Well Guys/Gals I am mostly on Frenzy but thought everyone should see this since I know alot of Sedan are here as well...
Well after a long while with the midpipe being a 2.25 to 2.5 i decided to open it up a bit.
Exhaust as follows:
Top Speed Pro 1 Headers (Heat Wrapped)
Top Speed Pro 1 Y-Pipe 2.25 to 3 inch
Custom 3 Inch Crush Bend with an Extreme Technologies Racing Muffler (NHRA Approved)
HKS Legamax Muffler
The HKS has a 3 inch flange and it reduces to 2.5 smoothly.
You can notice in the pics the mid pipe looks immensely bigger than the HKS, yet incredibly enough NO RASP!
Car lost torque down low but i can feel the transition up top, pulls much nicer, rev's a bit quicker since the restriction is not as bad as it was.
Noise level in the cabin is about moderate, with the radio 12-14 you can not hear the exhaust only the intake.
I am awaiting the Crawford Z HFC's and I will revise this thread once its done.... as usual dyno's are pending!
For now here is a video clip.
and some pics
