hey i'm a real newbie deing to get a exhaust system but never ever got any replies so .........





alright , i own Z SI and i'm trying to customize exhaust with



either HKS, or MAGflow



but before that i have questions



1 what are the difference between straight pipe , x, and y pipe

any performance ,or sound difference?



2. on mufflers place where inlet and outlets are different

for example one has center/offset , center/center, offset/offset

dual/dual , center/dual , any performance or sound difference?



3. 5inx 10in , 4inx 9in , 5inx 9in what are these number reffering to?

and any difference sound or performancewise?



4. I need translation on this haha

[3" pipe from the cats--->back to a Magnaflow muffler. I put a custom 4" tip on it because I didn't like the one that came on it.]

and this guy also said he removed y resonator , and rear silencer ( is this called rear resonator ? same thing?)

what im trying to do is get magnaflow muffler 3', put 3' straight pipe from the cat. so if i set it up like this i won't have the rear silencer right? but i will have y resonator ? am i going to the right road?



5. I'm also trying to get hi flow magniflow cat. if i install this on top of my setup(magniflow3' ,straightpipe3') what exactly am i going to hear from it

i mean what kind of sound changes can i expect from installing hi flow cat?



6.So if i do 3' magniflow mufflers + 3' straight pipe(with which ever resonator that goes in that place where pipes will be[rear reso??], delete) with high flow cat,

do you guys think i will lose my torque or power in someway?

and how loud do you think it will be rate it 0~10 thanks



7. finally last thing, if i put aftermarket freeflow resonator am i going to lose alot of sound? and do i lose power by adding reso? or removing it?



please give me ALOT of feed backs

or even share me the exhaust system you possibly own , idc if it's a plastic coke bottle stuck in your pipe ,



JUST NEED ALOT OF FEEDBACK

THANK YOU

ps: after i get a familiar with these numbers , shapes , x and y s

i will try to install it and post videos by this week

your support will be greatly appreciated



have a Great day
 
you need to consider this carefully. a friend did something similar on his 2.5 Z4 with terrible consequences. nice noise no torque over 1,000 euros spent and all to no avail.

the way in which the gas combines from each part of the front and rear cylinders is important regarding how the engine makes it torque.
