I might get flamed, but it might work
Would I see some good gains if I mounted a remote controled "straight pipes" valve where the cat would go. Let me explain, have a buterfly valve (or something similar) welded to a straight pipe where the cat converter would go. Basically with the valve closed it would be like running a straight tube to the muffler where the cat would be, but when the valve is open, there would be a short tube that would run out and point towards the ground that the exaust could travel through. Granted it would be loud. Would I lose tons of low end torque? Would I even see great results on the top end? It just seems much cheaper (and possibly more effective) than a full system. There would be an after market y-pipe installed.

So, basically my questions, would this give benifits with a n/a engine not on nitrous, how about on nitrous?
Just curious.

 

About 5 HP NA and a few more boosted. They have manual and electronic cutouts that do that same thing.

I bet it will get the best results boosted and using headers!

 

Cool, where can I find the electric cutouts. (I will do a search) But it seems like it would be an interesting project to do on my own.
Thanks for the reply!

I got 6hp and 2 tq with no loss. This on headers with tons of other mods though, mildly modded N/A might respond differently.

 

That is exactally what I was thinking. But I bet I could build it for less than $200

JC witney has one also on a cable for cheap, but the cheaper ones may leak.
