X pipe Question

Hello,

I would like to do an x pipe that keeps the primary cats on so I dont void warrenty and dont get a cell. I have an a custom exhaust setup with two electronically controlled cut outs that exit right before the muffiler. I have two questions.


1. Can I get an X pipe and still keep these?
2. What are the effects on volume when using an x pipe and stock exhaust?


Thanks,
Josh

You won't really void any warranty by messing with your exhaust setup and getting a CEL.


As far as adding an x-pipe to stock muffler, under load and WOT it is much louder than stock, but when cruising i'd say there's almost no difference in added volume (which is great) also no added drone.

+1 to what Mr Harris said. Much louder under load but could still keep the noise down under cruising speed.

Yes, it is possible to retain your primary cats and retain your cutouts which are welded to your connecting pipes.

You have a few options you can take: Challenge street x-pipe, the custom route, meisterchaft lx pipe, or fabspeed.

Thanks for your input. Now I just need to find one of these used. The search begins!

Yep, basically what everyone is saying.

If you want to keep your primary cats, you WILL need to cut your OEM pipe after the stock cats as they are all connected. There are several Xpipe manufacturers that will work for you. Remember, you also have the option of high flow cats (Gintani, Fabspeed, etc).

As for the sound, the Xpipe will make a significant difference under load. It's actually very loud even when you're going slow. Exiting my development when the car is still cold is VERY loud and sometimes I get a bit self conscious. The concept of "drone" is very subjective. Some think the OEM system has drone, some do not. I do have an Agency Power rear end that was very quiet and did not drone. With my Fabspeed resonated Xpipe, it did drone a little, but it's not bothersome at all.
