Ok replacing the whole exhaust system in a week or two, all im missin is the cats,
Has anyone heard numbers on Ultimate Racing cats? I heard they are good, i emailed the company and this is what they said
"Unfortunately, we never dyno'd our high-flow cats alone. It's rare we dyno exhaust products as exhaust systems are generally horsepower unleashers and not makers. They generally unleash power that is already on tap at the motor. The power they make heavily depends on the amount of modification. For what it's worth, we've sold many high-flow cats to the Z population and have always had positive feedback"

so im looking for best bang for buck, no raspiness, and lookin for a deep tone
heres the list
UR= 495
Crawford 5-10hp $550
Kinitex, eh 4-10hp $385 are there any problems with these
RT, heard too many bad things

I dont know, its hard to dish out $500 without numbers

ps. i am putting on injen ses straight, top speed headers, JWt intake and motordyne spacer

I've got Crawfords and have had no problems with them.

UR - has had some issues witth the filliment breakiing down on some folks.
Kinetex has had some of the same issues in the past, but may have fixed their problem.

it's tough for me to tell. I replaced my entire exhaust all at once.
I would recomend stepping up to the Crawford Headers though - well worth the $'s.
That's not only my opinion, but the same from everyone that I've talked to that's got them.

I've only ever seen used Crawford Headers once. The guy that had them was turning his car in & was returning it to stock. I think he got 800-900 out of them used.

I know that it's steep, but Headers are definately one thing that you don't want to install more than once. It took me & Peptidbond more than 16 hours to install them in my garage on jack-stands. (Both times we did it) I'ld hold off until you can afford to get them. Just my $.02 :shiftdrive:

Peptidbond & I have the same set-up except for the cats. I have Crawford's & he has the Kinetix. I can't tell a difference between them when we're out & running around.

IF you're seroius about going Turbo (I'm assuming twins) then save your $'s!
Go to the FI forum & read Going Deep's write up about how to do Turbo's right the 1st time. You may as well start now & that way you'll have everything that you need when you are actually ready to do the install. (instead of waiting on parts & such to show up)

Now if you're going to go with a single Turbo unit - then the Crawford Headers are a possibility according to Peter from APS. I'm almost positive that they will work with the Turbonetics Single as well.

Just some things to think about :thumbsup:
