Lotus Esprit S4 S4s Sport 300 T304 stainless steel sports exhaust
Surely straight pipe has been tried. Is it obnoxious;y loud?
is that a V8?I have straight pipes and Flowmaster cats, and I don't like it. It doesn't give you that growl other exhausts do
Very cool. A sound clip would be appreciated by even those of us who don't have an Esprit.So, I have a 98 V8 and had an issue I thought with one of my Cats. I do have a 4 post storage lift, so once I figured out how to take the rear trunk liner out I decided it was time to inspect the Cats. I thought one was clogged, as I had limited exhaust coming out of one side, but the car still seemed to run fine. I also had bought a really cool muffler delete setup from a member here in the states and more on that in a second. So I remove the existing muffler and also the splitter that goes between the rear two tail pipes. I weighed the assembly / muffler and I think it was 63 lbs or 28.6 kilos. Pretty heavy, so now I removed the 1st Cat and someone before I owned the car had modified the Cat and there was nothing in it at all. Just a hollowed out tube, but it still looked like a normal Cat. I then removed the 2nd Cat and it was the issue with broken catalyst in it and I assume clogged. It was unclogged lets say and retained in the next set up I will describe. So this brings me to the setup I bought from a Lotus Forum member here in the states. It was a complete muffler delete setup. It was comprised of 2 pipes, one for each side and it came out in the stock location. One difference is that instead of it having a single exhaust tip on each side it has dual exhaust tips on each side that look very close to what the stock exhaust looked like. It also came with a shortened splitter the piece that goes in between the tailpipes. These tail pipes are mounted directly to the Cats. So now with this setup I basically have no Cats and No Mufflers. At first I thought it was too loud, but now I do not. The turbos muffle the sound a bit and here are the positives. Probably lost 63 lbs or so in the process, which is like adding 7+ horsepower. The turbos spool up much quicker, meaning that if I now floor it in 1st gear my car will spin the rear tires pretty violently. Car is definitely quicker to respond to gas pedal, meaning as I give gas the turbos spool up quicker and I get a quicker response and quicker car. I did put in new O2 sensors when I did this and put O2 spacers in, so as to help with not getting Cel codes. I think the sound is as good as you will get out of this motor. Maybe I will take a picture and post the underneath exhaust I think you will find it interesting.
I will do a sound clip......once I finish with my Radiator install............they might find a cure for Coronovirus by the time I finish with the Radiator install. What a challenge!!!!Very cool. A sound clip would be appreciated by even those of us who don't have an Esprit.
Just curious what was the outcome on the exhaust install? Any pics, video, or sound clips?I took some pictures today of my exhaust and will try to upload tomorrow. Once I get my radiator installed I will do a sound clip. I made some good progress today on the radiator .
Let me see what I can do to show the exhaust and try and post a clip of it running. It definitely has pops at time and is knarley sounding. It might be too loud for some, but really not for me. I have a guy down the street, which I might have said, so excuse me if I have, that has a 570S McLaren and guess who's car his kid thinks sounds better? I think that whatever decision is made that if you can Cat delete your car you will see a quicker spool up of the turbo and a quicker response. The car feels lighter and more responsive to part throttle inputs. There are certainly better authority's on here than myself.........but I certainly know that the car feels more responsive and quicker.Just curious what was the outcome on the exhaust install? Any pics, video, or sound clips?
