i am running on 1600cc NA with BOT. my exhaust setup is 2.5" downpipe + mid box +2" straight pipe + straight flow muffle. Due to tak boleh tahan with the loud exhaust, i added another mid box.
I just bought myself one HKS IV Type 1 TT. Any sifus out there who has any guidance on how to DIY install or hardwire the TT on BMW E36? Diagram ka? Wiring plan ka?
