These are the torque specs from the service manual.

Bolts/nuts on the header to the block - 33 ft-lb

Bracket bolts - 17 ft-lb

Sprung bolts to Cat - 16 ft-lb

 

Hey sweet, now I can torque them down when I check them this weekend!

Thanks Ldweng!!!

 

your write-up was helpful although i think you got a lil mixed up on the order of procedures i.e.
3. Still from the bottom loosen the bracket connecting to the header using a 12mm. Loosen at the header as well as the bolt connected to the transmission.
4. With 12 mm remove the bolts with springs connecting the downpipe and the header. I had a air rachet which is soo handy

should be 4 and then 3. maybe im just mechanically retarded, but loosening the bracket first caused me to bend one of the spring cat screws . there was nothing to support my muffler while i was trying to break the nuts loose finally re-attached the support and had no more problems. no big deal like i said im a lil mechanically retarded and i am sure others are out there!

Did you paint your exhaust? It looks black in the video.

 

If I remember correctly I think he did, along with SciroccoTDI and myself. There's a couple threads on it if you're really interested.

 

If and when I do get an exhaust, I plan on going the route of the flat black... I saw the post on the Megan double tip exhaust painted flat black. I like that look a lot. All stealth and 'murdered out.'

 

with the headers how much did your car improved... because i just ordered my new megan headers the other day and cant wait to get it...

 

hey zangoose!!! cant wait to hear the exhaust with the headers man...you planning on running a test pipe?

 

yes i did paint the muffler and about two inches of the twin pipes looks really good .i finally added the mid pipe so i am cat back now with the header. i will make a new video the old video i didnt really get on it so it sounds really mellow, which in fact it is but you dont really hear the true sound untill you get around 3000-4000 rpm! look for it today! by the way i cannot take credit for the painted muffler got the idea from someone on this forum ..great idea though, especially on a white fit!

 

im thinking about dude but not to sure yet... but i'll def. will get it when time is right... right now im making plans to race against my friend Spec V... thats his car by the way YouTube - Spec-v with a greddy Evo2 Exhaust Soundclip

 

noticed a significant difference with just the header and intake. but when i added the full cat back it really gave it a nice boost around 3000 rpms!
