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...

lol very true, typical american rubbish..like they know whats any good for the world, do they think about pollution when they start blowing everything up with missiles and bombs...no lol

      Hey. Very valuable information about pitwork, I will pay attention when buying any consumable parts 🙏 As for the carpets - I got a handful of information from nengun, from which it appears that indeed the carpets for the driver's side are OEM. They are not able to show me any pictures due to the long chain of different sales entities but after I place the order, as soon as the goods arrive at the nengun warehouse from which they will send the shipment to me they can send me photos and if my purchase differs from OEM I can immediately return it / cancel the purchase. I think I will give it a try 😉. Of course i'll let you know what's what as soon as i get them P.s. I know the topic is not relevant to the thread, but both nengun and amayama have these SICK 😍 trunk room lamps available. Do you know anyone who ordered them? I need to have one in my car
