Those following my flowmaster threads... I was going to take them off today but decided to do a little research on resonator tips... The stock four tips are full of little holes on the inside wall. These ARE indeed resonator tips. I got two four inch long reducers, drilled a lot of little holes in the small diameter, inserted them small end first into the flowmaster tips.. So now it is a double wall type tip.. The annoying drone is COMPLETLY gone. WOW! I could not believe it.. It still has the same sound ....maybe just a little quieter but by very much. I am a tinkerer and love to do things like this. It made my day when I took the car out for a drive. Incredible that the people that make set ups parts cannot come up with simple solutions.
...Thanks for all of the help and advise... I promise no more flowmaster threads.
That's great news. When I contacted Flowmaster on the phone, they told me they only produced 2 tip exhaust for the vette but were working on the 4 tip. Where did you get yours??? Do you know what model # they are?

The four tips I spoke of are on the GM mufflers.... I noticed all of the holes. I made some inserts for the single tip Flowmasters. Re read my last post.
I got two 2 1/2" - 2" reducers at Pep Boys but any parts place that carries exhaust stuff should have them.. Get the longest size which will be about four inches. Drill about twenty 3/16" holes in the small diameter and cut a slit the full length of the part. Close the diameter up a little and knock it into the tip of the flowmasters small end towards the muffler. They will go in kinda tight so they won't come back out unless you want to take them out. Leave a little bit so you can get them out if you want to.

Well I'm still pleased with the way my Flowmaster system sounds BUT I'm very curious to see photos of what you did. Do you think your inserts will stay in place with the heating and cooling of the exhaust system over time? Sounds like it would be pretty easy to the get a 'tack weld' to insure that the inserts won't come out.
So you now have a separate tip made from thin steel, inside the regular tip? Got an pictures? In my head, this doesn't look anything like a double wall tip and wouldn't look very good.
