This is a GN1Performance "3 INCH Pitbull Muffler" for a 1986 or 1987 Buick Grand National, T Type, Turbo T, or GNX 3.8 liter turbo V6. This muffler is constructed out of 304 stainless steel with 3" inlet and 3" outlet, with a high polished finish for that mirror look. These mufflers look and sound awesome! They do not have the "drone" sound but have a good all around sound.
*only one muffler is included per order if 2 are desired, change the quantity in the check out to 2.
