Berk HFC or Berk Test Pipes?
 

Does anyone have Berk test pipes? I find alot of info on the HFC's. can't find any vids of the test pipes either. which one would you choose. HFC or Test pipes. Let me know. thanx. -Bobby

With the gians that people are getting of the HFC, I don't see the need of test pipes unless you are racing.

i got test pipes.. because we have no emissions testing, and they were cheaper

thanx guys. ya no emissions here. lucky me.

I would consider resonated test pipes.

ssqpolo has the Berk test pipes, and he loves 'em. If you want resonated test pipes, GTM has them available.

^^yes i do. u will definitely feel a difference. makes the car sound mean as well. DannyGT did not like the rasp, so he got resonated test pipes from GTM. i got testpipes because they provide more power (slightly over HFCs), they were cheaper...and no1 else had them at the time. The rasp is not bad at all (my opinion). its only from 2500-2800 rpm under accleration. i do mostly highway driving 70-85 mph...and i cant hear any rasp/drone while driving. i think it really brings the car to life. if u wanna stay legal and have great performance...go for the HFCs. if u want a more raw sound...do test pipes. if u dont want that rasp..then go for the resonated! good luck and post some results!

We have seen some awesome gains with our HFC's. When we tested our HFC's Vs. Test pipes we found that the test pipes only produced about 2 horsepower more than the HFC's. Here is a clip of DDM's car just in case your worried about the sound or the exhaust being to raspy.

I saw that the test pipes have a mech. cel fix. Does this work? Also do you think that the cel fix in addition to some spacers or plug foulers could remedy the cel or is it inevitable? also is the smell unbearable? I had them in my vette and it was pretty bad. I plan on staying with the stock exhaust and possibly a y pipe. I am looking to do these in the near future so any help would be great! thanks in advance

Do the test pipes! Just because I am curious to see more people's impressions of them. I would have probably gone test pipes myself, but the Redline Time Attack rulebook states that I need HFCs for my class. :( The HFCs have been incredible though. And still no CEL for me with three track days, and ~4500 miles. :D

If you have no emisions testing get the Test Pipes they are cheaper and more free flowing!


DAN

so if you get test pipes, there's some sort of leakage possible?

can anyone who has a better knowlege state a few pros and cons on HFCs and TEST PIPES? MUCH APPRECIATED

leakage? I didnt say anything about leakage, and i have a knowledge of the parts just not any personal experience on this particular car.
The test pipes like stated above are more free flowing, cheaper, proably lighter (not enough to make a significant difference though) but they will not pass emissions, they are louder than HFC's, sometimes depending on your exhaust set up you will get a pretty bad drone as well as a raspier sound. There is a thread i believe test pipes vs HFC, that goes more in depth. My question was simply do they give you that bad gas smell and has anyone been able to run them without getting a CEL.

The smell comes from the fact that the exhaust gas hasnt been burnt again in the cat making it cleaner and less smelly. No leaks, just straight out the end of the muffler.
