How much HP gain with no cats?

[Early93Viper]

How much would one gain (estimated HP) taking the cats off his/her stock GEN I Viper?

 

[plumcrazy]

sean roe told me about 18RWHP if going to a HF cat

On a 93, no cat, I would guess 20-25

Wow............not bad. Can anyone confirm this?

I can, my dyno #'s picked up after I added HF cats.

Sure, I have 410HP without cats. Gen1's usually get about 370-390 area as stock.

I have a 96 RT/10 (gen I with rear exit exhaust) with a modular exhaust system. I can bolt all my components from the heads to the tail pipes in or out at will. (helps with momentary emissions testing). My car consistently has shown a 7-9 rwhp differential.

Thanks

take a look through a stock exhaust system on a gen.1,,,, Has to be at least worth 10-15 h.p. to remove cats and use straight through muffs.

Here you go. A modular system with 3 bolt flanges.

If you go to my media section you can also find some mpegs to hear the roar of the beast. It's intense...

Media section? I can only go to Images the other link won't work.
