Got my new exhaust setup today, and I love it. It's really nice and deep, loud, but deep. I can also notice that it pulls a bit harder.

The setup is:

2.5" Downpipe
3" Flex Pipe
3" Carsound Cat
3" Mandral Bent Catback Exhaust
Magnaflow Muffler

BTW, it's on a 99 Prelude.

One question: It lets out a bit of black smoke when I really get on the throttle, is this normal for new exhaust?

Anyway, here are the pics:













So to Maganaflow!

Comments?

Looks nice. Hows it register on the butt dyno and how does it sound?

Yea that's what I'm afraid of. Any other ideas?

 

Nice Setup!!

Too rich isn't necessarily a bad thing.

better rich than lean.

if you were too rich you could wash down the cyl walls, but it would be very noticeable... strong smell of fuel, lots of black smoke, rough idle, etc.

 

With more flow the car will run richer. Like when you remove the exhaust it gets richer and when you restrict the exhaust it leans out a bit. Since you may have more flow with this exhaust the car might run a bit richer, that would be the cause of the black smoke.

Any other comments or compliments?

Wrong, exact opposite, with more AIR it runs lean. your getting more CFM's of airflow at the same map values, sense your ecu still sees the same map pressure values at a given RPM it gives the same amount of fuel, which causes a lean(er) condition, this is why MAF's are better than MAP's.

 

Which shop did you get this done at in the Seattle area? Will you do a breakdown of the prices for each part (piping, cat, welding etc)?

IMed

 

isn't it sposed to go over the rear LCA? not under

and id say a little extra smog out the back is normal bc of the hiflo cat...

 

I'm going to try and get a video up today after work.

 

the muffler tip looks really shiny (polished) compared to the muffler itself. did you weld a diffrent tip on the muffler?

Yea there was a stainless steel tip welded to the muffler.

 

until you get a vacuum leak and run lean.

 

have u retuned with the new exhuast?

did u retune the car after u got the new exhuast cuz you might be running lean or rich with the extra flow

 

for using a cat.

It looks good. Damned good.

IMO, lose the Magnaflow and get a Flowmaster. Sounds ricey as it is.
