Flowmaster Y Collector How much will this help the rasp on my jet hot o/r y pipe?? I plan on cutting my rear cat back off and dumping the exhaust after the muffler. I want to put a Hooker muffler after the collector and dump the exhaust after that, whatcha think?

I did the flowmaster mod to the mac ypipe. It still rasps but it might be from the ball flange collecters at the headers. Adding the flowmaster collector might not be worth the hassle. Ive never found any documented dyno gains from the mod.
Here is a link of an exhaust with hooker lts, ory pipe, and 3" magnaflow muffler dumped under the car. It sounds pretty good actually. Magnaflow makes the 3" muffler with 4"x9" case. They make them with several lengths. Ground clearance might not be too bad. You can get the muffler for under $100 which is much cheaper than any catback.

I bought a j-bend with the Flowmaster collector....I'm gonna use it to graft into the MAC y-pipe. The sole purpose for doing this is to eliminate the rasp...I hope it works...if it doesn't, I'll try something else.

I have the 2 cutous, mandrel 3" bends, flowmaster y-collector and 4" to 3" reducer. I also have a Hooker catback ordered to help kill the rasp.
If that setup fails I'll weld the Borla XR1 muffler that I currently have back in the I-pipe.
If that doesn't work I give up

No one knows why the off-road y-pipes rasp, but we all try to fix it. It's hard to fix a problem when you don't know the cause. So far, some people have only been able to "silence" the rasp.
Why doesn't an x-pipe rasp? It is effectively a 2 into 1 collector, it just splits again immediately after the junction.
I personally think it has to do with the unequal length of the arms going into the y-pipe junction and the unequal length of the header primaries...but I can't back that up.
