I have a el xr6.
Pacemaker extractors and 2.5 exhaust.
I wanna take out the resistance that the cat gives me.

My idea is to weld up a 2.5 pipe to the same length as cat with flanges, then put the heat shroud over the pipe off the cat to make look like the cat is really there.

Can anyone help me to weld up this?
Exhaust shops dont wanna do it coz they might have to break a sweat.

Exhaust shops dont wanna do it because they are in the poo if you get caught.

Do your bit for the environment and keep the cat. If it's bothering you that much, splash out on a bigger one.

It's our responsibility, as car owners, to protect our environment as much as we can. The guys at the exhaust shops are just doing their bit.

It's worth getting a better cat IMO. You'll be luck to find somebody to tell you different on a public forum anyway

well i guess hes lucky then. if u really want to do this than dont bother welding up anything fancy, just take off the heat shroud, cut a hole in the top of the cat, empty out all the crap inside the cat, then weld on the heat sheild and weld the hollow cat back on to the muffler system.

Now the cops are tracking you down, they will knock on your door in the morning and take the car for EPA testing

Hehe.....its amazing what a dougnut and a coffee will do to change his mind though

Hehe good one mate
The other way is to tell them there's a doughnut sale on at Coles

A good high flow cat will acctually improve your system.

Or if you still want a gutted cat i have a 3" one sitting in the shed with flanges on it, and a pipe welded in the guts.

SVO I got a secret but u bag JMM so much......

Nah Hollow out your original cat with a 2.5" pipe driven down the centre
Try to keep as much honey comb in the original Cat when putting the pipe down its guts so the ceramic still heats up but the restriction is totally passed through your new pipe down the guts. The Honeycomb will still heat up so if coppers wave there heat wand under your car your cat still has temperature
