An SR downpipe and all pre-fabbed exhaust systems are 12" apart. Just enough room for that cat/fake cat.
why would u waste fucking $300 on something that has a name brand? buy an N1 muffler and get custom piping, your car will breath better and just for jeff, look pretty.
Mufflers can't make power. The most efficient mufflers can only employ the same scavenging effect as a header, to help slightly overcome the loss of efficiency introduced into the system as back pressure. Looks isn't a debate here. I gave insight as to how difficult making power in a small motor is. You're the guy that attempts to belittle me, because I attempted to correct the information of implying KA and SR use different exhausts, and a muffler shop setup roxorz.
(fuck mandrel bends
it doesn't matter when you don't have any sharp bends in your system.)
Ask Secret Services why they use 1 piece, mandrel bent piping for everything. From SR downpipes to the 8" intake pipe. Even though the largest bend is about 30*.
Mandrel bending does make a difference. On the exhaust side hot gases molecules maintain their enegy levels until they escape out the tail pipe (enthalpy). The normal OEM wrinkle bends (and crush bends to a slightly lesser extent) reduce the exhaust gas flow(velocity) and energy (molecular) as they move around the bent through your exhaust plimbing. What this eventually means is a "bottle neck" effect in your system. Mandrel bending also reduces the impact of gas flow as it moves throught the system and maintains the scavaging effect. There is a reason SS doesn't use a crush bender, or crush bent piping. There is a reason people try not to make unnecessary welds. This is because physics (fluid dynamics) works. Slight variations in exhaust flow, slight areas of turbulence, bottlenecks, ect. will cause disruptions in flow, actually making you lose power.
If you still aren't convinced, find someone with an s14 and custom muffler-shop exhaust. I'll go to SS, pay for the dyno, and run with my N1 dual, and then another run with the shop exhaust. I'll also bet $50 that there will be a 10-15hp difference.
Anyway, I'm not some arrogant dumbass. I'm an arrogant, knowledgeable person that will help just about anyone. Don't be a tool over 1 correction.
