Challenge Catted DP installed-Video-

Got a nice deal on a new unused challenge Downpipe and I just installed it today.

I didn't wanna get a catless due to the smell. So
Far the sound with my modified muffler is fantastic. No smell as well. I can also report that the throttle response has improved a lot. Also the overrun is very crisp now and the backfires are constant . You can hear the turbo spool up now as well. It's pretty loud with my modded muffler I wouldn't ever want anything louder then this it would get annoying.

Enjoy. I'll get some drive by videos this weekend and some exterior driving videos as well.

Thanks. I love the sound.
When I put the challenge side by side of the OEM I was nervous cuz the challenge pipe is actually longer. But it fits beautiful. The finish on it is quite nice, we'll see how it holds up, I read somewhere that one member had the converter cell fall apart inside in his challenge pipes.

No CEL after 100 miles, but my JB4 will be delivered by Saturday so I'll have it in and should be running with map 2.

Dude, I did 1000 miles and never got a CEL on that DP. I got JB4 now on Map 2, you're going to love the loud burbles.

Nice! I like hearing that no CEL! Glad it's holding up. Challange makes a quality piece for sure.

So it burbles even more with JB4 Map 2?
