Would it be worth it to throw an ITR muffler on my GS-R? I can get one for around $120 or so I like how they look, but what would I be expecting out of performance/sound?

 

Wrong fugging forum.

 

Let's try to improve the current situation on these forums in a friendly way (I've been guilty too.) I think it's the best way. :

skafia, you would get a better response by posting in the integra forum, as you drive a GS-R, you will recieve a better & more accurate response by posting there.

 

Ah well... I thought cause it was an ITR related topic I could post it here... I guess not

 

Let me be considerate...

We do not own GS-R. So, how would we know for sure how ITR exhaust performs on a GS-R. Wouldn't it make a better sense to ask the GS-R owner with the mods?

And, yes, a ITR muffler flows better than a GS-R muffler. But, it's all about "synergy" of parts you have to make any kind of gain... just slapping on a better flowing exhaust does not guarentee a gain in HP.

 

skafia - Not sure how much more flow you would get with just the muffler. If you could modify the ITR b-pipe to fit a GS-R (not even sure that's possible), you'd see more improvement

BTW - Brian*Black99si ran an ITR muffler for a bit. Perhaps he can help you out too.

 

... and incidentally (shameless plug in haha) I'm selling my b-pipe.

 

it has to help because it came off a type r... just saying type r in your car while racing will give you a little on the top end.

 

When I got my Tanabe exhaust I sold my stock exhaust to a friend with a 2000 GSR. After we installed it, he couldn't notice a difference in power or sound.

Get an aftermarket exhaust.

 

You know how an exhaust makes 2-3 more hp. Well the Type R muffler flows 30% better than a GSR muffler. So 30% of 3hp is 0.9 hp. Only 0.9 more horse power.
I think you're better off getting a straight through exhaust.

 

A while back I've remember seeing pictures of a cut away of a type r muffler. It is a continuous channel that goes in, makes a 180 degree turn, comes back and the makes another 180 degree turn and exits the muffler. The air flow is preserved this way. A conventional muffler is like a big chamber with straight walls or plates placed in it. Here the air come in the muffler hits a wall straight on. It then has to go around it and all the other plates it encounters before it leaves the muffler. The air flow is definitely disturbed this way and more backpressure is created, but this does make the muffler quieter. This is why an aftermarket muffler makes very little and in most cases no increase in power on a stock ITR as compared to upgrading the muffler on another car.
