Owner reviews for muffler

I upgraded the muffler and used a pedal commander which gave me about 16 to 17 miles per gallon.

I measured out the area under my car and then found the biggest muffler magnaflow made that i could fit. My cammed ls3 is super quiet.

the TCR muffler was the perfect level of volume IMO. You could hear it under heavy throttle but otherwise very sedate for day to day driving.

take the car to the muffler shop ..ask them to remove the muffler, resonator and straight pipe the exhaust from the catalytic back.... Thank me later... Permits that 20 valve engine to breath proper... And the 2.5L is so perfectly balanced and engineered it's still quiet... Until you hit the accelerator... Changes the entire driving experience...

Yes, plus no muffler, no fuel filters or oil filters, no emissions sensors to go bad and put their hand out for an 800 dollar repair etc...

I have a resonator delete and Magnaflow mufflers. The drone is there at highway speeds, but not intolerable IMO. The acceleration sounds great.

Only issue I ever had was on a 15 Optima, welds on the muffler broke when driving between 2 extreme temperatures and it was a cheap fix.

Got the tires installed today and what a difference some fresh rubber and suspension makes. Now onward to a less droney muffler. Magnaflow sounds great but that drone is unbearable.

almost every single weld on every Walker muffler I’ve seen look exactly like this or worse

Their welds are pure garbage.
