Whistle while you,,,, drive?

Trailbeast, did you find a cure for your Duster whistling? Also had a question about exhaust manifold stud/bolt kit, wow, they are kinda salty but about to buy a set. You recon I could just get a good grade 8 match up at the local bolt and screw supply company downtown? What you use?

Someone just PM'd me with that same question about the carb.
I just gave up on it for now due to the fact that it doesn't make it idle or run any different and because a friend is giving me a 750 which I wanted to change to anyway.

Yea I'm positive you can get bolts or studs a lot cheaper without any difference in function.
Just keep in mind you are going to have to get to whatever head is on them when a header tube turns right over the top of them.
I got a set of 3/8 12 point stainless header bolts from Summit and they are fine.
Don't even think you need grade 8.
5 would be fine.
