extending duals under-axle
extending duals under-axle I intend to get this process done soon, seeing as how my county will not allow me to pass an inspection anymore and how i just don't like smelling gas 24/7.
Just for peace of mind,
If i put 2 high flow cats on my TSP duals, will it muffle the sound significantly?
Around how much HP will i lose?(rough estimate)
And how much do you think it will cost? (Welding 2 cats after cutting pipe, extend the piping under the axle out to the rear)
also, what tips do you guys recommend?

I have dual tips from my SLP dual/dual stock firehawk exhaust, will those work? i'm not sure how big the inlet is for the tips if they were to cut them off... i like those tips a lot though, btw in your video mvette, did you have cats on?
No don't have any cats. A muffler shop should be able to expand them enough to slip over the tailpipes. May be kinda thin after they expand them but I would think they could do it. Just have to ask them

I had cats installed on my TSP duals when I had my 99 Z28 (I think it cost like $75 + cost of the cats) and didn't like it at all. It took away some of the deep throaty sound of it. If I was you, I would have them ran out the back and see how you like the sound with it like that, and if you still want it quieter get the cats put on. Running mine out the back gave it a more "refined" tone but still has the deep sound to it.
i extended mine and i don't smell gas anymore and it did quiet it down since it's not bouncing off the ground, but i'm not runnin cats just 2 1/2 into LM1 bullets and 3" out the back
Really the only true reason i want cats is to pass inspection, i seem to have trouble here in midland i failed and my vin number was entered into a computer... ******* thing is, i didnt tell him to inspect my car when i took it there, i was having my tires balanced... next second i see him crawling to the computer and handing me a failed inspection. So i can't take it anywhere local that is on the same network as the state. Anyone in Midland or near midland/odessa know where to get one. I'm moving to Denton /DFW soon, so that's a possibility too
