Will a bullet eliminate.... If I were to put a bullet muffler in my I-pipe before my cutout will it help eliminate that horrible drone/rasp at 2000rpms to 2500rpms?? If so will it effect performance. I have no cats as well. Any help would be appreciated...Rockls1

Re: Will a bullet eliminate.... I would love to get a x-pipe except I currently dont have any headers, I just have a ORY-pipe, and I dont know of anyone doing a xpipe without any headers. Thanks anyways...rockls1
Re: Will a bullet eliminate.... I have hooker LT's and ORP, I put the 18" bullet in my I-pipe before the axle and it took care of 90% of the rasp/drone. It's still there, but much more muffled.

Re: Will a bullet eliminate.... THanks guys for the feedback...will the bullet affect performace. And does it make it sound better when the cutout is open? What about when the cutout is closed?
Re: Will a bullet eliminate.... I'm interested in this too. I just got Hooker LT's installed with a custom y-pipe and a cutout right before the axle and I'm tired of the rasp already. Will the bullet muffler hurt performance any? Thanks alot.

Re: Will a bullet eliminate.... It won't hurt performance. You can drop a tennis ball straight through a 3" bullet. I run dual 3" bullets on my 9 second car and there is no performance loss so far as I can tell.
You can run one in the intermediate pipe, two in the Y-pipe, or both.
And yes, it'll get rid of %90 of your drone. <img border="0" title="" alt="[Cool]" src="gr_images/icons/cool.gif" />

Re: Will a bullet eliminate.... Like the Colonel said they are straight thru and cause almost no restriction. I couldn't tell any loss in performance after I added mine, still ran the same times just with less rasp/drone. I really noticed how much it killed the drone in 5th gear from 55-65mph, it use to be almost unbearable for extended periods of time.

Re: Will a bullet eliminate.... Thanks for the replies fellas, so will only one bullet in the I-pipe be all it takes to eliminate the drone/rasp? Or will I need 2 in the y-pipe??

Re: Will a bullet eliminate.... One in the I-pipe will get rid of most of the drone. I'd say %85-90 is what it did for me and I was satified with that. Dunno about two in the Y. Haven't tried that.
Re: Will a bullet eliminate.... I have tried both set-ups.
With my MACS I had the dynomax 12" bullets in the Y-Pipe. It cut the MAC drone which occurred from 2000 - 2500 rpm down to only being noticable from 2000 - 2200 rpm and being less bothersome at those rpms.
With my Grots, I have a single dynomax 18" bullet in the I-Pipe, followed by a QTEC. It got completely rid of the drone (which was not as bad the MAC drone) and I do not worry that my cut-out is after the bullet.
Pros & Cons:
I-Pipe: less expensive (only one bullet to buy and install) and no ground clearance issues. May not work with a Sphon style torque arm.
Y-Pipe: Looks like you have cats during a visual inspection. However, I flatten (not badly) my bullets on speed bumps.
