Which X-Pipe is best to decrease popping on deceleration? (NXT Step Exhaust)

Hello,

I have the NXT Step exhaust on my 04 Coupe and I love it. I want to further perfect it with an xpipe to reduce the popping on decel. Which X-Pipe best accomplishes this? I've seen generic ones, borla, bassani, etc.

Thanks

I'd say that about any x-pipe will do the job.

tuning will reduce decel pop more than x-pipe - but here is what I had done - custom X- between header collector and cats

i did a lot of research on this subject and decided on the corsa. the whole theory around the x-pipe is to balance the pressures between the pipes. for that, you dont need the flow to intersect, you just need to have them connected at one point. maybe this thread will help you. read post #10 http://forums.corvetteforum.com/c5-t...ch-x-pipe.html.

I think any X pipe will help.
I went with Corsa and am very satisfied with the sound............

X-pipes will only do so much. You already have an H-pipe.

To be clear, decel popping indicates a leaner condition, so to make it disappear, you'd have to richen the mixture which decreases performance and fuel economy.

I take it you have a custom tune.
