Hi,

I am about to install a complete new exhaust system on my 1997 Camaro Z28 5.7L V8. I think I will buy the Hooker Super Competition Long Tube headers from thunderracing.com. The system from the headers and back will be custom made in 3" S/S. Will I gain any power if I remove the cats? Will I have any problems relating to the car/electronics and not thinking about emissions?

How many mufflers will I have to add? Is one in the back enough or will it be too loudly?

Thanks

If you are running long tubes, then you are going to have to run an off-road y-pipe of some sort. Once you get that y-pipe installed, you will see how much of a chore it is to add a pair of cats. If you can get away with not having them, then I would. If not, it can be done though. One muffler is more then adequate to keep your exhaust to a tame level. Heck, people cannot even tell I am running long tube headers because of the Magnaflow catback I am running.

 

Okay - should I buy the JBA Cat-Forward header system including the y-pipe for dual cats in stead - what are the pros and cons re. the long tube headers and the JBA system?

Thanks

 

i just picked up my car from the shop its noticeably louder and gets insane at WOT but sounds just like a magnaflow catback at lower gas positions, i had the shop build me a custom 3" exhaust with a magnaflow muffler/tips just alittle bit more tingy and cleaner sounding (no popping just pure muscle sounding vibrations) im so happy with the sound and performance
