which exhaust is best?

[itz_alan]

I emailed numerous companies asking about their exhaust systems and apparently i've only found magnaflow to make a cat-back specifically for the 2003 msp. They told me that their exhaust gives the msp a 5.5 hp gain, not impressive.. Does anybody know of any other exhaust systems that give at least 10+ hp for the 2003 msp? There are exhaust systems for the rsx and the wrx that give the cars around 20+ hp, are there any like that for the msp's? If anybody knows which exhaust gives the msp the most power gains, please let me know, along w/ numerous other people who probably have the same question.

Sorry to be an asshole. Try the Search function. This has been beaten to death. Your answer lies elsewhere on this board.

Good luck freeing up tonns of HP with an exhaust. All modds help a little and combine to make a noticeable increase.

like i said i emailed a lot of companies.. there arent any dyno tests or set hp increases on the universal exhausts especially since different cars get different amounts of hp gain. How am i supposed to know which universal exhaust is best? which is why im asking people on the forum? if there are dyno tests on universal exhausts for the msp then let me know plz.. cuz i couldnt find any cept for the ones made for the msp

Please don't just get a universal muffler...

Unless you're running a lot of boost on your GT25R or you've upgraded the turbo; 2.5" piping will be fine. 3" is overkill for the GT25R in most cases. Corksport's systems look promising as they've been a staple to Mazda tuners for years.
