheet metal t ram. The cast units weight a ton. I probably added 35-40# to the car. I only ran it at the track 1 time. I was down 2mph and 2 tenths in the 1/8 and the 1/4 compared to a single 1150 Dominator. I did have a humid day when i last went with the T ram and the added weight with exhaust vs no exhaust with Dominator i'm sure it was very close to 100# added and the bad air day on top of that. Flip side is they run great on the street once properly built/tuned. Easy start up without throttling it and will idle in traffic all day and stay clean. I always say better than fuel injection. Next time out i will be sure to leave the exhaust at home and pic a good air day.
