the only purpose the cat serves is for emissions. In terms of performance it is just another restriction.

I love my TOG's. I little on the loud side but that may have to do with having no CAT.
I can imagine. I have my togs with a 2.5 inch carsound cat and it is loud as hell. My friends always know when I'm coming.

It's a game of give and take. I gain HP, i gotta give up a lil torque.

About how much performance should I expect to see when I put headers onto my current set up which is a naich cai and slp exhaust.

Both Alerosince 99 and crazy have TOG's right.

It would seem our cars would be very similiar alerosince99 if I get my headers. Roughly what are you runninng hp wise.

I'd say around a 20hp gain at the wheels with those mods. Springs dyno'd his car after he installed the TOG's and showed a 19hp gain at the wheels. I do not recall if he had a custom exhaust or intake. I'm thinking he did though.

Also is there a big difference between nickel coated and silver ceramic for the extra 200?

So your saying that just adding the headers gave him close to 20 at the wheels. This doesnt include the 4-5 should expect from adding the CAI and slp exhaust does it.

When I originally dynoed I hit right around 160. I did have a rather large exhaust leak at the time and they did the pull in I believe second gear. Third is one to one but it kept droping out. (poopy dyno operator) and they didnt have fans running in the front to create air.

I would guess with the exhaust leak fixed that Im about 165-170. I would love to dyno it again but that aint happening till the next round is completed.

yeah it was a dynojet.

Its all good as long as you stay with the same type so you can compare your past results.

Mustang dyno will typically read less and some will say it is more accurate.

Damn 167 with just intake an exhaust is pretty impressive. You must have a little bit of a factory freak. Heh or else I have a factory anitfreak! I may have to do one more dyno before the next round of mods. I dont think my base should be that far off unless something was majorily wrong.

Wish I would of had time to do a quarter this year. That makes it easier for comparisons.

Yes it is, that's what all my numbers are on.

The conversion is multiply the sureflow number by 1.1 to get your dynojet number.

152=167.2

this depends on what your looking to do with the car.
nickel is more for corrosion than anything
the ceramic is to hold in heat
the new ceramic does a killer job of that.
holding in more heat keeps exhaust gas velocity up which makes more torque
how much more? couldnt say I haven't done back to back runs with just changing between the 2 coatings.
ceramic also will not disscolor or blue like the nickel.

the runs I did with 18-19hp gains were with the nickel coated headers.

at the times of my dyno my car had CAI, tb, and exhaust before the header dyno for the base run
just headers were added between the 2 dynos

so, would you say it'd be safe to just go w/ the nickel coated and save yourself the $200?

Did you have to run an o2 simulator since you don't have a cat?

Of course. If you don't, you will throw a code.
