Looks and sounds great!

Tell your passenger if they ever shoot vertical video (#3) again that they're walking home.

That does sound nice. Please remind me what custom exhaust you have. Also, now I remember that custom intake you did. Are you pleased with the performance?

Yes, I feel better response and engine breath better for higher rpm but not big changes in low rpm. More sporty engine feeling with better usable rpm range in the high side.

It's difficult for me to get a big gm engine here in my country but in the states or in Canada a better engine is more a clever solution if you want a big improvement I think.

I've ported the 6 loggers headers and I have removed the restriction in the y pipe and I have modded the upper intake manifold dawg mod and more volume for the plenum

For the exhaust is a custom with round muffler (50cm) inplace of the cat, I don't have a cat you can see the picture below.

I don't hear enough squealing tires around those round-a-bouts.

Good low tone. What brand/model did you go with for the muffler?

A Generic universal round muffler 20 inch long like borla for example inplace of the cat but see the picture, the exhaust must be customised because the stock has different pipe for the muffler and the tone is different than mine.

Other example in the states with the 2.8 v6 :

Custom, exhaust with cat 2.5 in the stares

See the comments with a sport cat and a small round muffler than mine custom muffler but the tone is very near

My fiero doesn't have cat

Nice car and one of the best sounding exhausts that I've heard. You probably picked up 10 more horsepower. I noticed very little traffic in the videos allowing for a more aggressive drive.

Zobari, did you notice a loss in torque when you removed the y-pipe restriction? I ask because one of the mods recommended to improve HP and gas mileage for Holden Jackaroos (Isuzu Trooper) on the 4x4 websites down-under is to remove the factory installed restrictor in the exhaust system where the left and right exhaust headers join. I remove the restrictions in my '97 3..2L Jackaroo and the mileage and throttle response was much better. The seat of the pants dyno, however, said that the low end torque had suffered some. According to other post on 4x4 boards this is normal. Just wondering what you experienced on your car.

Lived in Bocholt for 4 years while stationed in Belgium. Played American football for the Leuven Lions during that time as well.

BTW, car sounds good.

I don't notice any difference in the low end personally, the only change that i feel is after 3500-4000 rpm

With the Fiero gone, I'm sorry to hear that you'll apparently no longer be frequenting here. You've got some impressive fabrication skills, and I've enjoyed reading your posts. Good luck with your next project, whatever it might be!
