Any Challenge Exhaust reviews?

[BIGW0RM]

Before I get blasted.... I did search TITLES for anything "challenge". I did not see any reviews. Only videos.

That said, I am interested in this exhaust, but wanted to know if it drones? I think it sounds awesome but the videos Ive seen show it mated with an aftermarket x pipe.

Does anyone on this forum have the exhaust mated with the stock X pipe? Any drone issues?

Or does anyone have it with the challenge x pipe that allows you to use your stock CATs?


Any reviews of said exhaust would be appreciated.


Thanks!

One local member has been running the rear only on his E90 for the past 2-3 mos or so. He said he didnt notice any drone at cruising speeds and daily drives his car in mixed hwy/street commute. He has had a number of passengers give him the same feedback. We are hoping to do some videos in the next 2-3 days of the rear section only as long as weather allows here. If it works out, we'll have decibel ratings for the rear section as well at the same time.

You likely wont yet find any reviews as this system was just offered on the market this week. But We'll ask any that pick one up to report back. Another local guy is supposed to get one soon as well.

Here is a new video from today with the Challenge Rear Section Exhaust with stock X pipe.

I also recorded decibel readings for numerous situations. If we are able to get our hands on a stock M3 this week, ill get some stock baseline levels for you. All of the levels are very reasonable on this exhaust

All db readings were done at the industry/legal standard outside of the car:

Outside

4,000 RPM: 84db
5,500 RPM: 87db
7,000 RPM: 91db


In car

30 MPH Cruising: 53db
65 MPH Cruising: 68db
75 MPH Cruising: 71db
Full throttle 0-60: 71db max

Sounds very tame. I think I heard a whistle tip too? Seriously... Not a Bub rub whistle either. I heard it twice too!

Looks great, but I think it's way to quiet for my taste. Thanks for posting.

The goal was to make a nice sounding exhaust with no drone which is no easy task. I think it sounds best with the full exhaust myself . Its just the equipment on the higher pitch sound. The internal mic on the cam so it can get blown out pretty easy unfortunately. The second clip with a higher model camera didnt record the same noise. We have a few other clips with the same camera

^-- I think it sounds awesome, I will be putting in an order very soon.

[BIGW0RM]

what is that sound at 43 seconds? And 46 seconds?

[M3Monster]

i only hear the first whistle, sounds like the brake releasing. Like the hill assist.

So at wot it's pretty loud no? Sounds amazing though.

I have the Street X-pipe with the Rear section. Had it for a about 6 months now. Very happy with the sound and also the build quality. It is on the quiet side when just plugging around town, which to be honest is a good thing. Most people think they want this loud nasty exhaust until they have to live with it day to day (my opinion anyway). If you're still thinking about it and want me to pass on any more info, just let me know. Nice exhaust, specially for the price.
