Roughhouse exhaust

[suzracin71]

Recently put a nuraku 70 kit on and the exhaust felt extra heavy so I cut open the back and found it looked plugged so I removed it welded back together and it’s having issues with running at idle not sure if it needs more back pressure… had a 70 kit on it that made it right at 3000mi Any help would be appreciated

just replace it with a street pipe or expansion pipe you will be so much happier the stock pipe is designed to keep rpms down run a pollution control set up and is very heavy
