HElix catted DP V3 versus V2 ?
Just wondering if anyone has any feedback on advantages disadvantages of the Helix V2 vs V3 DP with catyltic converter. I read one forum on new V3 with theme being more difficult to install V3.
Any info on differences on performance/safety ect. I am currently looking into buying used (4000 mi) helix V2, and was wondering if what was better idea to buy new V3. thanks for any feedback.
