Can't speak for the others but RJC pipe looks, fits & breathes well. A very gradual curve puts it tight on the inner well but can be dealt with. Good choice!!!
i think the pipes made now might be a bit better. just for the simple fact is i believe youre not limited to using certain headers. theres a lot of factors that can contribute a dp being tight fit/rubbing-worn body bushings bad front shocks i believe motor mounts..
I run the rjc one and i would buy it again and again. top notch well worth it..
I put one one the wife's T-Type. Great looking, good fit and finish. When the old non-stainless TH DP gives out on the GN, I will be replacing it with the RJC...
