I have i/h right now .. going to put an exhaust int he summer ... will there be a big diffrence i always here how the header is useles without the exhaust is it true to that great of an extent of it being worthless ?

It is a system. It all works together. You need to consider your power goals in the long run, size your exhaust piping accordingly, and buy all your components so they work together.

i'm on ti already i've read articles and am going to go with a 2.25 mandrel bent with itr stock exhaust i want low loise levels. but you know how like exhaust does .. 2whp or whatever and header does like 5whp .. will there be more if there both there togther instead of like 7whp .. will the pair do maybe 10whp ? somthing like that

the stock cat will be the big choker, get a random tech hi flow, theyre also 50 state legal and flow about 6786087 timesbetter than the stocker

hmm and with i/h/e and cat .. i'll be sure to pass emissions ? might look into it

exhaust definitely helps out. especially if you opt for the whole "package" muffler, larger piping, straight pipe, ect. and power increase also depends on what muffler you get too. but i definitely recommend an aftermarket exhaust setup.

so muffler is important ? i figure the itr muffler would be good since itrs have 195hp and i wont have anywere close to that so flow shouldt be a problem with that + it looks stock and is low in noise lvl compared to afermarket. let me get your input on that

mr_mbuna

Come on Racer, go through the articles AGAIN and talk to Michael Delaney... items do NOT produce power individually... they are all restrictions and you can't assign numbers to each item since it all goes together. The only thing to accurately measure is the gain from the entire system.

The problem with the ITR and similar A'PEXi World Sport exhaust is that they are NOT straight-through exhausts... they have a pipe into the muffler, some baffles, and a different pipe out of the muffler. A straight through like the Comptech will give better gains, and with a Quiet Tip Insert, the Comptech is a power adder with straight-through design and Stock Power Levels.

i know what u mean about not assigning hp #'s i was just trying to see if the package would hit up more overal than just piece by piece. so the itr muffler is a no no ? str8 through design is the way to go... but i hate the look of those canister type things

mr_mbuna

Noise is still the Primary Engineering Concern with ITR exhaust system. SurferX, on Team-Integra (man it just keeps coming up doesn't it?!?), put a Hytech custom exhaust on his ITR and gained something like 20 whp. Yes, the Hytech costs like $1500 but that shows what a good exhaust will do.

yea i saw surferx's dyno real nice will it be a huge difference between an itr muffler or a str8 through in power.. noise thats basically i think what i want to know ... oh yea also .. a mufflers shops custom bent cat back ... compared to a already made one whats better ? sorry for the n00b questions but you guys are being real quick to take care of all my exhaust questions tonight

mr_mbuna

ITR exhaust isn't a no-no... It is a better exhaust than LS/GSR have... and it is only $200 used so if you're on a budget go for that. I, however, decided the Comptech unit was worth the money. On here (honda-tech), Dr.Rab01GSR is selling his Comptech 4-2-1 header in perfect condition and I am sure you can find a used Comptech catback if you want it.

The Comptech uses an oval muffler, not a round coffee can.

the muffler is definitely important, air flow definitely differs from muffler to muffler. currently my exhaust set up on my 98 gs-r is... 2.25 piping, no cat, and an axel back A'pexi N1 muffler with mandrel bent piping. i noticed a nice increase in top end power and a definite change in sound, which contrary to some opinions, i love. the N1 owns!!! hehe. an itR set up would for sure be an improvement though if that.s the route you're going to take.

i like the way that comtech muffler looks .. how much for that .. and its 200 beans for just an itr muffler or full itr exhaust ??? good god thats mad loot

mr_mbuna

Uh oh... welcome to Car Modification. More Expensive Than Crack.

The full ITR exhaust, from the cat back and maybe including the ITR cat, hovers around $200 used online. Think that's expensive...

The Comptech catback exhaust is now around $650 new. http://www.diabloautosports.com/ for a new one. Used, they run around $400 in good condition. The Comptech header is $369 new, for the MIG version. A catalytic converter will run about $160 or so.

i'm gonna get teh itr catback new .. unless i can find it used in great shape .. but the oem itr catback will bolt up right up to my 2k ls ? or do i have to modify it a little . ragejed told me a new flange would have to be welded on

Mikes01GSR

I have a Comptech Axle back for sale right now....it bolts right up to the ITR
B-pipe. I'm selling it for 160+shipping!!

mr_mbuna

You could do the ITR catback... new its probably gonna be real pricey and not worth it. Or you could buy Mike's Comptech axleback (usually what, 350 new?) to your local muffler shop and have them install it on your car with custom 2.25" mandrel bent piping. Whatever you wanna do.
