Do they really make any power? How is the flow? I just wanna make the exhaust on my 98 gsr quieter (trust evo.) and was wondering about the flow with a itr exhaust, or im just going to put a better resonator on the trust

 

people have said that they noticed no power loss when they changed from an aftermarket exhaust to a itr oem exhaust but dont know from experience

 

I think the oem itr exhaust if roughly around the same size as a comptech cat back, so you may see similarities in horse power gains from the two. Check around for people who have dynoed their car after replacing the oem one with an itr exhaust.

 

There aren't too many people who have done that.

 

just get the axle back.
it's 2.25 and looks nice, stock and stealth.
for the b pipe, go custom...with no bottlenecks.

 

The bottle-necks aren't anything to get your panties up in a bunch over. I got the whole ITR catback for 140. I believe it flows 30% better than the Gizzer exhaust.

 

i took a tanabe racing medallion catback off my itr and put the stock catback on, and felt no power loss, and its much much quieter

 

About a month and a half ago I replaced my stock cat-back exhaust on my '94 GS-R with a new Type-R cat-back exhaust. I defenitely noticed a increase in power, especially above 5,500 RPM. The sound level of the Type-R exhaust isn't that much different than stock, but it does have a deeper tone.

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.



Just an FYI, the Type-R B-pipe will need to be extended 4.5" to fit properly on a '94-'99 GS-R.

 

Once again...BSQ comes through with some serious knowledge!

 

thanks mucho for the info guys,

BSQ: Your get 2x for the visuals amigo

thanks again. i had a magnaflow put on as a resonator today, the previous jackass had a friggin Cherry Bomb on there, which pains me since it it a greddy evo canister and tubing. Its still too loud for my taste, so i'll off it and get an oem ITR exhaust. i have dc headers so itr headers arent too necessary

i appreciate it, you "R" owners are definitely a class above the majority of the Teg board guys
