New Exhaust OBX RACING

[Rigaud]

Hi Greg, thanks for the info!

I installed my OBX exhaust line last night with a Magnaflow Cat and resonator. I cut the resonator shorter to fit, the one I had was too long. All rewelded like the way it was purchased. My header, a 4-1 of low quality (better then stock manifold) was missing the bung for the sensor, another item to drill a hole for and mig weld. Got it all done and I was pleasantly surprised with the front to rear line. No drumming at all or resonance through the floor. Nice deep sound up to 2500 - 2700 but higher then that and it's too loud for street driving. Gonna pick up some medium and fine stainless steel wool and cut open the muffler. Might redirect the internals depending how it flows too.

As for the 1ZZ TB, that went well and I really don't understand why people use a union to bypass the coolant lines. One of the hoses is placed just right and long enough to simply cancel one hose and use the other to connect in a loop. Voila.......solved. Removed the epoxy on the idle setscrew but haven't turned it yet. I did the chip swap while everything was plugged in. Drilled the rivets, swapped and new rivets. I messed up my intake tube so I made the stock tube and airbox fit, no issues with anything at all. That's temporary till I get it done right with my K7N cone filter.

Sorry Greg, I saw your response after I did it. I have a 2700 rpm cold start up and it lasts 20-30 secs and goes down but warm idle is at around 1000rpm. I'll adjust the idle with the engine and ignition off. Proper idle will solve that high idle Code I got, settle it at around 750rpm. Now I need to get a quicker response, anything I can do or add (module) to rectify the response time?

Cheers
John
