05' GTO exhaust resonator??

tiger gto · 02-20-2006, 06:24 PM

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

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.

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!

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.
