Resonated Test Pipes vs HFC’s in the long run

ClemsonVQdude · 02-12-2018, 11:45 AM

Whats up guys? One more question, Got a catback system ordered and on the way. I know the differences of power and sound and all of that between TP’s and HFC’s, thats not what i’m asking. I’m leaning towards some resonated test pipes. I’ve used Berk HFCs on my previous car but only had them on there for about 8 months before I sold the car to get a Z. My question is, what is better in the long run? I’m planning on having this Z for years and years to come and trying to figure out which option is better for both the health of the car and the possibility of something happening to the pipes.
I know that HFCs have a possibility of damage to the inner core of the pipe ultimately resulting in having to put the stock cats back on or get new ones.
Do test pipes have any negative effects on the car in the long run?
Like I said I’m wanting to keep this Z and the set up on it for a very long time so wanting something for both performance and sound but at the same time keep my car healthy and avoid problems in the long run.

Catalytic Converters have one purpose, reduce emissions. So not having them, bad for the environment but they can't fail or clog even if there is only a small chance that would happen over the life of the car. I doubt any quality HFC would have problems either.

In the long run you are better off getting resonated test pipes instead of test pipes with high flow catalytic converters because eventually sometime your high flow catalytic converters will indeed fail or get clogged up over time and need to be replaced. Do you have emissions testing where you are at would be the question? High flow Catalytic converters are only there to pass emissions testing. I wish I had just purchased resonated test pipes in the first place.

Nope no emissions tests in South Carolina. Thanks for the info.
