I just bought 05 r/t. I understand the benefits of the cat back everyone talks about. But, has anyone tried the full system, headers, mid-pipes, and cat back. If the cat backs are good, wouldn't this be that much better?

Let this beginner know what you think.

 

i have a full exhaust. there is surelymore to be gained by adding headers and high flow cats to the system.

 

Did you have it done all at once? If not, was there a big difference to each stage?

 

i did it in stages. started with a flowmaster catback system. there was only a few systems out at the time and flowmaster was the only one using 2 1/2" tubing. all others were using 2 1/4" tubing. there were no headers or midpipes available yet. next i installed JBA headers as soon as they were released. finally, i added the JBA mid pipes with hiflo catsonce they were available.

no noticable gains on the catback, nice gain with the headers, and a big gain with the hi-flo cats. once all the restrictions were gone, the gains were huge. it seems like the biggest restriction was in the mid pipe and cats.
