Exhaust Recommendation for 90' 7M-GTE

Arlo444 · 03-28-2010, 03:45 AM

First let me say these forums have been a great source of valuable information. I am in need of exhaust recommendations for my daughter's 90' 7M-GTE turbo. A "friend" replaced the stock down pipe with an aftermarket 3" pipe and removed the front cat. From there it's stock to the rear cat then cat back is 3" HKS. The problem is it fails NOx inspection here in Texas. I've confirmed no vacuum leaks, checked EGR, VSV and recently performed tune up. Need to get it road legal but still want the performance. Suggestions?
