bluestyle55,

Actually, I'm starting to get used to the sound now. I almost went back to the shop today to have the stock cats put back on but I think I'm going to give it a little more time. At idle the car sounds almost stock. At cruise with little or no load it is barely louder than stock.

When you accelerate gradually it sounds FANTASTIC! When you accelerate hard it sounds booming in the cockpit, even with the windows up.

My only other concern is the CEL. It came on after about 97 miles. I had them stuff steel wool into the extended bungs but I guess it wasn't enough. I'm going to contact Uprev on monday because I'm of the understanding that when they flash the ECU during tuning, that they can disable the rear O2 sensor. If I can confirm that this will eliminate the CEL permanently AND still allow the car to pass inspection here in Texas, then I will probably keep the setup the way that it is. For the moment, we don't have a tailpipe emission test here in San Antonio.

After driving it for about 175 miles now, it seems that either I'm getting more used to the tone, or it is mellowing just a little. I can honestly say that this thing is not as loud as my Evo IX was with bigger turbo, ported manifold and full 3" exhaust. I guess I just had been away from the car scene (2 years..) that my ears had gotten a little sensitive....

So, to answer your question, NO, the car is only really loud at WOT. Normal, conservative driving yields very reasonable volume and tone with the test pipes and the catback.

Hope that helps!

Tony

yea, I'm getting CELs on long drives now myself. Fortunately, I have a scan gauge and just reset it.

Well, I called Uprev today and they were able to confirm that the ECU flash that they do will eliminate the rear O2 sensor reading. I just have to decide on what other mods I plan to do before having this done. The Osiris flash and dyno time are not a cheap date.

I think I'm going to try it with just the catback. I'm sure that it will be quite different as far as overall volume is concerned. The thing sounds great, but just a little too much for these 47 year old ears with the test pipes.

Just a note, at 93 miles after install I finally threw the CEL. That was with steel wool inserted into extended bungs on the test pipes... oh well.... live and learn.

Looks like I might have some Berk Test pipes with a couple of days use up for sale pretty soon!

any drone at all? or around the 2K rpm range?

tcarretti 12-18-2009 04:46 PM

Actually, they sound really good even with the test pipes. There is absolutely NO rasp whatsover. There might be a little drone, but I'm comaring to what my Evo IX with full 3 inch exhaust from the manifold sounded like. This is much more refined. Granted, when you are on throttle and there is more than a little load on the engine, it sounds aggressive, but as for drone I really can't say it has much if any.

Driving 65-75 miles per hour on the highway is VERY comfortable. I was surprised...

Hope that helps,

Tony
