Changed the rear section of my exhaust last week. I had a full dual custom before, but the rear had crush bend pipes. The new rear section is Stainless Steel Mandrel Bends and I now have two inlets into the stock mufflers. Have a look and listen.

Looks and sounds pretty good. Better than Joe-Z system IMO.

Ran new Dynos last week with my new rear and modified mufflers. The results are almost a year apart, so really can't compare, but a good baseline in my mind.

Blue - Stock Exhaust Manifolds and Cats, Modified custom dual exhaust with glass pack resonators, X pipe and stock mufflers, Takeda Intake

Red - As above with PPE Headers and Magnaflow HiFlow Cats

Green - As above with new mandrel bent rear section and dual inlets into stock mufflers

I'm happy with the results, although I was looking for at least 390HP Looks like the improvements come mostly at the top end.

I brought a friend up with me who also has an '08 F. He has PPE headers, no cats, a JoeZ exhaust and an Injen Intake. He had a run of 399+HP with smoothing set to 5. His other two runs were less spectacular because he was running lean and the electronics were retarding his timing.

Edit: To add new Graph for Friend's car compared to mine. He seems to be breathing better at the top end, above 5500 RPM.

Very nice, Lou! So your exhaust system is essentially stock quiet except for WOT and costs about 9whp. That's a worthwhile tradeoff.

^^^^Not quite, the only stock parts left in my exhaust system is the mufflers, and those are modified. Everything from the headers on back is non stock.

I meant as quiet as stock except WOT. When are we going to be able to order these from you?

Sounds great...subdued but still mean.

Well, I've got a friend in the business, so this was a science experiment that cost me nada.
