Quiet outside! Still TOO Much Drooning and Resonance inside between 2,700 and 3,300 Rpms for my wife and I do not care for it either! I just bought a Glass Pack from Summit Racing Part number SUM -630805 for $21.05 It is 18 inches long with 2.50 Inlet and outlet with a 2.50 inch core. I am hoping that thus us a Louvered Core to take out more noise than the Straight through drilled tubing of the Magnaflow. From the outside the Magna Flow looks and sounds great! I just cannot get rid of this last noise problem!
If this does not work, then I will get a Flo-Pro Glass Pack Muffler that has a 15 inch body and is 20 inches long (overall) that has a 2.25 core with spiral louvers and weld the 2.50 inlet and outlet Stainless ends on it from the remaining center tube from the original system!
I know reducing the internal size will reduce the noise but at what cost in performance?
Will the exhaust temp increase too much?
All I know at this point is I still have 2 more tries to get this right inside before I run out of Options.
The good news is, I am still ahead of the game Cost wise. Spent $539 Delivered for the full MagnaFlow system for the 03 MCS
and $63 for the 4th Magna Flow Resonator and $15 for the welding, Add to that $31 delivered for the Summit Racing Glass Pack and I am at $649 total! Still under the average price for the entire system and the BETTER News is, the car is running like a Scalded Rabbit! Even with Traction ON, the tires are trying to spin up all of the way to redline in 1st and second Gear and some what scary to drive with WOT in any gear!.
SO Far I love how it looks on and under the car! I Love the performance and I like the sound "Outside" the car with the 2nd Resonator on the car! I sure would not buy one without the second Resonator because in and out it is waay too loud! My Hope is that before I have spent $700 USD I get this right and we all can live happy. "Anyone here have a DINAN Exhaust on their car? A friend of mine is looking into that 1 muffler special. Is it as loud as a Borla or other system?
