Running KWSC HB SC with stock exhaust. Looking at Megan headers and 60mm Skunk2 catback system. I'm sure this will require a retune. Would a a cat delete be necessary to relieve a choke point? I am afraid of it being too loud. I was looking at the megan down pipe if it would add and performance. Any suggestions?

Thanks!

 

If memory serves me right, you were supposed to be running a test pipe in conjunction with KWSC high boost kit as the Hondata Flash Pro tune that was supplied with the kit was mapped for use without a factory cat. Again, this is just going by memory. There are a few high boost owners lingering around here on the forum, hopefully one of them will chime in.

If you are concerned about tuning whether or not you change your exhaust set up with your high boost kit, Hondata does have Flash Pro for the GD3 and it does include the KWSC high boost reflash as a base map.

 

Thanks! I am using a Flash Pro. I have heard the megan test pipe with resonator would help with volume.
