I want to put a sweet exhaust kit on my 68 coupe thats sporting a 289. Edelbrock performer 600cfm carb and matching manifold. A good street car with low end torque with decent quarter times. Also wondering about cut-outs with mechanical valve operation or should I stick with electric?
ive seen the electric cut outs and wonder on the life span of the motor since it a basic window motor and its near constant heat.What kind of "decent " quarter mile times are you looking for?
Some of the more expensive cutouts actually have something like a servo motor that lets you open the butterfly however much you want. I too wonder how long they last, though. Another issue is if they leak or not. I personally would just get the manual ones with wingnuts and a plate.
I have the wing nuts and plate one, they DONT leak, but i got a ticket one night becasue they were open (had i had electric it woulda been different) lol
I saw some "manual" cut outs a while back that had a brass on metal slide that would be moved with a small bar,they looked pretty good,but i havent seen them since.Or check JC Whitney,they might have cable actuated ones.
I was looking at 14's for the quarter.
Yeah, I saw the manual cut outs too at Summit racing made by mr. gasket. Being that they were $40 each, I think thats what I'm looking at. Im leaning towards getting a 2.5" flowmaster kit. I have stock exhaust on now so anything will be better.
So in short. I want loud pipes that will aid in getting 14's. Cut offs would be nice too. Hey thanks for everyones responces. Its very much appreciated.
Headers with a a y shaped collector tip. One side typically goes the mufflers and main exhaust the other one has a "cutout" that you can open the headers with.
One of my friends has electric cutouts on his 68 mustang, I was just asking about them since I was thinking about doing them on my 67, he told me they don't leak and they still work as good as the day he got em almost a year ago. Not to mention its a damn cool option.
