SL/R230: SL500 Headers question
I have an R170 6-speed with an SL500 swapped in. I was wondering if anyone has headers and what gains were made?
My welder and I are thinking about designing a set for my car but I am getting mixed opinions from people on whether the cost to build them is worth the gains, or lack there of.
Anyone have anything to share? Dyno sheets maybe? non-tuned vs tuned?
Anything would help.
Thanks,
Josh
