On second thought.

If you want to shave some weight for cheap money...which I still think it’s a waste of money. Go with optima batteries.

Atleast you won’t waste $10k realizing it was a bad idea. HAHA

I put IMCO Thumpr's on my 292 with 377 Scorpions in it, shed weight, had better performance out of the hole, gained zero speed. I had labbed 30p Bravos and the best I ever say was 78.2, GPS confirmed. The exhaust did make it sound way better though.
