I am planning to machine a piece of stainless to sit inside the cat perfectly then weld in. finishing buy smothing off with a die grinder.

I guess it would be what you call a really high flowing cat :P

Spend a few hundred now and get a decent cat, or pay $10,000 later on for punching the cat out, i know which one i'd be doing.

qft.

Get a good exhaust shop to make you up an exhaust from turbo back, better still get one to make one from cylinder head back - they will want to know things like cam timing and turbo specifics, and it will probably cost a fair whack - But you'll have the best performance you are going to get on the street.

Also remember how people think. If you're driving around a show pony that just screams "book me" (or "race me" - they are the same thing) you are always going to get more hassles from your local law enforcement department.

You can have a performance exhaust with a cat, you just have to go about it the right way - like most things in life.

I would suggest that all of you who have or planning to punch out your cat go to the movies and see "An Inconvenient Truth" starring Al Gore. Or at least watch the trailer on yahoo or something. Freaking stirring stuff. It took a movie for me to actually stand up and give a shit about global warming...

Am i gonna join greenpeace or joing amnesty international or something? Hell No. But I will do my part to help prolong the life of this small planet.

"An Inconvenient Truth" = typical propaganda

lets leave that alone...

as for cat punching, well i had a 2.5" gutted on my car and changed to a 3" high-flow and noticed no difference in power

i even have the gutted 2.5" cat sitting my garage (in brisbane) if anyone wants to take it off my hands for $25 :P

Unless ur runnin big power a 3" high flow will do fine IMO. i have a pipe runnin through my cat on mine, and it was noticibly different from changing, still has the 02 sensor on the top so it looks like its still a cat...

the sound is mad, and either way getting attention from the cops from that sound is the last thing i gotta worry about since it happens as soon as they see the car, let alone hear it or even see under hood...

      If you have a Nissan from Japan and model year is from 2016 to 2024, just say you have an Infiniti Q50 4 doors... Why are telling you have an import?

      Rb25det s1 igniter pin out

      By GTSBoy · Posted

      It's definitely not firing order. But I think it should also be made clear that the output that gets fired is the one that corresponds to the input that was switched at the ECU. So you could scramble them up totally so that the numbers meant nothing, and so long as you had the inputs and outputs matched up, you'd be fine. The reason I make that point is that blanket statements about what it is supposed to be don't always hold out in a world where there's been 30 years for the wiring to have been stuffed with.

      Hello, im asking about this guy - coil igniter on rb25det series 1 r33 s1 engine. I need to know if pins on coil side indicate coils itself from 1-6 or it’s firing order so pin nr1 goes to 1st fired spark plug:(1pin-1firing spark, 2pin-5order firing spark, 3-3, 4-6, 5-2, 6-4…)   photo: https://files.fm/f/k9pdug38uq

      Powder coat on mating surface

      By GTSBoy · Posted

      Remove it. Certainly from the hub face. I'm not in love with leaving it on the wheel assembly surface either - but if it is common to do so, then....maybe fair enough. It's not difficult. Just time consuming. For the hub face you just need a large enough block and suitable grades of abrasive paper to get it off flat. The same would be true of the assembly face. Just more time consuming, probably needing a lot more care. It's defo going to be easier just to assemble the wheels as is, seal them up, and check them periodically to see if there's any movement or loosening of the fasteners, than it will be to remove it though.

      Powder coat on mating surface

      By dyl33 · Posted

      Hello, I got my wheels powder coated and they've powder coated bloody everything the mating surface and hub (even told them not to lol) anyway should I leave it or remove it. (Would be very hard) I've searched a lot and lots of powder coaters don't mask the mating surface but do mask the hub surface. How bad it powder coat on the mating surface or hub? My question is what should I do?
