Need to derestrict baffle. Cut thicker tube to same as short that goes through rubber bushings. Lock tight all bolts or double nut. Too much play in swivel header. Maybe brad or wrap. Other than that seems thin but we will see.

Re: Doppler street cup
What’s restricting the baffle Charlie?
Re: Doppler street cup
They work real well on Moby's, little big for 103's but I really like them so far
Re: Doppler street cup
Once the baffle is removed and the silencer wraps are off there are two tack welds that have to be dremeled off of the tip then discard the restrictor tube reassemble and rewrap. helpful French videos on youtube! Also the performance has a lot to do with the variator weights N'est ce pas!

Post some pics of the removal!
Re: Doppler street cup
It’s a big pipe. I derestricted it. I have a 70cc airsal and had a 15mm sha. I couldn't wake that pipe up very well no matter how I weighted the variator(er3).
I went to larger carb (21mm phbg) and did the engine spring mod. The bike is super responsive now.
Re: Doppler street cup
Initially I only removed the header restriction. The baffle restriction blew out somehow after about 50 miles. Didnt really seem to make a difference before or after. V fast pipe tho.
The swivel gets all 2 stroke exhaust gooped up pretty quick and stiffens up. At least in my experience

I was REALLY impressed with this pipe on the AV7, I think it really paired well with the torquey nature of the av7 compared to the av10 or 103

Re: Doppler street cup
Av7 74cc airsal Doppler er3 4 heavy weights. 15 sha. Weights about right-need less. 11/48. Still tops out about 45 nicely.
