I was going to make a custom set of headers, trying this set up for now and still have to dyno to make sure it does actually go better than the 20v headers and doesnt loose too much down low.
You are so right. I got a SSAC header and I think the stock 20ve header is better (I have the complete stock header with primary on secondary, only thing is that i had 2" collector) and a 2.36" (60mm) catback.
I am going to take it off the SSAC and put on back stock.
I find the stock has longer primaries and secondaries. Also has larger diameter secondaries. Only thing is that SSAC has larger diameter primaries and larger collector.
I am going to get a 2.25" or 2.5" collector.
