Coverage and how to read this overview

Counts describe captured discussions, not unique people or a diagnosis. Author identities are not reliably stored. Exact duplicate evidence is counted once across matching discussions; one discussion counts at most once per action/state. Multiple repairs reported together remain a combination. Suggestions and failed attempts do not establish a fix. Matches cover whole discussions and can include related faults, model variants and incomplete threads.

POST 1 / ORIGINAL POSTEROriginal post

Greetings gents, Sorry to bother everyone with another exhaust question thread - however, just curious to see the number of people who have the Fister mod done on their car (whether done by Fister themselves, or getting the bypass done in the same way).... My situation is that I currently have the Fabspeed cold air intake (which I now know isn't doing much except a bit of induction noise), and the Fabspeed Sport Cats (200 cell, I'm pretty sure). So, I've got a bit of noise at WOT, but I'm looking for a bit more rasp and occasion but I don't want ANY drone at cruising. My questions: 1) How long have you had the Fister mod and do you still like it? 2) Did you have the mod then reverted back? 3) Are you running any other exhaust bits with your Fister modification? I just don't want to do it and regret it and have it be "too loud". It's not my daily, but I'm planning a long multi-day road trip and I don't want it to be annoying. Pic for attention -Matt

POST 2Original post

My car came with the Fister mod, it is glorious. When I did the plugs, water pump, etc. I determined it was in fact one done by Fister. My car also came with a hot air intake made by K&N, took that off and went back to a stock air box. Had no effect on power or noise. I would not go back! Do it!

POST 3Original post

Bought my car with the Fister and a no name 200 Cell cross pipe. Added: - IPD Comp plenum + GT3 TB - 997.1 Airbox - Agency Power headers There�s no drone or rasp, sounds fantastic above 4K RPM. I�d never revert because it�s a good compromise in comfort + sound.

POST 4Original post

I had Fisters installed on my car last spring, exhaust is stock otherwise. I love the sound and would do it again in a heartbeat.

POST 6Original post

Sent stock mufflers to Fister three years ago. Love the sound. Bought a pair of used mufflers on the PCA Mart and sent them to Fister. Took off the old ones and sold them on the PCA Mart. Decided on the Fister option because the car came with Sport Mufflers that needed to be replaced and I didn't want to spend that much money.

POST 7Original post

I have the Gundo hack, which is similar, but without the additional features that Fister offers. It sounds what I would expect the stock exhaust to sound like. Check this out if you haven't already: You Tube

I've got the IPD Plenum and GT3 TB as well, but headers are original I think... I should really install the 997.1 airbox I have sitting around... -Matt

POST 9Original post

I had the Fister mod performed locally. I like the sound very much. Docile sounding around town, evil sounding with your foot in it! I have not found a downside. Doug

3.8 or 3.6? Mine is a 3.6 and it�s just for aesthetics, the Rennline carbon intake goes in the car tomorrow.

POST 11Original post

A Fister exhaust was (and still is unless you count the IMS Solution) the only mechanical modification on my 996 when I bought it. I was surprised that it had absolutely no drone on 300+ mile ride home. IMO the Fister has the perfect combination of not bothering my neighbors when I leave the neighborhood but sounding great when I step on the pedal. I�d never revert back to stock

POST 12 / ORIGINAL POSTEROriginal post

The 3.8 airbox - it would match my displacement.

POST 13Original post

I have a 98 3.4 with original mufflers that have had some of the internal baffles removed. I did the oil cap mod inside the air box. I think it sounds glorious inside the cabin and not droney or annoying. That said, I heard my mechanic driving it last week on a brake test and I was less impressed as it drove past. Am genuinely considering the Fister mod on a set of either genuine, or Miltek style stainless mufflers.

POST 14Original post

1999 C4 with a 3.8 , aftermarket headers and x-pipe with Fister Motorsports modified mufflers . She has a glorious bark on acceleration and deceleration and can still be docile when you go easy on the throttle . I am very happy with the results .

POST 15Original post

I went and did the straight pipe approach. Actually sounds great without too much drone and not crazy loud. A lot of folks (at PCA meets) say they like how it sounds, I figured you can buy the straight pipes for $120 and if I didn't like them (not out a lot of money) I could go back to the stock hack approach.

POST 16Original post

I had mine converted by Fister 14 years ago and love every minute of driving with them. 2000 C2 Cab.

POST 17Original post

Had the Gundo hack done at a local shop years ago. No regrets.

POST 18Original post

01 with fister type mod and FVD catless x-pipe. Way too loud for the street. It�s been measured at about 97db at the track. With just the mufflers it was very nice. Here is my friend in his 997 passing me at lime rock last week. My car is the one making all the noise. Instagram

POST 19Original post

Does anyone have a view or experience with comparing the fister mod on a stainless vs mild steel muffler, as in there a noticeable sound improvement either way? Also, with the fister; is there a benefit to having the join piece in an arc shape as opposed to a straight �bridge� from the inlet to the exit pipe? was thinking that if it was more arched, does this improve flow?

POST 20Original post

I have the PSE system. I cannot tell the difference between sport and normal with respect to power. If there is it seems immeasurable.

POST 21Original post

I've had fister mufflers for years. No drone and great sound. I do have FVD catless pipes, so its a bit louder than with just the fisters, but still no drone. I drive the car a lot and they have been great. Fister Sport Exhaust and FVD X-Pipe (youtube.com)

POST 23Original post

Another happy Fister customer, one of first mods I made. Had them ceramic coated, they look and sound great.
