I'm looking into purchasing trents twins or maybe even some triples in the near future. I am running ATS manifolds and up pipes which are quit a bit bigger that the stock ones. My question is will the downpipe or downpipes (triple kit) have any clearance issues with the ATS manifolds/up pipes? any turbo mounting issues? Can I still run fender liners with the triples? Being in New England I need the to keep sand and salt out.
