Exhaust Dilemma

[NFSR33]

ok...i drive a non turbo 33 (insurance reasons, not by choice )

i just put a 2.25inch exhaust system (catback) with a 4" cannon on the end

now the problem, although it sounds so frickin good, im losing performance

im guessing perhaps its coz i dont have any back pressure bcoz the cannon tip is bigger than the exhaust size?

correct me if im wrong....

but interestingly enough, when i put the silencer on, i gain the performance, but it sounds terrible

is there a middle option where i can have great sound without losing performance

was personally thinking of keepin the same 2.25inch piping, but replacing the cannon with a twin tip (2inch) cannon

any feedback would be much appreciated especially if uv ben in the same position as me....

no buy a turbo comments plz...haha, i already know i need one....

Hey, I have an R33 non turbo with a double barrel (I assume 2 inch) exhaust, and it sounds awesome. It's deep and throaty (without being ridiculously loud) in the low revs, or when idling. After about 4000revs though it gets this slightly higher pitched ring which does get ridiculously loud in the higher revs.

Sounds good whilst cruising around, without being a cop magnet, but sound really finely tuned when given a good thrashing.

I'll have a look at the brand when I get home.
