Hooker long tubes tips??

i have hooker super comps on one duster and tti on my other duster the hookers fit perect and you can work on the starter . the tti's fit perfect also but it is near impossable to work on the starter . i have zero complaints with my hookers 15 years and the same exhaust and collector gaskets and no leaks. and i paid alot more than 75 bucks for them 15 years ago .
