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 have the Kinteix racing test pipes w/ resonators and no raspiness what so ever. i havent experienced with other brands so i cant say for those but i am happy with mine. if you just get the test pipes w/o resonators you will have raspiness. i would suggest spending the extra money for the resonators!!

No filament (look Bill, spelling!) issues with my Helix test pipes. Plus it sounds like a track car when I get on it.

Unfortunately i cant get test pipes, they just started emissions up in ct, and im scheduled for a check up in like 3 months. Ill be happy with cats though.

Buff, did the cats add a louder but deeper tone?

yeah that would prolly be a good route to go, but its a little pricey 1650 all together. I have a freaken nismo body kit to suit up in a month so i need a 1000 or so for the fit and paint. Ill probably stalk the forums looking for used crawford or kinetix lol

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:

Random Tech makes some nice pieces....I had one in my old car. Worked great. Free'd up some nice mid range & top end. Still remained emissions legal.....

The same place I was checkin out the mean exhaust.....had the RT cats at a real good price. Best I've seen on the web.............

It would be a very good idea to stay away from the R/T's. There have been numerous members on the boards who have had them fail on them. The honeycomb material inside the cat crumbles and can seriously block your exhaust. Just stay away from these at all costs. Well more than 15-20 members have had it happen just from what I have seen. I had them on mine and got rid of them fast because of this. All of this and they are still $80 more than the crawfords.

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:
