Hi.
I am looking for a pair of high flow cats for my SC G35.
I am leaning toward Random Tech or Kinetix.
I have also heard Berk is good too.
Which one would give more gain?
There are also Apexi, SARD and HKS too but they cost $1300+ which are way over my budget.
Any other recommandation?
Thanks

Well some HFCs have brackets and some don't.
But even with brackets some HFCs still crack.
So I want to get more info on them.

 

I've had my Berk Metallics for almost 4000 miles. No problems here.

i didn't install them yet but i did a very long search b4 i buy them ,and the best customer service

 

How does Crawford compare to Berk? I've heard Crawfords sound better, but it seems like Berk is the favorite around the forum. I'm interesting in buying some HFCs also, and I'm looking for one that will change the sound of my exhaust the least.

 

that's a lot of miles

 

alot of info here....i started this one awhile ago.

I have had both. IMHO, Crawfords have better sound, but Berks have better fit and finish. Crawfords are DEFINITELY the one which will change the sound of your exhaust the least.

Thanks, I'll probably go with crawford unless sometime within now and when I order them I find out they will definitely cause CEL issues. But for the time being I want to enjoy the sweet sweet sound of my new exhaust without HFCs or TPs

Edit: I just read basically that entire thread posted up above. Lot's of great feedback for the Berks, including and before and after video of Berks on a stock exhaust to give a feel for how they will change the sound. I'm back to square one, this will be a tough decision. Maybe I'll wait for some good vendor deals.

 

Here's the big thing for me. If you EVER have an issue with your Berks, they will back their product 100% and make sure you're happy with your purchase.

 

Just get Berk and stop thinking about it. It's a good product.

 

Fast Intentions. Nothing beats the quality.

+1. Right on the money.

 

ive seen berk test pipes crack, berk hfc's even with the built in foulers throw cel. take it for what its worth.

 

Seems like every one leans toward Berks...
How's Random Tech?

 

Doh! I'm going to edit my post and cry now.

 

Who has thrown a CEL with Berk HFC's when they had the o2 sensor in the no-fouler bung? I've never thrown a cel.
