There'* been alot of talk about that around here. What I've heard is that there isn't one, but a couple guys are looking at creating and selling one. There are kits for the GP, but they obviously won't fit, but you might want to look and see what diameter, cat, and muff they used, then do your own custom system. Most places would probably do this for you for 2 or 3 hundred. I've had it done on 2 other FWD cars in the past, using a hi flow cat and a turbomax muff. It was worth it.

I really don't know if there is any for the Bonnie.. as far as I know you'll have to custom make it either through a shop or with some calculations, measuring tape, and some time to fine all the right pipes and bends

Yeah but it still won't compare with a direct bolt-on

True indeed that it ain't as good as a direct bolt on.. but the real main difference is that with a direct bolt on.. there is less joins.. and somebody already did the math for it. Performance I do not think will suffer even if you took it into a shop for a custom Mandral bend system, or did it at home ( as long as you get mendral bent bends )

I am only 19 years old and I have taken apart and rebuilt a 1986 Monte Carlo SS 8 times . It'* just a piece of mind that you get from direct bolt on than with custom made . And if it is direct-bolt-on it is also going to be mandrel bent which provides a more even flow . Be sides there can be a lot of human error on custom made exhaust. But thanks for your help , maybe you can use all your resources to find one .One more thing . If i go with custom , which muffler do i go with?

There are some companies that will make you one that will work perfectly, but But the cost is not low. You would be better off finding a local shop that you trust and work with them to make your own. Sounds like you knew all this already though.
