Are two cut-outs overkill????? I'm getting a new exhaust built.
3" pipes off each collector, than into two 3" cut-outs, than into a Flowmaster merge (3" INLETS, single 4" OUTLET), than back to my MagnaFlow.
Or should I just have one 4" cut-out after the Flowmaster merge?
Thanks.

I will have no cats. I was thinking of putting them right after the collectors. I don't have o2 sims, should I get them?
What is the difference in power gains from dual cut-outs or just one 4" cut-out after the merge? Might just be easier to do a single.
Also, I'll only have these open when I run someone, I'll never just drive around with them open.

NO....mine are DMH's which have slightly bulkier motor housings. SOB's are heavy, and in hindsight, should have elected to go w/QTP's.
Don't get me wrong, I love the DMH's but for tight clearance issues, I would have been better off w/QTP's
