would an itr muffler make a difference in performance if it was swapped over a stock LS muffler? What is the difference between the two? Thanks..

 

the ITR has alot better flow......30+% i believe

 

i think the whole exhaust...cat-back and muffler account for the 30% increase in flow

 

Yes You are partially correct.

What also adds to the better flow is the larger diameter pipe on the ITR exhaust....

 

I have the ITR muffler in my GSR with the stock B pipe. I can't really feel anything different, but it is a bit louder.

 

Any company makes replica of type R cat backs? They are so hard to find...

 

same here...just get the whole cat back if you are going to do itr

 

I had the Type-R muffler mounted to my stock B-pipe for about a 1.5 months and I notice an improvement in acceleration above 5,500 rpm and I only slightly deeper exhaust tone.

About a month ago, I had the Type-R B-pipe lengthened and installed and the improvement is very noticeable and above 5,500 rpms the car really pulls hard (more so than above). The tone is just slightly louder than the stock B-pipe and Type-R muffler.

I have been extremely pleased with the performance of the Type-R cat-back exhaust and I also like the sound of the exhaust. The sound is only slightly louder and deeper than stock (which is nice and it doesn't attract a lot of attention).

I highly recommend the Type-R cat-back exhaust . BTW, I bought mine new.

 

So you bought the whole Type R Cat Back exhaust and then had the Type R B-pipe lengthened? This is necessary, right, since it won't directly bolt onto our GSRs?

Yes, for a '94-'99 GS-R you will need to have the Type-R B-pipe extended by 4.5". Here is a picture of my lengthened Type-R B-pipe.

BTW, I had a 2.5" exhaust flange installed for a future JDM 4-1 header and a 2.5" hi-flow cat.

i have a itr b-pipe already lengthened for sale if anyone is interested...its in great condition, but one of the bolts (where the b-pipe meets the axle back) will have to be rewelded on...the guy who took it off was a bit careless...anywho...its only $50...get it out of my garage!!!!!!!!

And, as for impressions...i think it did make a diff, i now run a greddy b-pipe mated to a r muffler. muffler is slightly louder than stock as others have said, but i noticed hardly a diff in performance...

Any difference in materials? I think I read somewhere that the ITR muffler was stainless... is this true? How about the B-pipe?

 

The Type-R cat-back exhaust is 57.2mm (2.25") mandrel bent piping [an increase of +6.4mm~8.6mm over stock] throughout to increase air flow. The muffler is a multi-chamber design, and does a wonderful job of dissipating sound. However, the funnel-shaped piping in-between the chambers makes it a very free-flowing exhaust. Furthermore, in order to lighten/strengthen the parts, stainless steel was used.

The complete Type-R exhaust (header --> muffler) flows 30% better than stock. Here is a diagram which shows the differences.

 

 

here is something that is gonna sound really strange. how about this. getting an s200 muffler....since it has a twin-loop design to it, and get custom piping from the cat. i believe the s2k muffler is a 2.25 in design correct?

 

If you want to see some good side-by-side photo comparisions of the GS-R and Type-R catbacks, go to http://www.imagestation.com/album/in...?id=4292381039

 

you said you bought the itr catback new. did you get it from a dealer? and if so how much was it?
thanks in advance bsq.
btw love the trunck brace and itr rear sway bar articles you did.

 

The B-pipe (part #18220-ST7-R60) has a dealer list price of $206.02 and the muffler (part #18030-ST7-Z61) has a list price of $241.67. I would recommend checking out acuraautomotiveparts.net . The B-pipe is $164.81 and the muffler is $193.33 . I actually know someone that works at an Acura dealership and I got the B-pipe and muffler for about $300. One good thing about the buy the Type-R muffler and B-pipe, is that they have a lifetime warranty. If they ever go bad, Acura will replace it free.

 

Are all the years of the Type R's exhaust the same? Do they differ certain years like the 2000-2001 GSR's?

 

when i first swapped mah EK wit a GSR motor i used a ITR exhaust for a lil while it just like driving a Integra lol sounds like one 2

 

but it was very difficult to get entire system 2 fit on mah hatch

 

It's a brushed aluminum diamond mesh. I cut it and attached it with zip ties.

It cleans up the front and rear end of the car, IMO.

 

just get hytech exhaust

 

will the itr exhaust+muffler fit on a 00 gsr?

 

A Hytech exhaust would be nice, but you are looking at ~$950.
