Headers Are In!!!
Well everybody I have finally got my Pacesetter LT's and ORY installed and it was quite the journey.
The hardest part was probably getting the Y pipe to fit in there, this required removing the rear exhaust hanger to move the intermediate pipe and the muffler back so that i could slip the Y pipe over the Driver's side header, the passenger's side header went a bit easier
As of now i just have the Y pipe clamped with the shitty U bolt clamps, i hope to get some band clamps in the near future, i didnt tighten down the U bolt clamps too tight cuz i didnt want to bend the pipes, so i have some exhaust leaks.
Over all the install went alright considering i was using jackstands and ramps, a few things that gave me trouble; removing the starter, getting the y pipe all set, getting the passenger header in ( i needed to jack the car up another half a foot), and fumbling around with the various hard to get to nuts and bolts
As for the gains, deffiently more HP in the Higher RPM's, i havent beat on it too much yet because i gotta get back in there and make sure things arent loose.
The sound it greatly increased, sounds like an old school muscle car, the ORY deffiently has a huge role in that, as well as my 40 series flowmaster muffler.
pssh.. what a long past 3 days
probably took me 10-15 hrs total to complete this job.
please post any questions at all.

I Have Flowmasters Right Now And Want To Do The Same Set Up. But I Have Been Told Over And Over That If I Do The Headers That I Should Switch To A "higher Flowing Muffler" Like Borla Or Magnaflow In Order To Make Any Gains.....thoughts?1998 Trans Am Vert, M6, Soon to be full of goodies......

Congrats on finishing the install. Definately takes some work, but well worth it. And you get a sense of accomplishment when all is said and done. Did you run it with just the headers before putting on the ORY?

I feel ur pain. I had to cut my friends off to put the new headers in. But im not complaining. It was fun, and plus his dad owns a shop, so we had access to a lift,tools,power tools etc... How do u like them as far as power? I can tell u that once we fired it up and opened the Q-tec's it was LOOOUUD

yea i'd leave the Flowmaster in there, well that is if its a 40 series, i love the sound it has, very deep rumble whereas a borla / magnaflow, would give u a different sound.
the Y pipe is giving me trouble being such a tight fit, but i'll work it out
i got a huge sense of accomplishment when i turned the key and it fired right up.
i'm loving it, cant wait untill i get the Y pipe all sealed up.

Flowmaster gets is reputation for sound not performance! With LTH's, you are getting a big enough gain that the 80 Series will not cause a big power loss! Tested and Proven! The 40 Series I have not heard yet on a Single in/out
05-12-2007, 01:41 PM #10
the 40 series i have is a single in and dual out, and sounds MEAN
05-12-2007, 02:06 PM #11
I didn't think they made 40 series with dual out.

Should have started it before the y pipe install if you want to hear mean! I installed mine last week. And since I have TD's I hve to get them rerun on the pass side to fit so I'm running open headers until probably friday when I get a chance. Loud does not begin to describe it. Awsome. Wish I had the cam installed already before the exhaust but won't have the time vacation is already over

damn, i thought maybe the pictures were in this thread. Guess not. I see digital cameras on sale all the time. Want me to forward a link to you when I see the next one?
I have getting my Y-pipe and stuff back on without banging down to a science. It's all in the angle your I-pipe meets the over the axle pipe. Then wedge some blocks of wood in the tight spots to hold it in place while you tighten everything down and then knock the blocks out. You pull your exhaust 5 or 6 times and you'll get the hang of it.
