    I would weld it or go the full route and cut the collector off and weld on a reducer to the header and run your exhaust pipe from there. NO LEAKY...

    a collector has the three bolt hole flange that clamps the two halves together. a reducer is just a pipe that on one side would fit over the end of your header and the other end would fit inside or outside your exhaust tubing. You weld it on in place of the collector so that you don't have to mess around with the poor design of the three bolt flange and leaks.

    oh i c...and then you would slide the exhaust pipe over the reducer..and what, clamp it on? or weld that to? the reaso ni ask is im making my own system using bendable pipe..not flex pipe..but the pipe with the crinkles in it so you can bend it..yea its not the best thing in the world..but its the best sollution ive come up with so far and it would do the job.

    I wonder why the manafacturers wouldn't put more bolts on their collector flanges?

    either way clamp or weld. I have used some flex tubing before and it actually lasted quite a while and when you compare the cost and life of that to say a professionally built exhaust system its not a bad deal. You just have to be prepared to change it out more often.

    yea..i was going to use the stock pipes for a 73 or 74 chevy pickup that came with duals..but not after i found out it was 80 bucks for each side (160 bucks for the pipes all together)..got the same quote from every store..so i said screw that and got this idea.

    3 bolts and 3 bolt holes is cheaper than four.
