cooler pipes for sure. they are known to split. will do ok without a fuel pump and surge tank. I would get a better cooler instead. and I wouldnt be driving around with a dump pipe and cat with no tune! will over boost just had mine done on friday with 355rwkw with cooler, pipes, battery relo, 4inch intake, 60lb injectors and a tune. you should see 300 I would say with the mods u have mentioned
