I put a Borla on my RX7. Sure i got more HP. The only problem was I had to keep the revs waay up to get the few HP. Felt like a turbo below 4K. the lack of backpressure killed low end torque and made around town driving much more of a chore.

Hi!
Back pressure is bad on all engine !
It's written in any good books...
The velocity is important on NA engine, an exhaust too
big and you will lose velocity and HP.
On turbo engine the bigger the better because you don't
need any velocity.
I invented nothing, this is not my opinion it's a FACT.
Campeck, nice muffler, take pics once it's installed and a video with sound would be great !

whether or not you go big depends on where you spend your time in the power band
if you're never below 3500, i would go with a straight pipe all the way
its a compromise, and like someone else pointed out Camshaft selection is KEY

i was actually thinking a cam grind and remake with more overlap would defiantley yeild more power due to the complete lack of it on the US engines. or is it all? doesnt matter.
it looks awesome..its LOUD it has a ricey undertone( i can deal with it) and it does seem to have killed some power. wich is why i was thinking of getting a cam with some serious overlap and a maxtronic. muahahah!!!
ill have pics and a vid in 2 min. stay tuned!
