Remap Query - To Cat Or Not?

[Doggy]

The 216 twin cam was an awesome car....

Well, she wanted a small hatchback with power steering.
Amazingly, she never discovered what happened north of 5000 revs.

I recently drove a 216 to the scrapyard for a 'mate' and I was having so much fun that I changed my mind and just hacked around in it for a week first....!
Pulled like a train, just kept pulling and wanting to go faster - made me smile lots ( 92mph in 3rd.... )
Sadly the gear linkage went, which on those was inside the gearbox. As the car only cost £70 and he had it for 2 years it wasn't worth the repair. The later models just went ' bang ' over 5,000 revs...

That guide isn't what you want to do, I purchased the exact car that had that fitted and after a couple of months did the proper decat with a bit of straight pipe in to replace the cat. Saw good gains over just the empty cat. But bear in mind the car was running 165BHP at the time, so I'd have seen a greater gain.

The best thing in my opinion would be a straight pipe like the picture, then cut the cat open, wrap it around the pipe and weld it back together, so you have the MOT-safe look of a cat without the airflow interference of a cavern

Well, I'm not too worried about that, my MOT tester said he'll pass my new homebrew exhaust (3"straight through to a cherrybomb backbox). It's all legal etc, he's just "sympathetic", same as most local independents if you're not an arse to them.

Cherry Bomb FTW! I haven't seen one of those since about 1987 - I didn't know you could still get them.

Do you know how the system sounds yet? you will hear the turbo for sure and then diesels make a very low, gruff sound.

Here's my first run at prescott this summer, best with headphones
