Everyone seemed to recommend the center in/out resonator. I can easily get the offset, I thought that is was straight in/out.
The stock SVT catback resonator is offset in / out. Maybe hard to hook up center/center resonator but they flow better than offset...
I think adding the mufflers to stock is a good plan. I have the Bassani ($520) + 4" center/center premuffler ($80) & sounds great/nice power but for $650(total installed) it should. {{But can sell stock SVT exhaust for about $100 so net $550 investment.}} The extra money also buys you the nicer Bassani rear Y-split and much higher grade stainless but is worth an extra $200 over your Magnaflow system?? Probably not..
