I have a 380 whp fp green with turbo back exhaust, exhaust mani 02 etc cams etc. BUT my wife is now pregnant....

I have a fujitsubo exhaust and its pretty quiet, but its still too loud to carry an infant. If I put the stock cat in, im sure it'll be more quiet, but say if I put the entire stock exhaust, how much hp do you guys think I will lose.

Could I upgrade to a fp red or black and make up that lost hp with the stock exhaust?

Whats the most I could get on stock exhaust?

Thanks in advance.

This is a similar thread that you could relate to. Some good opinions there... Read it!

I'm pretty sure you'll lose like +30 whp with the stock exhaust.

Why don't you try a HFC first? The Fujitsubo isn't that much less restrictive than stock. FWIW, I've carted around two infants in a car significantly louder and stiffer than the Evo. They never really cared. Kids are much more durable than their parents.

Have someone - either a local muffler shop or someone like DB - fab up a second muffler that will fit where your TP is now. This will not hurt performance and will still quiet things down a bit. Check with DB's brother; he did have a very quiet EVO with two mufflers, and may still.

More than true, I'd cruise it, the deep huummmmmm while cruising home might put the little tyke fast asleep. Bonus!

Congrats, by the way.

+1. I carried my nephew when he was little in my MR2 turbo track car a few times. It was fully gutted , no cats,2502 lbs with coilovers. He loved it actually. One time I had to have my sister drive it for me across town, ~10 miles, she said she it gave her a headache for the rest of the day and said something to the effect about feeling her internal organs jumping around..lol

i have a stock exhaust and the power dropoff was substantial. go with a quieter exhaust such as the greddy evo2 exhaust and a HFC and you should be good to go.

If you do decide to go more restrictive just keep in mind you may have to get retuned!
