If you are racing cars it's very important. For our purposes, this doesn't seem to make a big difference. I had a 1.75" headers into 2" collector which worked pretty well and sounded like music with a cherry bomb glasspack (for about 5 hours). I use a 1.75 to 2.25 on the 20B.
On the Renesis it is almost literally a non factor due to the lack of any I/E overlap.

I need to order in a Merge Collector for my exhaust system and I was wondering what some of you are doing in this dept. Can I get a way with two 2" into one 2" collector or does it need to be 2.5" or 3" on the way to the muffler? Also, is burns he only good source for this? Their price seems pretty steep for a two into on collector in 304/.065 SS.
Thanks for any inputs.
