header with catless DP...then you'll hate it...lmao

 

i got the gmpp cat-back but it was to quiet...i took of the resinator and cat and ran strate pipe and it sounds good....loud and clean

 

yah well if you want to get a better idea, have your car door open and lean as far out as you can while still reaching the gas pedal and then rev it..(and of course this is in neutral lol). anyways i bet it's louder than you think..

 

cut out the resonator and cat..sounds loud n good and u get better air flow...i ran strate pipe through....works great

 

Ive got the megan on my car and friend has the Sport on his and I cannot stand driving his car because of it being so much quieter than mine. Definitely a difference, ide go with the trade man!
