You'll need a bolt splitter to separate the catback bolts. Even on a creampuff like mine, after over a decade of Seattle weather they get rusty and had to be split.

03 gts tib
Starting a project on a tib I just acquired with 111k miles.
Stuff already done:
New battery
New timing belt
New rad
New water pump
Etc new cooling system
[email protected] air filter ( in box have bad exp with CAI and short ram in past)
Future stuff I already bought pending install:
Ebay headers
Ebay catback ( basically borla replicas)
Future plans:
Chase206 ECU reflash
Upper and lower IM aftermarket
Weight reduction (not taking the spare or jack out just general weight reduction not one of THOSE guys)
Pearl body paint (exterior is very best up luckily no dents just rust and wear and tear)
Elantra rotors for weight reduction
Lightweight rims
Will post pictures of the poor girl after work she has no make up right now but will be great soon
I always was a fan of how tibs looked on nfsug2 I always chose it as my car.
I know "gts" tibs don't exist that's just what I will dub her

Welp did 3 Dyno runs with perf expert one was 144 whp 146 whp and 147 whp so this one was about in the middle though it was the last run of the three.
So a gain of a couple hp from a good filter and heat wrap seems legit.

He probably did only the lower because the upper is gard to port even though it mainly only needs porting on the last 90 degrees the rest of the upper manifold is already huge and to port that you have to cut the manifold open and weld it back. Also of you do port just port to the diameter of the factory gasket and make sure your porting evenly.

Like rushking19 says, the upper is more difficult to port properly. You get the most gains out of the upper by modifying the 90 degree turn just before it enters the lower intake manifold so cutting one open isn't required. I roughly covered my port job on both upper and lower intakes on the following blog posts. Note that I used flap wheels which take a lot more time to complete. But it's harder to screw up with flap wheels because they take out less material. It is recommended to port the upper to the OEM gasket size, then port the lower to just above the gasket size to ensure you have no turbulence in the transition between the two manifolds.

I ported the upper and lower IMs to 49 and slapped them in. Btw what "stage" is 49mm ?
![Hood Automotive tire Motor vehicle Automotive lighting Automotive exterior]()
As chase said no way its 49mm there's not enough metal and even then there's not enough head port to support that 42mm is like the biggest I'd go thsts where the very opening of my fastco Motorsports lower intake manifold is ported to 42mm and that alone supported 265whp naturally aspirated on their cars. So 49 wouldn't even work at all.
