OBX EXHAUST
Yeah...I know this is an old thread....I know how some peeps complain about new threads on an old topic.
Anyway,
I just finished my exhaust project and I like the way this catback sounds when you get on it
I only have the catback and , to me, it sounds pretty decent for a $320 setup. It has enough throatyness with the silencer in for me. Mainly needed something fast and glad I replaced it because the stock was broke right before the muffler and had another leak between the cat an resonator.
Only took about 4.5 hours with the rusty stock parts.
Just wondering, will I see any improvement in the following: mileage or power?

An "increase in HP" will cause more gas to be consumed thus decreasing your gas mileage.
But chances are since the gains are so minimal with an intake and catback, your driving habits will be more of a determinate of gas mileage.

Back at the topic at hand...
Your gains will be very minimal with the mods you brought. Only thing those parts do is add more sound than anything else (which isn't bad, don't get me wrong). I wouldn't be expecting more than 1mpg, honestly you've maybe added what, like 5hp? Now if you got a Y-pipe... those are some ponies/mpgs right there... You just gotta be gentle with your right foot, cause the sound is addicting.

Since when were EPA estimates so accurate? They're ESTIMATES. I've gotten 30+mpg multiple times in Manhattan, it doesn't matter that I stay in neutral and I'm usually going downhill most of the time, all that matters is the final result.

Garbage as in rusted? Damaged? AFAIK the intake and cat back on our cars aren't the real restrictions... Either way, good job w/ the mod then, if you're happy then it's money well spent.

sweet jebus!! how about instead of bumping a 5 YEAR OLD THREAD to tell us you just installed the parts mentioned in the thread then ask what the result in performance would be. GO OUT AND GATHER DATA then come back and bump a 5 YEAR OLD THREAD saying "yes or no" to the original question based on your data.

I get so sick seeing the responses like: "search more" or cut and paste a link....if someone doesn't have any YES, NO, or NO CHANGE type of answer........then don't answer....it is that simple. I can be a jerk like that too....but I choose not to....if I think I can help....I will....simple as that.
Yes...I may have a lack of forethought, but if someone has done the research already...then it doesn't make sense to do it again....I like effective answers, not "do a search" answers.

I am not trying to **** you off, but I wanted to find out if any other orgers were noticing any improvements....it is just a simple YES or NO or NO CHANGE......that's all I get so sick seeing the responses like: "search more" or cut and paste a link....if someone doesn't have any YES, NO, or NO CHANGE type of answer........then don't answer....it is that simple.

OBX CATBACK EXAUST MPG,POWER, and EXHAUST NOTE UPDATE
I have been running my OBX r-type exhaust (my max has 174k+ on it and regular maintence...oil, plugs, air filter, etc... is done religiously) now for about a month and 3000 miles and here are some of the results I have been getting so far:
City: 19-21: Slightly lower than stock.....has a lot to do with me getting on the gas a little more too. Probably get about the same if I take it easy.
Highway: 70-73 mph: I have been averaging about the same..25-28 mpg
55-60 mph: I have been getting closer to 30mpg!!!!
Power difference: I have not dynoed, but I do notice a slight increase in acceleration to highway speeds....nothing scientific, but I definitely notice a difference.
No other changes have been done to the exhaust, only the catback. I did NOT remove the silencer either.
Sound Note: Compared to the stock note, I have a much lower note at around 2000 rpm and the exhaust just roars at WOT near 6000 rpm. (yes, even with the silencer in!!!) At about 55-60 mph, there is a little drone from the exhaust because of the cruising rpms at about 2500 rpm. At 70-73, there is hardly any exhaust noise within the car.
Overall, I am happy with the purchase and my install job. For about half the price of a stock replacement....I would recommend the exhaust for anyone on a budget. It only cost me about $380 with shipping.

I replaced the muffler and resonator on my car and notice greater reponse atfter 5000 rpm...the car redilines a lot easier and seems less stressful on the engine.
Next mod may be the y-pipe hehe

Honestly I would like them to lock this one now because there really isn't any need for the thread to continue on this topic from my standpoint.
There was no data on the topic before and now there is.....sooooo, NOW THE MODERATORS CAN LOCK IT.
