I had this same problem the issue is the EGR valve. After I installed the pacesetter headers a noticed the stutter. Turns out, after a bit of online research that our EGR valves work off of negative pressure (back pressure) from the exhaust system which with headers and a upgraded exhaust system the majority of the back pressure is lost, at least enough that the EGR will not function properly. Our EGR valves kick in above 2500 rpm causing the stutter. To test: -In park, slowly rev the engine to verify where the stutter starts -Disconnect vaccum line feeding EGR valve -Slowly rev engine and see if the stutter is gone. This was the solution in my case. You may need to plug that vaccum line and you may also have to adjust the fuel/air mixture. A permanent solution would be to track down a positive pressure EGR and fab it up to fit; then again you could just put a block off plate in too. Have you had much like with your NTK O2 sensor?

Works had me tied up for the past couple months, I'm now back in Burlington, WA I look for a local dyno here and get back with some results. Yeah, the O2 sensor had to be installed after the cats cause there just wasn't any room to install the x-pipes pre-cats.

Let's see some pics.... I like to see how they piped your system in compairson to mine. Oh, swapped out the Magnaflow mufflers for some "turbo" whatever those are to quite it down a bit.

I have to ask.... How did that feel?? I paid less than that for 2 high flow Magna flow cats....... see www.dotcomparts.com 1995 Pathy MSD coil K&N air filter Amsoil 5W-30 Pacesetter Header Dual 2.25" Exhaust Magna Flow Highflow Cats Magnaflow Mufflers Search for Duals for pictures :tonguefinger:

I couldn't have said it better myself; though I don't think anyone is being tooooo critial just adding their two sense, which I like. I might be swapping in a 2-in 2-out Maganflow muffler to quite her down a couple dbs. Thanks for the support!!!!!!

When I get back from Seattle next week I'll do that. Thanks

LOL, if there is I'd never notice, the outside temp. in Bakersfield, CA has been over 100 F since before I arrived here in June.

LOL, looks, I'll dyno it and we'll have to compair it to the factory specs to see if it was all really about looks. Not that I care, in the end it was still cheaper than replacing the factory exhaust with OEM crap or something like it.

Yeah, I'll post some close ups next week when I drop the tranny for repairs/rebuild. System Set-up Pacesetter Headers 70-1197 armor coated and collectors flanged out to 2.25" $355 Magnaflow Cats Stainless 53004 Universal 3-way 2.25" x 2 $112 Magnaflow Tru X-Crossover Pipe 10790 Stainless 2.25" $72 Magnaflow Mufflers Stainless 4" x 9" Ovals 2.25 " 11365 $132 Aluminized Pipe and labor $650 Total $1321 Actual revs better throughout. Low end torque has increased noticeably which = better performance. It was definitely worth every penny. If you'll notice I had the tail-pipes terminated at the body line which I like compaired to some crappy chrome tip that I would've had to clean weekly. Also, the O2 sensor was installe at the x-pipe to measure accurate ratios.

LOL, 2.25" Pipes from headers back even had the collectors flanged out to 2.25" also.

Could be big help to me that's just a short dive and I've got nice little shop just north of seatle. Thanks for the heads up!

About a VG30DETT Swap......................Now that would be sexy!!!!!!!!!! :bow: There's been some posts on the 300ZX site I'm a member of; I thinking about doing this swap around the beginning of next year, in my 95 Pathy. So far the only issue I've read about is interference between the inter-cooler piping and the steering gear box. Not sure about the newer Pathys if they have a rack-in-pinion set up you might able to pull it off with out to much of a headache. Think about, look into then frick'n do it!!!! Sean

Hey, Just got my 1995 Pathy back in January it had the same "issue" here's how I "fixed"it. :idea: -Pull the third brake light out three plastic plates cover up three screws, remove them and push brake light assembly to the left it should pop out at that point may be to the right tho. If you don't have one or just pull the spray nozzle out. - Remove hose from sprayer and remove srcew attaching the sprayer to the brake light. (if required) -The easy way is to soak the sprayer peice in some type of detergent for a bit or if your careful like me you could use a little bit of brake or carb cleaner to breakdown the dirty that has cloged the sprayer. - After doing one or the other you can use a air compressor to blow the dirt out of the sprayer. - Did this and I have had no issues since even with negative temps in the Pullman area. Good luck! It not much fun but it works! :furious:

Sweet... ....My old stumping grounds I have to take the Pathy out the next through!!!!!!! How many of us are in and aroung the Grays Harbor area?????
