I'm looking at replacing the rear cats and h-pipe with a X-pipe. Anyone have any idea what size the x-pipe should be? Leaning toward the Magnaflow one.

Thanks to everyone and enjoy the New Year.

n/a should be 2.25" srt i believe is 2.5"

And just a side note bought mine a week ago and my shop said he cant do it because hes not allowed to take out cats. But i cut them out and he helped me out And btw i got one for 30$ on ebay, no need to spend 100$ on the same piece of stamped metal.

 

Another side note, I removed the rear cats when my car was a high mileage NA and it still passed the emission testing here in Ontario
Even with the V8 it still passes with one set of cats installed

 

who'd you pay-off and how much?

 

It's a 2.25 like stated previously, but upgrade it to a 2.5 for my flow. That's what I did

 

Where did you have it installed? Any pic?

 

I didn't do an X Pipe, but I did a custom catback exhaust setup. The concept is essentially the same though. They took out the 2.25 inch pipe, replaced it with a 2.5 inch pipe for more flow. Then I chose a flowmaster super 44 muffler for the sound, and c4 corvette exhaust tips for looks. A place in the town over from me did the job. With labor and all the parts I told you about the total cost came out to be $250. Probably the best mod I have ever done to a car. Here is my video of how it sounded the day after I got it done

 

Here is the 2½" magnaflow X installed where the rear cats on a limited use to be.

 

Well, mine is going onto the SRT6. Is the X pipe the same size as the one for the N/A? I know many people have done it. I've deleted the muffler and want a little more flow and "Throat" without the drone so the resonator will stay for now. No inspections in FL so WEEE!

 

Hey is this a bolt-in mod? If so how much does the bolt-in cost that would remove the rear cats and have the X crossover? This looks like a cool HP or 2 mod. Oh, Most important, what does it sound like? I don't want anything obnoxiously loud! The tune/intake mods throatier sound is much cool and I don't want to change it that much! Any help you can provide in these points would be (in my case at least) greatly appreciated!

 

Probably could be a clamp on mod but I would not recommend it. If you were local to me I would do all the work needed for duals all the way back in exchange for the 2 removed used cats.

Someone has posted what the car sounds like with the rear cats removed but kept the factory muffler. Sounded pretty good if I remember correctly. Just have to find it in an old thread...

 

I cannot tell you how fast I looked up to see where you are located, only to just shrink back into my seat. I think a mod like this would free some back pressure and also make her sound just a little more menacing. Too bad I couldn't take you up on this offer. I also am a fan of true dual exhausts (one pipe from each header back to exhaust) and having a crossover pipe (prefer X crossover) enhances exhaust flow and reduces back pressure.

 

Can anyone point me to the correct P/N for the Magnaflow "X" that is the right size for the SRT6?
