alright so ive fixed the exhaust leak and it sounds a little better but its still raspy as fuck past 3k rpms....also since the header install, when im in 2nd gear the rpms will randomly drop or rise when im holding the pedal steady. wtfffffffffffff is going on....this is annoying me so muchhhhh.

bump**wish i knew man

eclipsemodder · May 9th, 2011, 11:12 PM

yeah its bugging the crap out of me. consuming my thoughts lol

joeyb · May 9th, 2011, 11:13 PM

hmmmmmm....ok - could you put up a picture of your entire exhaust system or describe it in detail as to what is in there and what isn't. is there any stock piping in there at all? resonators? cats?

you may be leadking around the header gaskets, did you replace all of the exhaust gaskets when you installed your headers? that needs to be done. you have the GS, right?

eclipsemodder · May 9th, 2011, 11:21 PM

Okay so the obx header to begin with, gaskets were replaced the header is bolted down hella tight, where the header bolts up to the small pipe it comes with it is bolted up hella tight as well, then it is welded to the stock piping (perfect weld no leak), then there is the third cat right after that, then it goes down to where the resonator was deleted and a new pipe was put in, i fixed the leak earlier then it goes through stock piping to the hks muffler

eclipsemodder · May 9th, 2011, 11:25 PM

i can understand the raspyness for the most part cuz its prettty much straight piped but the rpm dips is a concern, there is no check engine light either

Matched88 · May 9th, 2011, 11:52 PM

its ONLY the rpm gauge doing this? you not feeling anything what so ever?

eclipsemodder · May 9th, 2011, 11:55 PM

no im feeling it too.

Matched88 · May 10th, 2011, 12:08 AM

does the car feel like its jerking/having hiccups when its happens?

usualy rpm jerking is signs of ignition problems, so i would check things like plugs,injectors,pump,pump relay, and also check out throttle sensor/relays

eclipsemodder · May 10th, 2011, 12:11 AM

yeah kinda feels like it hiccups. do i maybe need to tighten o2 sensors more? this only happened after i installed the header so i doubt it can be anything more then o2 sensors?

eclipsemodder · May 10th, 2011, 12:25 AM

and i still dont understand why it sounds beast when its in neutral being revved but they when im driving it sounds like shit. wtf. blah

Matched88 · May 10th, 2011, 12:39 AM

i would say first stop by an autozone and borrow a scanner to see if there is any hidden codes before further messing with the o2 sensors because i have had previous cars throw codes without me knowing until i voluntarily scanned my car, but yes i would check those out and any of the other things i listed for "just in case" situation

DustinH · May 10th, 2011, 12:50 AM

Do you have spacers on your lower o2 sensors?

eclipsemodder · May 10th, 2011, 12:51 AM

i do not

DustinH · May 10th, 2011, 02:43 AM

Get some on those lower sensors.
