I didn't think you guys living in the British Channel Islands even had catalytic converters. Your explanation sounds a bit silly.

How so? If I'm wrong, please correct me.

A gutted cat creates a significant amount of turbulence in the exhaust flow. Turbulence is far worse than the "restrictive" part of the cat (I put it in quotes because our cats are actually quite free flowing). The turbulence created will probably make you feel like you have power down low, it'll choke up high, and eventully reversion will occur. Reversion is when the exhaust gas is pushed back into the combustion chambers, contaminating the intake charge, and causing a serious loss of power.

A4 manifold was a good idea. Gutting the cat was not.

thats true i actually replaced my cat with a cherrybomb (life long goal met) and it gave me (estimated) 10 alone from the back pressure of the cherrybomb idk proly a few from the cat too.

Seriously? Sweet!

I wish our cars responded as well to simple mods as those old domestic designs. Those designs had such weird restrictions that opening them up created a ton of gains. Our cars are built to very efficient and tight tolerances. Our biggest bottleneck, aside from the usual breathing parts, would be the exhaust ports. Open those up, and gains can be seen... If only something gave us an easy 20whp!

20whp? I have a hard time believing that. I flipped the lid on my old 88' K1500, which has the TBI 350. Couldn't tell a difference other than noise. I ended up flipping it back.

dyno proven man. i'm not sure how to explain this . . . basically, you're more likely to feel a 20hp gain on a car that started with 100hp as opposed to a car that started off with 200. and it wasnt a full 20hp. 17-19hp but still.

If he knows something I don't, then I honestly want to know where I'm wrong. I'd rather not give incorrect information, if that's what I'm doing.

However, he has failed to reply, and I have done my research... so all I can do is assume that I'm correct.

There may be other factors at play, true. Of course, every engine is different, so while that one may have gained 20whp, there is a very possible chance that mine gained far less. We all know how consistent chevy's small block castings are, after all...
