Thorley Header Project Update
I'm sore and my hands have a few scrapes. You would have to be a magician to do it in 4hrs, but it is doable for a normal person. Maybe if the old exhaust was already off you could put them on in 4. It's like 1hr putsing with the air intake, spark plug wires, strut bar, rear coils and valve cover, old downpipe, crossover etc. The front mani is pretty easy except the bolt by the coolant temp sensor. The rear is a fun time.

I got mine installed last night, my buddy slapped them on for me. Overall he said it wasnt as hard as he thought they'd be, he had maybe ~6hrs in the install, but he's no stranger to a wrench. I hope to get her tuned in the morning and have the stock exhaust mated back up (I've been running around today with open headers, lol), our goal was to slap a cut-out in place of the cat, but it was way too short. I took it to an exhaust shop today and the guy wanted 50 bucks to weld up the cutout and ~4-6 inches of pipe to mate up with the stock exhaust, so I said no thanks. I know I can get it done cheaper than that.
On a side note, do you guys think that welding a cutout directly to the y-pipe/down pipe is a bad idea??? I know it will be fairly low, but I dont see it scraping on a non-lowered gxp.
Also, I think the car is in dire need of a tune. I honestly cant feel any noticeable power increase, probably just due to the fact that running open headers is messing with my ear to butt dyno ratio, lol. Damn thing is obnoxious right now. I'll update tomorrow if my tuner can pencil me in.

50.00 bucks is a steal.. I paid 80.00! Got totally ripped off, I was pissed...
Your have no back pressure so your losing massive of low end torque.
I'm running rich as can be right now. The smell burns my eyes and pisses people off at the drive thru. Smells like an old schoolm carbed V8... Runs and goes like a bat outta hell though.

I still need to dismantle the res section from the dp. Damn spinning/rusted bolts.
I'm doing a bolt in cat/straight pipe option and I'll find out tomorrow if it wigs out with no rear o2 installed.

All I have close is an auto zone and it sucks, so my parts runs end up being 20-30 min. I'll have to cut those bolts off and get new ones, but places are closed easter I suppose. Maybe Monday after work. If I wasn't leaving at 6am I would consider driving it open.

LOL, I didnt know how else to phrase it.
I was able to get the car tuned today and now I can honestly say it feels MUCH stronger, but he didnt have time to put it on the dyno for me to back it up with any numbers
He's busy with tuning numerous customers for the kyhorsepower.com shootout, but he said he'll slap it on the rollers once that's all said and done (next weekend). I think I'm happier now that the exhaust is hooked back up, lol, open headers were just too much.

The dp to cat back gasket is special order at the two places I checked. Going to head to a few exhaust shops Monday to get it punched out or maybe they have one in stock.
It's quite a bit louder without the exhaust on... at least with the door open.

Felling excited too. Dropped my car off this morning and told my mechanic to give me a shout if you get it done today. He's a really good guy and is super honest, but said he doesn't want to rush it and he was planning on me picking it up tomorrow.
