Just finished my 540 ci nat asper motors, i own etop light headers(less than 6 months old) which are on the motors now and in the boat, I'm wondering if I'm losing hp and how much hp buy using these headers, the motors fit the parameters of cmi's big sport tubes, wondering if i should spend the money.

You are probably losing hundreds od horse power,you should sell me the e-tops really really cheap and buy the big tubes for yourself.

I had the same questions when I was doing my 540s this year. I kept my e-tops - too much $ difference with questionable increases?

I tried.

well it seems like there is not much difference, dyno numbers are 656hp at 5350, but big tube headers were used on the dyno not mine.

nortic as for selling you them really really cheap not a chance yet, you never know, depends with my next endevor is.

a 36 deep impact is high on my list right now, w/ trip 300's
