exhausts for 496 engines ?
 
cmi has a system for the 496 engines claiming 50+ hp for $3600, is there any other exhaust systems putting out same hp for less money ?

CMI is the only company that has released dyno sheets to date. ;)

Yup,, if the tubolaters alone are worth approx. 15 hp and the cmi's make 50 ,that makes the cmi's about worth 35 hp... 4 K for 35 HP is quite expensive and 7-8K for 70 hp is VERY expensive. If the headers were reasonabley priced in the 2K range I might consider it, but not for 3,800..

I agree, the price on these are not justifiable for 35 hp. :rolleyes: Hey, they woud sure look nice though... :D

Chris...you've been grumbling since the introduction of the CMI headers. :rolleyes: :D

The price point you're suggesting just isn't going to happen in a stainless steel tubular header.

We've sold more than 50 sets of CMI 496 headers in the short time since introduction. Every single customer that I'm aware of has been a satisfied customer.

If you don't want to pay the price of admission, I understand. Go whatever route makes you happy.

For those who do want the benefits of CMI headers, we have dyno sheets, real world performance numbers and phone numbers of customers to back up the claims ;)

Fred, I know i'm grumbling,, I want them but just can't see spending 4K for 35 hp.. and yes they would look and sound killer on my motor.. :D

Not only that, before you deleted your post w/ the dyno sheet I thought I remembered seeing only 42 hp ?? so that makes them worth about 27 hp which makes the 4K even more unjustifiable for 2 possibly 3 mph..

Actually that is CHEAP for the amount of speed & HP gained.
Best bang for the buck that I am aware of.

Na, how about starting with the props first.

The best gain that I've ever heard about from adding the 496 CMI's is 3 mph... :rolleyes:

That can be accomplished with a little prop work at a fraction of the price.

I have been wanting the CMI's also. The problem is they are not compatible with the Corsa Quick and Quiet Plus. I would spend the money if it were a direct bolt on. Now I have to change the complete exhaust system which adds additional $$$$
