R18 Header... Topspeed vs. Weapon-r

[sjuergens88]

I am looking into getting a header and was wondering which header would be better the weapon-r or the topspeed auto? or if there are any others on the market...

[kamil2004]

they are both crap lol from people complains , i am waiting for megan

[Zeuceone]

megans header has been running for awhile with no problems.

[koonce727]

^^^same has top speed. Ive been fine.

[mistergizmo007]

yup topspeed auto is fine been running and beatin it up for a while now....

[Johnbro]

i would prob just wait and trade your car in for an si. thats what im going to do

[Truplatano]

i thought megans was already out?

[Truplatano]

[mistergizmo007]

How's the sound for the guys that have them? Does it sound too raspy and ricey?

which one do you have?

[Truplatano]

what's the diameter for each of these, 2.25 or 2.50

[koonce727]

^^ to be fully honest i didnt measure the inlet or outlet, and im not sure what they advertise, i will say it is bigger.

Sound is great. Mine sounds amazing with my magna flow. I was shocked when i heard the sound clips of that megan, god was that clip ricey. Mine by no means i ricey or raspy. The sound of just the magna flow by itself was deapend and sound increased some but not much. I love the sound. I had my brother drive off while i stood behind, along with many drive by..etc etc. and it sounded great.
The manifold does make some noise as you can hear it "hissing" as the air rushes out. I kinda like the sound.
TSA ftw

weapon r states that there's is 2.5 which would be perfect because i wanna do a custom 2.5in piping leading to the HFP muffler..

[mistergizmo007]

hey koonce727 i get alot of back pressure do you ???? im running cat back greddy evo 2 and topspeed header and megan down pipe... even when i idle still have that lil bit back pressure and when i gun it let the gas go man it LOUD but no back fire so far just alot of pressure... I love it though.... again its been a while so far so good no cel light......

i have the weapon-r header with downpipe and the weapon-r cel eleminator. idk wat it is but when its at low rpm i just hear my exhuast going. but when i have it guning at high rpms it sounds like a whisp sound coming from the header. idk if its the header because it takes out the cat and thats how they are designed or there is a leak. does anyone have the same problem? let me know if you guys have any idea what it is!

[Truplatano]

sounds like a leak, but i of course wouldnt kno unless i was there. I don't believe there should be those type's of noise's coming from a race header, but ask weapon r they would be the best people to tell you what could be causing the problem.

[Checoman]

Any videos ??? no matter what I like the sound of my R18 all stock .. haven't heard any with headers so far .. so I'm curious

mine sounds like shit too when you hit the gas. sounds like a nasty exhaust leak. i was wondering if anyone else had this problem. now i found my answer. sounds ricey right? like ebay exhaust?
