Is there a way to quiet this down a lot? I have the mhp longtube headers with castles mids and it's retarded loud. I'm actually thinking I may remove them and put the stock system back on and sell these.

It's easy, buy some 200 cell sports cats for a start. Then add an x pipe and then replace the stock resonators with a larger diameter resonators from any muffler shop. That will fix it for you without sacrificingmuch if any power. Longtube headers without cats is just lunacy for a daily driver! Goodluck

I just put on a set of 100 cell cats from random tech, I got some Vbands so i can remove them for the track and yes they made a huge impact on the noise. just an FYI today she pulled a 489 rwhp with them on.....

IMO, start with an X-pipe.

MHP has LTH silencers. Might wanna look into these.
