Pontiac G8 2008-2010 - G8 ARH header system sound clip added!!!

So i bought a stryker blue G8 about 2 months ago, the car is faster than i thought it would be! Only problem is it is just so damn quiet, no V8 rumble at all. So i ordered a set of 1 7/8 headers with high flow cats and X pipe. Needless to say i cant wait for them to get here!! They should ship the middle to the end of the week. i ordered them last week so i was kinda surprised it takes so long but quality takes time. Any tips on installing them?

Im of the same opinion of you, way to fn quiet. I will be doing the same soon.

lol yea, when mine is running you cant even hear it

Look out for the dipstick, and be sure to mark your steering shaft if you unbolt it.

are you talking about where the two peices connect? if so then im assuming that it only goes together one way?

Some people just mangle it trying to get it out. Its in there pretty tight lol

hmm.. does it have to come out? is it hard to put it back on once you take it off?

Ive read horror stories on the G8 forums about the dipstick. I will document my install just incase I figure and trick out and/or for reference for myself and others.

My advice. First figure out the most logical way to maneuver it out. Two, firm grip, ill say it again, firm grip and PULL! Dont twist it and bend it all up! I believe the bolt that holds it to the block is a 14 or 15mm

i cant wait to dig in....it seems some have probs and some dont lol. ill have a friend helping me and we are both mechanically inclined and use to working on cars so it shouldnt be to bad!

When in doubt, beat the mother fucker out ;)

Only trouble I had was with the tube. I had it back in but it wasn't the same lol. Livernois installed a new one for me when they did my cam n stuff. It will still be shockingly quiet with stock GT mufflers. I suggest getting some GXP mufflers to make it perfect :)

First time i had no problem with the dipstick tube, but second time it took me 15 minutes. I was pissed and I'm not sure why it took so long. Before removing it, find where it is located.

I will see what it sounds like first, hopefully its just right

the headers should be here tomorrow but i cant install them till sat or sun. i guess i will have a baseline for the car bone stock before mods anyway!

It's not just the dipstick location / relocation... disconnect your negative battery terminal as well, otherwise you may find yourself spot welding the dipstick to the starter motor. Ask me how I know :D

headers and x pipe are in! pretty straight forward install, the dipstick was a pita but other tan that it was cake! i wish i could report some 1/4 mile times but they closed the track due to it being to windy :(. i wish we would have called first since it was an hour and a half away but you live and you learn. Car is still very quiet but sounds way way better and even thou its not tuned yet its def faster. the arh system is top notch, fit and finish are superb!!!

installing GXP axle backs today! i am surprised at how quiet the car is with the headers. hopefully it wont be to loud but we will see!!!

You'll love it with the GXP axlebacks! It's got a little more at idle but can still be suttle. Wide open will sound great also! I remember being shocked at the lack of sound when I fired the car up after the header and x pipe install with the GT axlebacks.

those were my thoughts exactly...shockingly quiet. the gxp's sound great just as you described a little rumble and nice wot sound:drive:

sound clip..........!

Ok ill make one. Not sure how to post it thou

My car sounds good and has 2.5" X pipe then 2.5" dynomax bullets then 2.5" tubing to the sock tips i had widened to a 2.5" inlet. sound is soon to change though :)

i have a video but i cant post it. it keeps telling me a security token is missing?

I am interested in how your car sounds..I am looking to add arh 1 7/8 headers and catless X th my gxp.

Since ARH Is around the corner from us, I can vouch for the fact that the fitment and sound on anything They make is killer.

I agree mike as I already have a set of their headers and catless y on my z/28.. Just curious to see if it will sound similar to my brothers vette, who is running arh, catted x and stock z06 titanium axle back on his 03 z06.

I will get that video up so you can hear it fatmat

I'd go with ARH as well! Top quality and fitment. Got a great deal at Juiced Motorsports. Pretty sure they are a sponser here.

^^^yea i bought them from you lol

I was also surprised at how quiet mine was with the headers and stock mufflers. My Solo Performance exhaust is a bit loud for my taste though. Anyone have part numbers for the GXP mufflers?

ok here we go!! let me know what you think
