crappy sounds a good possibility, but doesn't the majority of our back pressure come from the downpipe and cat?

 

if you think about it it will help a little just a little but not neglegeble do to how the set up of the fwd setup is two in to one into one or two exaughst. if it were rear wheel drive it would feel a little drifferent because there is more room for actual room for two banks of pipes

 

crappy sound is a for sure thing lol and if you're doing 4" straight pipe in the interest of performance you would have probably already done a downpipe and if you were doing 4" straight pipe it would probably be the 3" downpipe which would just be the worst investment in the world because the car would be as fast as my bicycle in lower rpms lol
