top speed header

[Suntzu]

Can anyone who gets one of these Top Speed units next ( make sure you dont get the OBX one its difference and crap) measure the diameter of the final single pipe. The one that goes into the cat. I want to check it against stock. I think its 2 inch.

Yeah I aked the seller prior to bidding to ensure its the topspeed.

Let me know if anyone is interested in Topspeed. I have the guys email and he said he can do a bit of a discount. He has marked the price up since i purchased.

ask him if he can get 5zigen race headers.

^ Cool let me know when you guys are getting your flex pipes!

Would i be correct to be going for the 2" x 6" double braided?

Im in Sydney so considering getting it done by Westside mufflers since they have good rep.

I'm in Sydney too, so that would be good....

is the sound that you are mentioning a "hissing" sound?

if so it's from the flexpipe, dcsports headers got that hissing as well.

that the sound it looks like.
i saw it was somewhere leaking, but my friend checked, everywhere is fine.
so, it is normal then.
but i still dont understand why top speed header is smaller than stock header?
but it is lighter than stock header for sure.

how big for the stock one?
from what i see, the top speed looks smaller than stock.
but the way, is there any good cheap catback to use?

keep the stock exhaust as its good unless you just want them for looks. What i mean by looks is if you want cannons.

so, u mean i keep the stock catback? does the catback increase power?
i have the same idea as well. cuz catback cost me too much to spend.
i just decide get injen intake and header.
but the "hissing" looks so strange. i think i need time to used to it.
should i change to other header if i have chance?

Just change the flex pipe.i think you can get a double layer one.

The increase power from cat back is minimal. The catback on the stock CL9 is optimal. Change your cat, that will give u some more gains. Go either magnaflow or rt cat
To get rid of the hissing, change the flex pipe. It doesnt cost that much. Im waiting for my topspeed header to arrive as well. Im just gonna change the flex pipe straight away to avoid any complications or issues with hissing.
Swap the flex pipe to a 2" x 6" double braided flex pipe as mentioned by Tony.
Im not sure where to source it from. Tried ebay but not much success. Anyone know?
