IMO Greddy has the best exhausts for the VQ motors

It can for sure be purchased for less. Just make a few calls and see who is running some deals. I believe I purchased mine for around $1200 shipped about a week after it went on sale from a shop that has since cosed their doors. Keep looking and good luck!

I purchased mine for $1350 from Importedperformance.com

Improtpartspro has it for $1272.00. I love mine, I also have the Berk HFC's in stalled. I had a dyno done and it increased 11 HP, was hoping for more. But I do have a question for some of you reading this thread, When I had my dyno done before install and after I got an increase of 11hp and 9 torque, is it true that if you drive your car for awhile it will increase more due to the map so the engine will get use to this or did they blow smoke up my ***?:rolleyes:

But at the same time I also live in Colorado....altitude make a difference?

I have the same exhaust mod as you plus the stillen G3 intake. I got my HFCs a week after I got the cat-back and the intake. And when I installed them I had a weird feeling as if the car just lost power but I felt the increase after I started driving around a little bit. I think it's just a matter of time then you will feel the power increased. A lot of people told me that the ECu needs some miles to realize the increase in the air flow. But the HFCs are the one I felt as it was installed. I went to drag my car 3 hours later and got 0.3 better than last week

Just in case you didn't know. You first diconnect the battery to reset the ECU (plus due to messing with electrical componets). Install parts. Reconnect battery and let the car run (ideal) for five minutes to allow the ECU to get used to the different air flow. Then you can take it out and run to red line to allow athe ECU adjust to all settings.

I read about that a long time ago. Thanks for the reminder.

I have it and love it too. Sounds great.

One thing to note - this exhaust DOES HAVE SILENCERS BUILT IN to the mufflers. I assume they put it in to meet the legal decible restrictions.

I pulled mine out over the weekend just for fun and it is UNGODLY loud now. Sounds great outside the car but too loud inside. Pretty loud drone from 2700-3200 RPMs with the silencers removed. So while it probably freed up a few more horsepower I'll be putting my silencers back in except for track or show days. With the silencers in it was a very subtle increase in sound in my car. And I have about 85 lbs of sound deadening material from the front footwells all the way to the very back of the car.

But for those of you who happen to like obnoxiously loud cars it's a 10 min job to pull them out and wake up the entire neighborhood.

Thanks for the info, will give that a try.;)

have you noticed a difference in power ?

I might take it to the drag like that :driving:

I didn't really notice much of a difference in power after removing the silencers.

Not really. It's probably freeing up 3-5hp if any. not enough to notice.
