Dual exhaust for Integra? - Honda Forum / Acura Forum

Hey guys, I got a black widow body kit and on the rear it is molded for 2 mufflers, one on each side. Why would they do this for and Inline 4 engine, that comes with a single exhaust system? So, I thought about it and since I'm going turbo, I thought adding another muffler with custom piping on the other side would free up some more exhaust flow (I already have a 2.5" system). Is this a bad idea for an Inline 4 engine, even though it will be turbocharged, or should I just close up the hole on the other side, and stick with single exhaust. I don't want it to look ricey. What do you guys think. Thanks.

Yeah, I would keep it single, anything else just wouldn't look right.

I have been thinking about duals aswell. I have to replace all the pipes when I go turbo so I was going to split into 2 pipes after the cat. 3 or 2.5" into two 2" pipes coming out the back. Reason for this is to avoid purchasing a new muffler. I will just put tips on the back. Nothing flashy or muscle carish.

I have heard that you are ruining performance by a dual tail setup that is not designed properly.

I see. Well I thought it would actually look good since the rear body was made for it, it actually looks pretty weird with only one muffler coming out and a big hole on the other side

I guess I should just fill in the other hole. Dammit why would they put the hole there in the first place.
I thought the less back pressure, the better for turbo? Isn't it more about design for naturally aspirated?

If I were you I would go with
DP - High-flow cat- Full cat-back exaust. And please don't just put tips on the back, go get a true cat-back exaust system.
