Magnaflow Exhaust Question

[joward]

Hey guys, I was wondering if I could get some help with this problem here, keep in mind i drive a 2008 Lincoln MKZ and not an actual fusion sport. However these cars are almost identical as far as engine and exhaust setup goes. About 6 months ago I got Magnaflow #11225 mufflers and had the shops fill in the blanks. By fill in the blanks I mean they welded the stock tips back on and did a second resonator delete. The exhaust sounds good but I feel like it is too quiet in the high RPM range (above 3000), just a little bit louder than stock. However, in the lower ranges its just right (almost a little loud) much louder than stock. I realized that in welding the stock tips on, the pipe diameter after the muffler outlet just before the tip went from 2.25"(muffler outlet diameter) back to a 2.00" (the stock pipe diameter) then out through the 3" stock tip. I was just wondering if I increased that pipe size, after the muffler but before the tip and put new tips on with an inlet of 2.25" instead of the stock tips which have an inlet of 2.00", would it help with my problem. Would it make the low RPMs louder and not do anything for the high RPMs? Or the other way around? Or make both louder? If you guys think it wouldn't be worth the money then let me know that too! Any input would be great.

 

Thanks in advance!
