Hi there!
I'm new here and this is my first post. I'm from Kiev, Ukraine (it's Central/Eastern Europe)So I apologize for my English
.
Owing a 95 Samurai, 3.5 Calmini Lift Kit, 30" BFG AT's, modified intake with deeply modified Solex carb on it, K&N air filter in stock place, MSD Blaster Coil 2 Off-Road + MSD 8.5 Wires + Denso Iridium IW16 plugs, Calmini's Tri-Y header and custom selfmade cat-back after it, 4.89 Petroworks T-case kit, AVM 538 hubs.
Well backing to the topic. It's all started after I've rebuilt my engine, I'd noticed that engine can't breath properly, so I started thinking of getting a new exhaust system. My friend brought me Calmini's header from US as a present for New Year. Therefore the header has a 2" out I ordered Cherry Bomb Glass-packed muffler (

I know that if I did all the way through 2" pipe I'd lack some torque in low-to-mid rpms (1000-1800) so glass-pack took it's place just after header and then I reduced inner pipe diameter from 2" to 45mm with two couplers(51mm -> 48mm and 48mm -> 45mm) to keep torque line smooth, at the end of the system I've installed small resonator (45mm also) to make less noise.
What I get?
I get a good sounding, all the way straight-through exhaust system. Power gain is about 12-15% (~10 bhp) + better mileage(? fuel economy).
Will post som pics later.
