Hey guys, I was checking out the underside of my 99 GS-R and I see a second small muffler in the center (a resonator). Has anyone cut this out and replaced with a straight pipe/high-flow muffler?

that is the mid-muffler used to quiet the exhaust

 

[TheGSRGuy]

Exactly.....if you remove it, what does it sound like (besides louder)?

 

[Dr_GSR]

When I got my cat back put in, I didn't have them put one one. So I guess I don't really know what it sound like when you remove it from the stock piping. Anyway, I know quite a few people that have had theirs removed. It makes it a little louder, not TOO big of a difference. And I guess it give you better air flow too.

It doesn't improve performance any if you remove it, just makes you louder. The resonator is not a restriction to exhaust flow, that's not how they decrease noise.

mine doesn't have a resonator and it can be kind of annoying. Just leave it on

coffee can and bumble bees will be following you....not to mention the men and women in blue to write a nice sound violation ticket and make you poorer....
that would not be a very smart thing to do... but maybe you like coffee close to your car? capuccino? with some caramel drizzled on top or vanilla sprinkles or cinnamon?....

I didn't get mine put back on until after I got a ticket.I learned the hard way.I can't afford the extra attention.Plus the exitement wore off very quickly.Keep it on.My 12 cents 10 cents are free.

had it taken off last night welded for $20 at monroe and it sounds incredible (good incredible that is)

Resurrecting an old thread of mine! I have the ITR catback now but even that has the resonator. So I decided to leave it. It doesn't restrict flow.

haha yea.. just figured id give a positive testamonial

plus... yea i know this may be the old butt dyno thing, and i hate the butt dyno, but i believe it may have given me a better throttle response. The girl that I bought it from had the whole exaust system replaced using a generic muffler and resonator, and i think that may have created somewhat of a restriction. When I looked at the resonator after it was off the car, it seemed to "pinch in" on the ends and had some custom bent piping bent in on the ends... pretty gay if you ask me... anyways my point is that it "seems" faster, but is probably just because of getting rid of that restriction.

 

[TheGSRGuy]

Many people associate a louder sound with performance increase. I'm running an ITR header, ITR intake, and ITR catback...and it is very quiet but gives decent gains.

Want to see what I mean by sound not equalling performance? Remove the cover to your stock airbox. It will be hella loud but will actually slow you down.

man, a lot of Dan's threads are coming back from the dead...it's becoming a downright Irish wake around here...or is it a Haitian Voodoo?

I am part Irish.

Why are they coming back? Those are some old n00b questions of mine from back in the day. Common ones mind you. I guess people are using the search feature!

 

[aepunk04]

haha yea thats how i found it.. i had to get my muffler rewelded and decided i'd research giving it a try with the resonator off, because i knew the system was not OEM... good thing i did

Blarney! Well miracles never cease! Put on some trad and have a Guiness Stout on me!

 

[luckypnp]

ok people remember helping people is fun.. sometimes funny.. so im guessing this person has a stock exaust, so there for leave it on there, ive heard straight pipe turbo setups that are quieter than mine..

 

[aepunk04]

ill have a guiness on the house (TI) anyday

yea my exaust is just stock, but generic, but i took out the resonator and put on a R1 muffler until i get a full apexi n1 catback

 

[hootb18]

lol dan, when i saw you were the topic starter for this subject i was thinking to myself, "you gotta be kidding me! there's no way in hell he is asking this question!". well all i gotta say is i thank my lucky charms thats not what happened.

I once had a dream where I pissed on the Blarney Stone.
