Whats the difference between a cheaper exhaust such as Tsudo vs a higher quality brand of exhaust such as HKS or tanabe..? if the pipes are angled/shaped about the same, what really makes a difference in the sound? :eyebrow:

fitment, sound ( crap vs. something that sounds like people have done the right r&d on ).

"you get what you pay for"

materials used.
quality of construction.
sound.

welding, angles, sound, performance

^ (minus performance)

Minimal whp gains if any from an exhaust as with most bolt-ons.

simply its the quality

I dont think hes asking what is the difference, but what makes the difference in sound if all the pipes and whatnot are the same. Quality whatever, its an exhaust that doesnt do anything for our cars that make sound, unless you are going to go boost then get a cheap (atleast brand name though) exhaust. No need to get the PTuning exhaust thats expensive unless you absolutely want it or are gonna go boost eventually.

flow is important for turbo applications
