I'm not sure if I fully understand your question. Are you asking, whether or not an ITR exhaust will give you hp gains??

If it's just the axleback, then you're not going to see much gains. When looking at exhausts, you need to consider the whole setup: header, cat, and catback. If you upgrade the whole exhaust, then you'll see gains.

FWIW, I've read that the complete ITR exhaust will give 30% gains over a stock LS exhaust.

 

yea i got headers so i just take it to the weldin place an get a 2.5 bac

30% gains in what?

You got to be kidding, 30% in just bolt on, even in the peek performance only and best setup, is almost questionable. A turbo or cam work seems more likely.

From what I read 10-20HP on a full bolt on setup IHCE is more likely, that's like 5-15%.

The 30% increase that timmy8151 quoted is the amount of flow improvement over a non-ITR exhaust. In other words (and note that these are completely arbitrary figures) if a stock GS-R exhaust is capable of flowing 250 CFM, then the ITR system would flow 325 CFM.

I do remember reading that about the flow for the muffler somewhere (probably back in '97 in C&D). Obviously that 30% improvement is not alleviating a bottleneck, considering the ITR's 195HP is only 14.7% higher than the GSR's. And that 14.7% includes the affect of a p&p head, higher compression ratio, yadda-yadda.

A 15% increase in power output is no small accomplishment with a motor that is already producing close to 100 hp per liter, especially when it must maintain OEM reliability, fuel efficiency, etc. The exhaust system undoubtedly contributes slightly to the ITR's power improvement (though the ITR system still isn't terribly free-flowing, and still contains a number of bottlenecks and a chambered muffler). Of course, even a purpose-built performance exhaust system with large diameter tubing and a straight-through design won't yield large gains on a relatively stock B18C, so you are indeed correct in stating that the performance improvement of the ITR system over a GS-R system is not very significant.

 

what would i have to do if i wanted a itr exhaust on my LS?

No modification is necessary. Just purchase a full ITR cat-back, and it will bolt right on to your LS.

 

I just received my itr muffler that i bought from Bonndock Saint...I just put it on today on my LS and I love it...Wish I could've got the whole exhaust though...I will post pics tomorrow along with a new thread on it...

 

I would save the money and get something else. Although the ITR exhaust is 2.25" diameter piping, where the flanges meet, it reduces to 2"... I know of 2 places for sure, the axle-back flange and at the cat-end flange of the b-pipe.

u wont gain hp unless u change ur piping into 2.5" all the way no cat or test pipe only.. but dont expect too much hp coz its juat a bolt ons..

 

ok lets say forget the itr exhaust an i by an another exhaust wuts better bolt on or weld were is the hp goin to come from more

WTF are you talking about??

 

<TABLE WIDTH="90%" CELLSPACING=0 CELLPADDING=0 ALIGN=CENTER><TR><TD>Quote, originally posted by timmy8151 &raquo;</TD></TR><TR><TD CLASS="quote">WTF are you talking about??</TD></TR></TABLE>engrish ownz you.

i think (and i'm going out on a limb here) he was asking whether a bolt on exhaust is better than one that is welded together. a bolt on if fitted properly should have no leaks and perform identically to one that is welded closed. obviously the bolt on has the convenience of being removed without hacking apart the exhaust.

btw, 94integrals04, you really should consider rereading and editing your posts before you put them up. people can't help you out if they can't understand what you are saying. i apologize if english isn't your first language, but its often difficult to read what you write.

 

this damn kid is crazy....what are u talking about???????????
