Can anybody help here? Is that big square exhaust "resonator" really necessary, or can it be taken off without any ramifications.

I still gotta believe that thing is stangling some horsepower. Is THAT particular set up "necessary"??

nope cut it off and put str8 pipes or put an xpipe:cheers

Dear EEZ GOAT, ...Will it sound that much better, & will I pick up any gains?

I had put flowmaster "delta flow's" on the car last year, ..but felt that resonator was still impieding power, & sound some.

Cut your cat's. That's when you'll notice a big difference in gain of hp.

:agree

best thing to do is get and x-pipe to still generate some backpressure, for
it is needed for high rpm performance unless you tune it other wise.

took mine off, replaced it with a x-pipe...I didn't like it so I put the resonator back on. It adds a deeper tone and has straight thru pipes in it. just an fyi! :cheers

x pipes are not for backpressure, they are to smooth out the exhaust flow so your car doesn't sound like two civics with fart pipes, without being as restrictive as an H pipe.

Here's the inside of the resonator. The pipes have perferated holes to equalize the pressure.

they suck lol

Here is some info for you... great reading by a well known Expert, David Vizard.

You can take the resonator out if you wish, but it is my belief that the resonator is what gives the 05/06 GTO its unique sound. JMHO....

mufflers

Can I just cut off the muffs and replace them with flowmasters.But still keep my chrome tips.

I read an article about the resonator on a web site and the article stated that's what the resonator is for, the unique sound
