C250 quad exhaust with Rado downpipe!!

Just finished installing the Rado Downpipe. I had a muffler shop do a custom straight pipe with quad tips. I'm very satisfied with the sound and the performance. I plan on taking it to the dyno next week.



Rado downpipe right out of the box!

Trying to keep heat out of the engine bay. I built another turbo'd car and heat wrapping made a big difference in performance.
plus I like the way it looks.

Can we hear inside cabin (cruising) noise? Any annoying buzzing sound?

I really like the sound, sounds very nice for a C250, really!! However, cruising on it seems a bit buzzing to me, maybe just not my taste I really like the sound though.

The video was done real quick and is not the best quality. When I have time to post another I'll be sure to let you know.
You can definitely tell a difference in sound. My buddy wants to do a fly by clip so you can really hear it.

How would you say the performance difference is? Have been contemplating this mod for a while

After having it on I can feel a difference in the mid to high end RPMs. The power is definitely there when I really open it up. I have a dyno appointment next week and we'll see where the numbers are at.

Awesome can't wait to see some actual numbers! Not enough dyno runs done for anything performance oriented for these cars, will be interesting to see what you get

No Dyno numbers yet. Been really busy and currently out of town. The CEL did come on after 300 miles after the install. Going to have my buddy put a fouler on it and clear the code. I should be getting some numbers within the next week.

The build you have is what im going to be following up on, great work btw. I ordered the Rado dp for my car 2 days ago along with DEI heat wrap aswell. Got the dp for $300 brand spankin new, unopened free shipping on ebay out of sheer luck. My question is how difficult/long is the install on the dp? Also I know the car runs fine with the dp on stock tune, but does anyone know if the car will run rich/lean using the BMS JB+ tuner/intake with the dp?

I did the install myself in 2 hours. It was fairly easy. The heat wrap I am not to proud of. I noticed it shredding apart after a month. I did not hear soak before I applied because the instructions said I didn't need too. Thinking of redoing it and applying a silicone layer.
The car will be loud and you will smell exhaust. 😁. I'm trying to get it on a dyno but workin two jobs restricts my schedule.

I see, thanks for the quick response i've been trying to figure out how much the labor will cost me but I am considering doing it myself. And sorry for bumping not many people have these parts so its hard to find answers to questions like this.
