More 5th Gen mods on the way
Like an addict looking for a fix, I've been busy over the holiday weekend. Comparing prices, looking for deals, busting chops, etc. Since I only have a handful of things to buy for the T/A before it gets shipped out in the Spring, I decided it's time to throw some more cash at my daily (well, until it goes away for hibernation).
- OBX Long Tubes 1 7/8" with catless extension pipes
- GM exhaust manifold gaskets
- Taylor Spiro 8mm plug wires
- Wire sleeves
- NGK TR5s
- Jegs stainless 2.5" band clamps
- o2 extensions
Unlike the 4th gens, these should go in relatively easy on BOTH sides. I believe they go in from the top, as well. There's actually room to work on the motor in these lol. I did the intake last winter and it wasn't terrible. Already have the dynotune lined up in a few months with the shop that is going to "correct" the Trans Am.
Shooting for 425-430rwhp with just bolt ons.
Current mod list:
- Pypes Catback (2.5" duals)
- Ported TB
- Rotofab CAI
- Shorties (stock cats)
- GPI modded intake
- 412rwhp/412rwtq @ the 2015 LTXTech Dyno Day

2009 G8 GXP M6, full exhaust, catch can, cai, stereo

Headers are in. Just need to fix a small leak at the band clamp and move some heat shield out of the way. Picked up some PowerStop Z26 ceramic pads so that'll be next along with an oil change. Dyno tune and rear tires will happen in the first week of being out of the winter slumber.
The install was a breeze. The previous owner used ARP header bolts which is nice, but they also used Mr. Gasket gaskets. Anyone who lived in the 5th gen world for ANY amount of time will say GM header gaskets or bust. The hardest part was sticking my large, man hands in between all the wires and lines on the passenger side to get a couple bolts started through the gasket. The dipstick tube was really easy to get in, too once I realized you can see everything really well under the car.
The spring bolts on the collectors were crap but they work. I heard of people overtighening them, but the trick is you don't have to overtighten - the springs provide all the tension needed for a nice, secure fit. I replaced the old factory band clamps with 2.5" Jegs stainless band clamps - and they are really nice. However, the drive side pipe didn't want to line up 100%, so I'll need to loosen up both ends and play with the geometry a bit.
The Pypes catback was made for headers. I had to take the entire catback apart, clean it up, and start putting it back on from the front to the back. I'm glad I did, because I was really able to add clearance and the tips fit SO much better in the bumper.
I wish there weren't so many connection points in the catback. 4th gens are simple with an I-pipe, over-axle bend, mufflers, and tails. 5th gens have the pipes that connect from the cats/extension pipes (off the headers) to the X pipe. Then there are two seperate pipes PER SIDE between the X pipe and the tips!
The geometry has to be just right on everything. I installed several catbacks on my 4th gen, laying on the ground with the car in the air by myself. This catback I did the same, but needed a jack to keep the X pipe up against the floor pans during the install.
I also used copper RTV at all the connections, plus my Carhartt, jeans, and hands. Hahaha. The install took longer than it had to because I was so meticulous with everything.
I love the sound and noticed a difference right away in how fast it climbs the RPMs. I don't want to beat it until it gets a tune.
Will definitely take a dyno video and post the results. I'm thinking 430rwhp conservatively on a dynojet.
