Yeah I've seen those pics before. I can't believe they put that crimp in the exhaust! :dunno:I'm not sure which Genesis this is from, sedan or coupe? But, it is definately restrictive.
I wanna thank bkmania for the pics & Gencoupe.com for finding them.
I've thought about the exhaust tips as well. My thoughts was to maybe make some inserts that a round or oval tip could fit through so as to make it look better.. Who knows it may look ok with some oval tips or maybe someone will come out with a tip just for the coupe.Holy wow, yeah exhaust will def. have to be swapped out regardless, Thing i'm kinda worried about is the factory muffler tips. As they are pretty much molded intot he bumper how the genesis would look with a saw magnaflow oval tip there. (i'm a huge fan of magnaflow mufflers for a custom 3" exhaust) had one on both my DSMs and my tiburon (2.5" single exhaust)
Read the OP, it states that not sure whether exhaust is off of sedan or coupe.I don't know where that exhaust came from, but the exhaust on my 3.8 Track does not have that huge resonator shown in the picture. The piping on my car looks more like the exhaust from RRM shown in one of the posts above.
I just checked the HMA Service web site, and that system is neither from the sedan nor from the coupe. What that pictures shows is the middle section of a 3.8 sedan exhaust system (the part with the huge resonator) bolted to an entire 3.8 coupe exhaust system from the headers back. The picture is not representative of either system.Read the OP, it states that not sure whether exhaust is off of sedan or coupe.
I'm not sure then what it's off of :dunno:, I got the picture a very long time ago from gencoupe who got it from bkmania. Later on a made a thread around Christmas time of that pic alone showing the restriction.I just checked the HMA Service web site, and that system is neither from the sedan nor from the coupe.

Yeah, I've learned alot since the origination of this post & have studied a little regarding what you are talking about. Also looked into the myth of back pressure & started a thread on that as well. This is sorta like when a smaller diameter exhaust can actually increase air flow on a certain set up because it increases velocity therefore causes the exaust gases to be pulled out of the tail pipe quicker. (very simple description).Crimping does not necessarily decrease flow: on the contrary, it can actually increase flow. It's called the Venturi effect. In a Venturi system, gas or liquid leaving the narrowed section has an increased velocity, which pulls more gas or liquid with it.
Here's a link to a description of the Venturi effect:
