Default Borla header question

Hey people, the new generation header from Borla--is that an exact fit, or is there any cutting or welding? I spoke with a salesman 'cause the website said minimum welding needed for fitment--he said you have to cut a pipe and then re-weld it. I thought you could buy it and slap it in, any thoughts? 10-Q

I didn't have to do anything but bolt my Borla Header set in on my 99 Legacy GT. Yours should be the same.

The "new generation" Borla header removes that problem that the salesman mentioned.

On the new gen headers, are people having any CEL's? I heard that the old ones set a converter too low temperature or something CEL. I guess a few people had luck with wrapping their headers and the CEL was less frequent. anybody?

Default Thanks guys

I was 90% sure that it was a direct bolt on, thanks for the info. Looks like a great mod. Thanks for the replies.

The cat inefficiency light mainly comes from high flow cats not headers.

People have had issues with Missfire codes with these headers. Some people have attributed this to the way Borla designed the pulse sequencing when they hit the final collector. We think Borla designed the pipe lengths so the exhaust pulses coming from one side of the engine either take significantly more time or less time to hit the collector then the stock header section. When the front O2 sensor sees this variance it throws the Missfire code.

MY99 2.5GT - interesting, I wonder if they've done anything to the new gen headers to cure this problem, I don't like CEL's

Default Borla 2.5 header

I just ordered the 4th generation header. Only $264.99 shipped. That includes gaskets and bolts! From Performance Center.com I believe quality and fittment issues have been addressed with this new header. I'm not sure about CEL's, but I think it has to do with each unique set up. Thanks guys.

I just put an order in with these guys for gen IV header as well. Borla stuff is actually 5% off this weekend, I got mine for 251.74 + 8.25 for shipping. I verified that they come with gaskets and bolts as well. I think I will be ordering a MIL eliminator as well so when I get my test pipe / intermediate pipe made up I can avoid the inedible CEL.

I had the cat efficiency code with my gen 3's...on and off. I picked up the Pony express MIL eliminator...no more CEL's.

I just need to get the headers back on the car...typical gen 3 weld failiure at that "brace", that I had TIG'd back up at work.

pony express mil eliminator?
what exactly is that? is it a fake o2 sensor that generates a signal of .1v .9v .1v etc ?
has anyone else had to machine their header holes larger?
thanks for the input

BoB O: the brace on the gen3 are the cause of the cracking. Remove the brace and you have a gen4


95% of the gen4 cylinder head flanges need to be reamed out to slip on easily. I just pulled on the pair of primiary tubes and it slip on.


Did you guys really get gaskets and bolts with the gen4? All I got was a lousy Borla baseball cap.

test pipe huh

I called and verified with perfomancecenter.com that the header comes with gaskets and bolts, I'll find out soon and will let you guys know.

As far as the test pipe goes, we shall see. If I can get a midpipe fabbed for cheap enough I will do it just for track days. I dont really want to run a test pipe all the time, not environmentally sound and it really does make the car stink. I did find on my old civic that was NA also that I picked up some power without the cat, it was nice but probably not worth it in the scheme of things.

FWIW, I've done the test pipe route already and had to take it off because I was going deaf. It made the car hella loud (borla headers+modified random tech cat pipe+rallispec N1 catback w/o resonator). However I should note that the headers cracked during this time period so I'm sure that didn't help the noise. Not really sure about gains from it (tired clutch). I still have the pipe so I may try it out again if it doesn't get sold once the headers go back on.

I didn't get gaskets or bolts when I ordered my header set about a year ago from www.performancecenter.com

lol, cats definitely quiet the exhaust system down quite a bit. I've found that having a resonator added will quiet the exhaust but it will still be louder than with a cat in place, although it will be a deeper tone.

so I checked out the pony express web page, and they say that you only need their product for a gutted or high flow cat, so this wouldn't help out a CEL with a borla header would it?

I would get the header first, then if you get a CEL order an eliminator. It seems not everyone with the gen4's are getting CELs. I 've NEVER had a CEL because of any mods I've done...you might be one of the fortunate.



...so, are gaskets and bolts really included with gen4 package???
