Thread: SD Headers installed and A+++++

So I did the install with not many issues at all. I made sure all pipes fit prior to install and also made sure I had everything I needed to finish the job right. I did have to lower the subfreame and I also removed the MAP sensor and bracket too. This made it so easy to slide it in. I sealed all the joints with copper RTV and I have no leaks as of yet. I started around 1:30 and finished with clean up and shutting down the garage by 9:30. I also had to extend the front O2 and hammer the hell out of the tunnel for it to clear. All in all they came out great and I am very happy with the fitment. They sound so amazing too, what a huge diffrence over the manifolds. Thanks for all the input too guys, its really helpfull to be on these many great boards and do the research first. Now time too upload my new tune and Ill be ready for NED on the 25th. Here are a few pics foir everyone.

question time.... why in the hell do you still have your engine cover and why did you have to lower the subframe? : \

you can get them from napa for $13.

Stainless too.

Wow looks great how is the performance with them on now?

Thanks for all the compliments, I personally like the look with the engine cover on, the subframe was easy to lower in the back, took 5 seconds to do with air gun and I lowered it just enough to sneeek the rear header by. The clamps are from NAPA, my buddy got them too me for 9 each. I do not have a cat in there and have no plans of installing one either. The gains were noticable for sure, I also noticed a huge diffrence in the response and also how much faster it revs out. I couldnt be happier with them. Sounds so much better too. It actually reduced the exhaust drone I had quite a bit.

Or if you have a tailpipe test then get a magnaflow 99009HM cat.

You can pass with that cat and no EGR in ontario.

Mass. has some of the stricest emmissions test in the country actually. But I used to runa wholesale autoparts store in the area and know all the shops and have pull at everyone of them. Plus with the HPtuners software I will remove all codes from the system so they never even scan. Problem solved.

If they dont do a tailpipe test then your emissions standards are laughable.

Hey nice pictures and you have given me the confidence to buy s.d. headers and install them by myself, but i have heard there are 2 different types to buy, one fitting better. How would i tell the difference? Also, what looks to be the difference between the once that cost like $205 and the other ones costing around $185? I typed in gtp headers and they showed up. Thanks.
