so after getting my stock up pipe welded... 3 times... and it just keeps breaking ive come to the conclusion that I should just spend the money and buy a new one... Im not exactly able to buy like a 600$ exhaust system and its starting to go. I found a set of headers with the up pipe on ebay for 100$... I understand that it probably isnt the best quality and that the headers suposedly give no gain, But I also question why people would buy them if they had no gain... so I guess my question is whats ur advice on this little set up and could a bigger turbo possibly fit on my stock set up someday??
