Supersprint Sport

So I just got my Supersprint Sport mufflers. Decided to try and install them myself this afternoon after opening them up and realizing it just bolts together and then looking underneath the car and seeing the OEM exhaust just unbolts. I figured worst that can happen is I mess it up, I already had an appointment on thursday to have my local exhaust shop install them. After and hour and a half with a car jack, a couple truck stands, a ratchet and wrench I had my new exhaust installed. Installation was so easy, I only needed a second hand just to hold the new mufflers in place until I got the first bolts in place. Glad I tried this install myself, I saved at least $200-$300 that I was quoted to have it installed.

Now the fun part, trying it out. Gotta say it sounds great. Idle is a bit loud as these new mufflers have much more bass it tends to resonate just a little bit. They are loud if you stand about 10 feet behind the car. Driving the car sounds really nice though, not loud at all unless you get on it. Still not loud just has a nice sound. Inside the car is quiet while driving. I've only had a chance to take it on a quick 5 minute ride, then I let someone else drive it around the block so I could hear from outside. You definitely hear the car now as compared to stock where you barely hear it. Nice improvement though. I only changed the mufflers, I'd imagine upgrading the rest of the system would sound really sweet with the Supersprints but I would also think it would be too loud. Glad I just did the mufflers, enough to enhance the sound without calling too much attention to it.

I can take some pics, I don't have a video camera though. What I can say is the sound in real life is impossible to get off a computer video. I listened to a lot of youtube vids first before ordering and there's no way to tell it sounds the way it does when you're standing behind the car

I agree about the internet video clips. Plus, I honestly don't care what the car sounds like driving past a camera, I want to know if the sound is livable inside the car (5600 miles already on my E92). This sounds like a great alternative to a full exhaust system though. I really just want the note to be a little deeper, especially down below 4k rpms.

Congrats...nice when an install goes smoothly and is cheap!

I would like to hear your thoughts on the interior sound...droning?

When the engine is cold at idle there is quite a bit. Once it warms up it seems to go away. It's really quiet inside when you're on the gas, but you get a little bit of drone around 1,900 RPM if just barely on the gas like 10% or so, soon as you let off or accelerate more it goes away and is quiet again. I haven't gotten to cruise at high RPM yet since I haven't been on the highway with it installed. Sounds great though on hard acceleration over 3,500.

So I'm starting to think as I grow up having loud exhaust isn't as fun as it used to be. The supersprint sports sounds really good, but to me the thrill has past after the first day. I'm considering unbolting them and selling them to anyone on here if someone is interested? They cost me $2k and I could really use the money instead, since they have less than 2 hours of use on them I would like to get the $2k back for them if anyones interested. This includes the adapters, connecting pipes and bolts necessary for complete cat-back install. If you were considering ordering them I can save you the two - three week wait it takes to get them from the factory. PM me if interested.

maybe, street version was more expensive.... dont' get me wrong, the sports sound sick. I just haven't had a vehicle with exhaust in a long time and am kinda over it.

On second thought after listening to it again today these mufflers do sound pretty badass on the car. I'm thinking I'm just going to keep them. Probably wouldn't do it again on my next car as I'm not so into loud exhaust anymore. But the sound this thing makes when you get on it is really sweet. Maybe just takes me a bit of getting used too.

After going back and forth trying to decide, Supersprints are finally back off the car and OEM is back on. Looking to sell the almost brand new Supersprints with connecting pipes and adapter necessary for easy bolt on installation. Asking $1,800 to ship anywhere in USA.

Sorry,

I was curious about the look and sound on the car. I have the Eissenman sport on order and live in the UK.

It does appear that you are very unhappy with them, off the car is a matter of days ?

I figured the sooner I took them off the closer to new they would be and the easier to resell.
