That is one short system you had/have. man, just imagine if you duplicate that very same system with thin wall 304 or 321 stainless like I had.
If those were the regular 2-4 chamber Flowmasters you would have had an additional 5-8 Lbs. Your advantage is the turn downs before the rear end thus cutting off all that additional tail pipe weight. With all that is going on with me lately, I have not had a chance to get to my car till just today. I installed the new Titanium shackles and rear spring shock plates on one side only. Looks good and I'll have flicks sometime this week if I get the other side finished I hope. I do not look forward to cutting this stuff though it is good card exercise.LOL.
