Default Crawford or Helix Hi-flow Cats?

Im kind of leaning toward the crawford cats. I did some reading about them having clearance proplems? Has anyone that has the Crawford cats, have any clearance proplems? if so how did you resolve them? Im looking at ordering them sometime this next week.

Thanks for any info

No clearance problems here. They fit and finish were excellent. A quality product from a quality outfit.

Lou I as YOU know recently got my Invidia true dual and will be adding the Crawfords. How much louder did it get and was a increase in power felt. My other concern is if it gets raspy.....Chime in

Can't answer the question, I had the Crawfords before I got the G200. Sorry. But, I can tell you, It is not Raspy in any way shape or form. It's quiet at Idle, but bellows at high RPM, sounds very exotic. Also, there is no annoying drone in the car when on the Freeway with the Crawfords and the Invidia.

this is helping me out. The way Lowrider is discribing is that its not raspy but has a exotic sound, witch i like. Hope it has the same sound with a nismo.
