ATS Tri-Y headers

[ss dave]

A thanks goes to Tyler At ATS for his help. Replaced my Hooker, Super Comp conversion headers 1 3/4" with the ATS ss 1 7/8" Tri-Ys, 3" exhaust all the way to Flowmaster Delta 50's, added DMH cutouts for fun.

Initially one tube didn't fit at the steering box- common problem. Sent them back to ATS, they reworked them and returned them within the same week!
Got a 69 Camaro vert with an LME built LS7. We massaged the headers only slightly to get around the box. Re-tuned the car with the new exhaust and new MW alum. driveshaft.

Goal was 500whp. The tuner stated the engine was very temp sensitive and the dyno shop was 100 degress at 50% humidity. On the Dyno Dynamics dyno got 502whp! Even better the TQ curve flattened out and increased from 3500-7000. Can't wait to pavement test it tomorrow!

Thanks Tyler.
