headers for sidepipes are different. Some road race headers are very long and pass where the sidepipes need to connect. 3" sidepipes are loud. No X pipe also makes them loud
What kind of headers do you have and what size

make sure the new headers match the performance of your engine

the street dominator intake is horrible. Get a scoop and edelbrock rpm dual plane, or step up everything in the engine then you can use a single plane
