Hi all
Thinking of removing the 3rd cat on my GS300. I had a full Tony Banks exhaust fitted from the the downpipe with a brand new 3rd cat. I went for the mid-sport option however I feel like it's a bit muffled on idle and looses the sound on higher RPMs, so debating on removing the 3rd cat.
What are the opinions on this? Will it change the sound drastically? Couldn't really find many posts of people who did this so asking for opinions.
As far as I am aware it won't throw any errors as the o2 sensor is pre 3rd cat.
Thanks

Hi everyone
I took my newly purchased GS300 MK2 up to Scotland and for a road trip and it did amazing except for loosing one of the rear exhausts on day one 😅 I took off the exhausts and did 2000 miles with no problems. I love the sound because it's a little growly but nothing to obnoxious - no drone inside the cabin just a little nice rumble.
Booked a backbox delete at a Flowtech in Dagenham in two weeks however reading up on backbox deletes ( muffler delete ) there are a lot of mixed opinions. Some people are saying that it sounds great with no issues, others are complaining about the drone at low RPMs. Therefore I need some advice on what option to go for. Backbox delete will cost around £200. Was looking at different options however they're a bit more costly everywhere else - new backboxes £400, backboxes + Y pipe £600-£1000. Was initially set to do it with Tony Banks however can't justify the 4-5h drive.
What's your opinion or experience on a backbox delete on a GS300 MK2?
Thanks

MOT shouldn't be a problem. I'm more debating whether it's worth deleting it for better sound. Do you think it will make it louder/deeper or not much difference to what I have now?
