Anybody..........I'm thinking of going with a set of PRTs for my '98. Initially, I put on the AA mod, but didn't like the popping out the exhaust durring decelleration. So, I installed a x-pipe. Well, the x-pipe got rid of the popping, but it also quited down the exhaust to much. I'm not looking for a loud "hey look at me" sound. Just something deeper and meaner. The PRTs and a x-pipe sounds like the ticket.
Fortunately, Doug Rippie Motorsports is less than a half hour from me and they are willing to install the PRTs. If I don't like the PRTs, Doug Rippie will remove the PRTs and refund my money (minus the $75 labor charge, of course.)
I read somewhere that, on a '98, the PRTs caused resonance. I thought the whole idea behind the PRTs was to reduce the resonance. What have been your experiences? Any help will be apprecieated. My appointment with Doug Rippie is for Monday the 22nd. Thanks.
Moderators........Obviously, I wish the new format had spellcheck. :cuss
Two of my closest friends had PRT's on their 99's.... they swore by them till I pointed out their very obvious resonance at the 1700 /2000 rpm range.. They made every excuse in the book..they both rode in my car several times..without any debate on the sound of my car... after a while they both came around ... One guy sold his PRT's for 300 dollars and got Corsa Indies.. the other guy tried to get four hundred for his but couldnt.. when my buddy Steve got his Corsa's Mike gave his PRT's away for 250 dollars and ordered the Corsa's... now they bad mouth the PRT's just like I do.. Problem with them is everyone who has them except the guys with the pre cats.. say they have no resonanace.. but you have to ignore the drone sound at 60 miles an hour like it isnt there..But believe me .. it is there..

Re: B&B PRTs on a '98 (98-C5)
I have a 98 vert with bassani x pipe and prts and it rocks! Nice deep throaty idle (doesn't sound like a motorboat idling like the CORSA Indys), resonance not bad at all and all out ***** when you punch it! Will give you the best muscle car sound than any other mufflers out there IMHO. CORSA Indy's sound good at WOT also but Corsas sound more like an etoxic sports car and PRTs more like American Muscle! :D Can't go wrong with this set up but the best way to make sure is to find someone in your area who has prt's and see for yourself b/f pulling the trriger.
It's best to hear them, for yourself, on ANY exhaust, both inside and out before you buy. That is not always possible. One persons 'resonance' isn't always anothers. Some guys that have ridden with me as me if my Corsa have 'resonance', which they don't, their sound is just more noticeable than stock, which I wanted.:)
The PRT issues with their 'spoons' inside the mufflers, have been fixed according to B&B and we have not had any issues with customer problems concerning this matter since the problem was found and fixed and announced here on the Forum many months ago, by B&B.
PRT's are aggressive and people love that. They are also lighter than your stock system. Only 8 lbs heavier than the stock Ti system on a Z06.(That's about a meal and a half on RAT:))
And Shawn, if you have an issue for a customers car or your car, you can call Mike Ryan at B&B to discuss it, he's great to deal with. I can shoot you the number if you need it.
Evil-Twin.......Thanks for responding. Your friends that had the resonance problem with the PRTs, are they forum members? If so, I'd be interested in hearing more from them. Again, thanks.
RAT..........PRT=Purge Resonance Technology. That's what I thought, too.
RG...........Will you check with Steve at TTS to see if I need to get my Powerloader reprogramed for the PRTs? Steve programed my Powerloader for the AA mod and no x-pipe. Although I had a x-pipe at the time, something got screwed up and the Powerloader was programed for no x-pipe. I called Steve before installing the Powerloader and he said to go ahead and if I start "throwing codes" or the car does not run okay, he will reprogram the Powerloader for the x-pipe. My concern now is that going with the new PRTs and a x-pipe, do I need to have Steve reprogram the Powerloader? I left a message for Steve yesterday, but he has yet to get back to me.
Also, you and RAT mentioned that the earlier PRTs had a resonance problem, but now it's fixed. Are the PRTs date stamped? If so, where and at what date forward did they fix the resonance problem?
I put PRT"s on my 01 MN6 in June. At first, they had a slight "droning" (yeah, I guess some might call it resonance, but I associate resonance with a "warbling" sound). Even then it was so minor I was not bothered by it. It is totally gone now (the carbon build-up after about 1000 miles helps). I frequently drive 60MPH in sixth gear, which is the worst possible case. Trust me, it's gone.
Anyone want to come to Houston, I'd be glad to take you for a ride. If you think my car "resonates", I'll buy you dinner!
One man's resonance is another man's sweet sound. You are better off hearing it yourself. You can get a million opinions, and the opinions are like a-holes, everybody has one. :D
I have had the PRTs for a few months now and they are awesome. The WOT sound is tremendous (considerably deeper and louder than the Indys in my opinion). There is a slight drone at very low RPM cruising that I would not call resonance because it doesn't bother me one bit. It is just louder than stock. Get them, you will love'em! :yesnod:

resonace not bad at all I had to highlight this quote.. this what my two best friends would say.. They justified their purchase in their mind by saying it wasnt bad.. like this guy.. to even mention that there is resonance.. tells the story..
98-C5 I have the PRT's on my 98 M6. It does have a slight resonance in the 1500-2000 rpm range. It is not that bad & I can live with it. Since you have an A4, rpm's will be different than mine. At 2500 it has a noticeable resonance. However, I feel the PRT is by FAR the best sounding system available. To me, the corsas sound like you have a 6 cylinder under the hood. I agree the best thing for you to do would be to drive an A4 with PRT's & Corsas. Good luck- SCOTT
maroon94...........Thanks for your input. Part of the reason I am considering the PRTs is because DRM recommends them. Frankly, DRM knows what they are doing. If DRM wanted to sell Corsas, they would.
So, bottom line, I guess, is that for a deeper muscle sound, I'll have to put up with some resonance around 2K RPMs. Incedently, with the Powerloader, if the RPMs drop below 2K, the tranny down shifts anyway.
I do like the comment that, after 1K miles, the resonance goes away. Not sure if this is caused by carbon build up (in my ears and/or the mufflers) or just getting accustomed to the sound.

GREAT CHOICE!.. The PRTS BLow Away the competition in both sounds, looks and performance.

I don't blame you for the comment that I may just be getting used to it, but I'm quite sure that is not the case. They are noticably quieter, and B & B has said all along that this is the case (the carbon issue).
You can only lose $75. I don't mean to imply that's nothing, but is is a nice insurance policy. I'd be very interested if you put them on as to what you think. This is a continuously hot topic.
There is always a few sets of used PRT's on the C5 parts for sale forum... you never see Corsa's for sale.. I just went to the C5 used part forum.. there are two sets on there right now Oct 17.. for sale.... that might tell you something..
Evil-Twin..........Once again, thanks for your input. It's good to see somebody with a not "these things are the greatest thing since slice bread" opnion.

Correct me if I am wrong, but arn't todays ads for the Route 66s and not the PRTs? From what I've read, the Route 66s and the PRTs are VERY different animals. Here is the links to the posts:
