Default ANyone just running bulets/eliminators?

Have 2 dynomax bullets and 2 dynomax super turbos on the car now, dual 3"s with no crossover. Resonance is unreal at most levels.

Been in a few non LT5 Vettes with elims and its loud but doesnt drone at all.
Was thinking about chucking the turbos in the trash as Im getting tired of the ricey big tips, leaving the bullets on and welding on some LT1 tips I have.

Feedback?

ron , i have accumed 4 different exhausts we could do a mix of any of them to get what you want .1) complete borla 2) desert deveoplement 3in . 3 flowmaster (the one that you heard ) 4 )dr gas spin tec that they built for me at their factory 5) complete stk 90 6) complete stk 91. 7) corsa thats on the snat 475 zr1 i just bought. so i think i have become neurotic about exhaust . just found out its worse than I thought . but we could try to get what your after let me know . are you going to keep the z. if not i may have a guy interested in it after riding in my new one .pm me maybe we can hook up .brad

Im just looking to make a change and try something I can do myself, wont cost me anything. Worst case scenario I dont like it and a system is in order eventually. Right now I dont want to pump $ into the car.
If your friend is serious give him my number, somewhere in the 17XXX would be the bottom otherwise it stays

I'd actually wondered if going to Super Turbos would remove some of the drone/vibration of my exhaust instead of the Ultraflows. Especially after hearing that's what Callaway used for the SN exhaust. However your description of your system makes me think it might not help.

I'd only call my resonance unreal very occassionally. So maybe you could try swapping the bullets out for a '93+ or LT1/4 resonator? You could probably pick one up for free.

You want noise Ron ? I can't quiet down the white car for s&it. S.O.B could get rid of any household pest by just pulling into the driveway.

i did this about a month ago and couldnt believe the diff . i had an old road sign and made a plate that bolted above the mufflers .i bent it down so so it came down to thebottem of the back of the mufflers .cut a Uso it went over the pipe i put 2 layers of dyna mat extreamliner that they use for the underside of the hood on the top of the piece i made . now i use the desert develpoment 3 in exhaust and have no resonance at all. credit goes to bfriend that owns his own sound engineering co in sanfracisco. they deal with quieting the sound from heating and airconditioning in skyscrapers. what he said is to get it (sound absorbed before it gets into the cabin of the car). the other thing he shared was to get the exhaust tips to end 2 in past the rear exhaust opening . all i can say it worked way better than i first thought it would .

I think its the 3' pipes that make it drone, think they are too big and the exhaust speed is slow. That, couple with no central resonator...

Brad no, that doesnt include the motor.
