downpipes + no secondary cats, sound and some questions....
hello, i installed my vrsf downpipes 4 days ago and i have my secondary cats removed, my exhaust sounds really loud at 1500-1800 rpm then normal sound, i liked this sound in the beginning and now its annoying, anyone with catless downpipes and secondary cats removed has loud sound at 1500- 1800 rpm?
And my car is vibrating little bit at 800-1000rpm because downpipes are touching heat shield or whatever its called, mechanic that installed for me saying its aftermarket it can't be fixed it, should i go to another shop and reinstall it or adjust it.... |

Tell the mechanic that he has to re-adjust them. It's the shops fault they were't put in correctly, not your fault.
