joehurdler Posted August 24, 2004 Share Posted August 24, 2004 Hi there everyone. I'm pretty new to all this and was wondering if anyone had any suggestions for a good intake and exhaust for a 2003 Pathfinder? Thanks, Joe Link to comment Share on other sites More sharing options...
jrvanas Posted August 25, 2004 Share Posted August 25, 2004 Well, As you know there is not much on the market for aftermakerket products for a pathy. I have an '01 pathy and I should have the below intake by this coming Friday and hopefully installed the same night after I get outta work...its the same model from '01 to '03. Air Intake As far as a exhaust -> I am open to suggestions bc that is my next step. ~jrvanas Link to comment Share on other sites More sharing options...
jrvanas Posted August 29, 2004 Share Posted August 29, 2004 Here mine is - got the intake on Friday - installed Saturday morning. Not too hard to intall - took about 1 hour. The only thing wrong with this kit is that there is a resinator I wished to keep - that mean I will have to drill some holes in the housing to attach the resinator - currently it is sitting there with velcro and a bungee cord.

vengeful Posted August 29, 2004 Share Posted August 29, 2004 I have a 99 with the 3.3 (so, different motor, but yeah). I have the JWT Pop-Charger intake and it went it very easily. I have a custom Flowmaster exhaust. Used a delta-flow 40-series Flowmaster muffler I bought on eBay and had an exhaust shop fabricate pipes to my specs. Works very well, sounds incredible and I get a very noticible increase in performance. Link to comment Share on other sites More sharing options...
jrvanas Posted August 30, 2004 Share Posted August 30, 2004 Hey Venge, Do you happen to have a sound clip of your exhaust. I'm trying to decide on one...we have a custom exhaust shop here. Not sure if he just fabricates or makes from scratch - guess I should stop by. Just looked - there is no web site but here are his brands... Brands: magnaflow, flowmaster, bullet, remus ~jrvanas Link to comment Share on other sites More sharing options...
jrvanas Posted August 31, 2004 Share Posted August 31, 2004 Looks like my intake is getting me better milage too - I just averaged about 20MPG running about 50/50 city/highway. The 4% increase they state looks very promising. ~jrvanas Link to comment Share on other sites More sharing options...
Guest Blazing Red Posted September 2, 2004 Share Posted September 2, 2004 I have a 2000SE and I installed a Magnaflow last fall. Ran the thing for about a month, but the decibels inside the cabin were to loud. Went and bought a Magnaflow resonator to cool down the interior noise. Oh ya, we increased the back pipes by a 1/2 inch and I have added stainless steel tip (welded on) coming straight out the back versus the OEM side discharge. The sound is beautiful, nice lil rumble to it. I live in the mountains outside Denver, and my 'seat of the butt dyno' definitely notices an increase in power. I really notice not having to tromp down anymore on the accelator to get up the mountain roads. As far as intake, I searched and searched, and didn't see anything that looked half decent for installing. So, I examed the oem thoroughly and decided to drill 1" holes in a row in the plastic intake box, just below the filter (K&N Filter that is). Now I'm working on getting a direct flow from just behind the grill to these holes - don't want to suck any of that hot hot engine air in! Have any you folks installed performance plug wires ?

jrvanas Posted September 2, 2004 Share Posted September 2, 2004 Nice reply man, I have not installed wires, I think my next tasks are exhaust and tires before winter. After that I might shoot for some plugs, but I'm pushing about 245hp to the wheels with my intake, not sure if I need too much more for a SUV, not like im going to 1/4 mile this thing - heehee. ~jrvanas Link to comment Share on other sites More sharing options...
big_johnson Posted September 2, 2004 Share Posted September 2, 2004 245 to the wheels? I think not. Stock 3.5 pathy is 240 @ the crank, factor in ~20% drivetrain loss, that equates to 192 at the wheels. So according to your calculations, with 245 @ the wheels, you are pushing 306hp at the crank, an increase of 66 crank hp with an intake? Once again, I think not Link to comment Share on other sites More sharing options...
jrvanas Posted September 2, 2004 Share Posted September 2, 2004 Sowwie, I meant 245 to the crank - but for some reason I was thinking to the wheels. Thanks for clarifing for me! :contract: ~jrvanas Link to comment Share on other sites More sharing options...
