The new CMI E-TOP 454/502 is a direct replacement for your GIL exhaust. Comes in Satin or Polished. We are a direct distributor of CMI, call us for your OSO member discount. 847-623-2737.
He has GIL manifolds now and wants an upgrade. I assume that would be Stainless Headers not just another manifold. Go with the CMI's and bling your boat as well as performance.
My motor guy said I'm probably loosing 30-40hp with the gills over headers. If I score a pair I'll have some gills that were used 1 1/2 seasons in fresh water probably 30-40 hours. Tails are dry and are way to loud....ok sometimes
The SM HT III or even II will not lose anything on a 502 compared to SS headers.
Only diffr. is the torque on the headers may be a little more on the top.
The motors are 540's with baby blowers only 3-4lbs of boost. They made 725hp @ 5000 rpm with large tube headers. We may run them on the dyno with the gills and see if it drops. I can only get the boat to run 80 @ 5000 rpms with 30p bravo's
I have 2 sets of cmi e tops/bravo that I am taking off my tiger in a couple months. I will test them and polish them. if you are interested pm me. i have never had an issue with them and its just time for a new set. it is being winterized now, if you need them sooner I might be able to swing something.
DOUG sounds like Offshore Rob has what your lookin for ,or if you need Leon @ dereberrys cell # let me know and get her done .talk to ya soon :cheers2:
I have 2 pair of CMI 2 piece tube tops with tails, they only have 20 hrs on them and they are in excellent shape. Give me a call, I can give a super deal on these.
