REVIEW: Stillen true Dual and Crawfordz Cats
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. Don

The sound is really nice. I am impressed by the sound. It VERY slighly amplified the sound of the Stillen cat back. Trust me, it's a NICE sound. You will like it very much.
I believe that there is a sound clip in the Intake and Exhaust section, under the title Stillen And Crawford.

I would have to say so. Nice and deep, more like a V8, IMO. The exhaust isn't louder, just a bit more throaty....

I also had a bad experience with Stillen's service but that's another thread all together.
I'm glad you admit that your butt dyno didn't feel those 5 extra horsepower claimed. I hate when people claim they felt their car pull harder when they put their K&N filter in or put on an exhaust. 5hp on a 230hp car is like going from 55mph to 56mph and saying "I felt that!".
