Well guys,

I installed the Crawfordz cats on my 04' 6MT this Saturday and would like to make a few comments....

First, I am not totally in love with the ghetto exhaust clamp "brace" technigue employed by Crawfordz to reinstall the exhaust brace. It consists of an exhaust clamp with a piece of metal that kind of elongates the brace so it can be reinstalled. The exhaust had about as much movement WITHOUT the brace as it did with it on.....what's it even there for?

Second, I think Crawfordz needs to include NUTS with it's new BOLTS that they send ya. I have an aftermarket exhaust (Stillen) and i know the stock stuff was all studs, but the Stillen isn't. Thank God that I was at the Infiniti shop that my brother works at, and he had enough nuts to install these cats.

Third, the thing smoked after the cats warmed up. That's totally normal, I know. And it smelled, I probably got cancer from the noxious fumes, but oh well.

Fourth, and don't get me wrong, but I took the car on a 70 mile "break in" drive, I was pleased with the sound. I don't "think" the exhaust got any louder, but there is definately more "drone". Not the "bad drone" but"drone". I am used to this having modified a few Mustangs in the past with similar exhaust mods, so it's not really that big of a deal. It seems to really resonate about 4000 during spirited driving.

Fifth, my butt-o-meter isn't fine tuned to feel 5rwhp, so I really didn't feel any gains per se with the mod. Maybe the ECU is "learning still", and maybe I got gains, but just can't feel them? Who knows.

The bottom line is that I am not really impressed. Sad but true.

Have to save for a tune, and maybe the numbers will wake the car up? Who knows. I am just not feeling it right now.

no problems with 1 and 2 with my HFCs

3 scared the shiets outta me

andrews fast intention high flow cats actually reduced the drone that he had with his injen exhaust

sorry that youre not as happy with them as you may have thought you wouldve been. definitely save up for a tune...but wait to do that after youre done modding, imo.

 

I had Kinetix HF cats on my borla and it added a ton of drone.

 

That sucks that youre not happy with it Diamond. Hopefully that tune or your computer will eventually improve everything. I still haven't had my stillen and crawford cats installed...Thurs is the day...hopefully.

 

yeah, gotta get it tuned to know the difference. I have a similar setup and the Unichip made a very noticeable difference in the mid range.

 

Yea,

But ya know what? My HFC's don't have that annoying *** rattle that seem to be prevalent on some "other" types of HFC's.....so if there is a silver lining to this cloud....that's what it is.

 

And the bottom line is that these cars are not mod friendly.
