Ok, so John and I got together tonight and made a sound clip of both of our exhausts....one after the other, just for comparisons sake.

The two exhausts are the GReddy EVO2 and the Injen. Both systems are true-dual systems. Johns' car has a Crawford plenum, mine is stock. My car has Random-tech Hi-flow cats. I'm not sure if John is running stock cats, hi-flow cats, or test pipes...I'll let him reply to this thread.....

Since you can't "see" what's going on, here's the narration of the clip:

We each did a series of REV's, one to around 3-4K, one to 5K and one to 6K rpm. I went first. Then, just for fun at the end, we both revved to around 5K at the same time.....LOUD!!!

Enjoy!!!

They both sound great guys. And yeah, I agree (even if you didn't say it here), John's is definitely louder.

I'm running test pipes, hence the reason the exhaust is amplified. I was quite suprised to hear how docile the RT cats w/ the Evo2 exhaust were. In retrospect, I suppose the obscene loudness of my exhaust should scare off any wildlife that would have otherwise jumped in my path (Mother Nature and I have been at war for a long time).

Anyways, it was nice meeting you Kelly... thanks for investing all that hard work into the audio clip.

Very Cool Guys! My boss should be glad he's not in the office right now! LOL

No problem at all!

It's funny...I thought my exhaust was loud, but yours is WAY louder, especially while driving. I'd imagine wildlife for miles around was ducking for cover as we blasted back up Rt.28 from the dealership!

Thanks for the ride, by the way. I really appreciate it.

I cant wait to get exhaust on mine. Im going to take off my RT's and put on resonated test pipes. Im probably going to go with the Injen straight tip. Anyone interested in a set of RT's?

I've always wondered about folks who run without Cats. I guess for John, here in VA, he justs puts his cats back on the car every two years to pass emissions then takes 'em back off? I personally don't have the equipment to do this, or I might consider it. The RT cats are really a compromise between performance and laziness...They give me a small performance increase, and I stay smog-legal.

How hard was is it to pull the cats off this car? I'd imagine it involves dropping the exhaust based on what I've seen of the underside of this car.

John?

The cat bolts are difficult to get to, but since I replaced the bolts with non-cast iron ones that don't rust, getting the bolts loose shouldn't be too difficult. All you really need is jackstands and a little patience... I will be putting my stock cats on in October for my emissions...

whats the price difference between those two and weight ?

 

[scorpZ]

I don't know the exact weight, i'd say about 25 lbs for each cat, vs. 5 pounds for each test pipe...

The Injen is about $100 - 200 less expensive than the Greddy, and I'm pretty sure they weigh about the same. IIRC, the Injen was about 20lbs. lighter than the stock exhaust...

The link in my OP works again. I had to rebuild my server, so all content was offline for a few days, but it's back. It's kinda slow on the download because it's coming across my broadband connection, so have a little patience.
