- Ve SV6 2011
I recently installed a x-force 2.5 inch catback on my 2011 SV6, after finding a really good deal on gumtree. The exhaust works perfectly and sounds great until i downshift into second gear. If i dont rev-match when dropping into second, the car violently vibrations underneath me. When i had the stock exhaust it would be completely fine. I recently got a new clutch installed so i dont think it is a clutch issue. This also only occurs when i down shift into second at a mid to high rpm, at lower rpm such as under 2000 it shakes much less. It also occasionally happens at third but it is much less violent.
If anyone has any advice or knows how to fix this, it would be greatly appreciated
