humm, if you are concerned with rasp. a custom y-pipe isnt much and you can have them weld in 14-18" resonators

 

mcduck-as I said.. many people were not honest with me when I asked about the helix TP... Briguymax was the only honest one out of like 10 people I asked....

Zivman-thanks for those pics...those look very nice!

Everyone else- THANK YOU for being honest!! I would have been pissed if I spent $500 on crawfords and got rasp..(even tho only some get it) the risk isn't worth it to me...

 

i am thinking of going back to my stock cats as well....the helix test pipes just don't sound good.....

 

I've had Crawfords Cats for about 6 months and no rasp until a couple days ago when it started to have a really loud raspy noise. I'm not sure if one of the cats are busted but im gonna get it checked out tomorrow.

 

i have crawford cats, fuji y pipe and fuji ti catback and i have no rasp what so ever. at first, i just ran the cats for a while and i was very happy with their quality, fitment, customer service...and NO RASP at all period end of story. you will not be dissappointed with the crawford cats thats for sure.

i would definately not go with test pipes or rt cats

 

My Kinetix cats had 0 rasp when I had my stock exhaust. Once I put on my HKS exhaust and let it break in, I noticed there is some rasp with the throttle wide open between 3000-4500 rpms. Before and after that it is fine, and if the throttle is less than 100% its fine also.

 

There's always the option of keeping the test pipes and slapping on a Turbonetics single turbo kit. You won't get any rasp and you'll be flying in the 1/4 mile.
