It was a busy weekend, Saturday I moved my amp to the little pocket in the trunkon the left. That was a bitch, I had to make special brackets so it didnt just lay in there. Today my dad and I put the exhaust and Cat in. Those bolts connecting the cat to the downpipe sucked large testies but over all it took us about 3 hours to do it all. I drove it around a lil bit and it sounds real nice and there is a noticable power gain. Oh yea and after I drove it for the first time, the stainless steel turned gold, I looks pretty sweet.

The Cat

 

Nice amp install.

 

I just need to get a Chip and DV and I'm set for now.

 

looks nice chip will be great

 

I just went out driving again and there's a great difference from stock. Where dose most of the power gain come from, the cat or the exhaust?

 

And what should I do with my stock exhaust and Cat, sell it, keep it?

 

The answer is.............both.

You probably gained about 7-10hp for each mod.

So, 1 small mod + 1 small mod = 1 big mod!

The increased flow spins the turbo faster, so more power.

 

Who's HFC did you install?

 

When installing the exhaust, did you need to weld anything? I just got mine in yesterday (Borla, catback), but I am still waiting on my HFC to get made and be shipped.
