Benefits of dual exhaust pipes? by stanwelks

Are there any benefit(s) of the 2 exhaust pipes from a performance stand point?
 
Any other benefits?
 
Thanks.

I think it's only for looks. I think with four bangers, dual exhausts are kind superfluous.

I'm no expert, but dual-exhaust reduces back-pressure on the engine, which adds some extra "crispness" or power. In every-day driving, I'd doubt that the dual-exhaust makes one bit of difference. But, rev that 4-cyl up like it's made to do and drive it like a sports sedan, and, yes, I'm pretty sure it makes a difference. Your best bet is to ask this question about the TSX at Acurazine or a more general question about high-compression, long-stroke 4-cyl engines at a more technically inclined enthusiast board.

I have (my wife really has) a 06 with 5AT. I was checking out Comptech web site and I liked the supercharger kit for the TSX (http://www.comptechusa.com/store/page5.html). They don’t have a kit available yet for the 06 models. Do any members have the supercharge kit on their 04/05 TSX’s? I wanted to find out (especially from 5AT owners):
- Does it void the original manufacturer warranty?
- Any additional wear/tear/Maint on the drive train (transmission, CV boots, half shafts, etc.)
- Minor or major gas mileage decrease while driving normally (under 3,000 rpm highway cruise).
- Any other Maint issues and cost for routine Maint for the supercharger?
- Is the supercharger worth the 4k+labor in your opinion?
 
I was planning on adding CAI, headers, exhaust and Hondata chip reflash to the car next summer. I figure for an extra 2k, I could replace the above with a supercharger and get real noticeable hp/torque gains. Just want to find out the long-term pit falls of the supercharger.
 
Thank for the input.

Nobody's really had their TSX SC'd long enough to consider it longterm yet. I'd link you to a site with a lot of info, but that's not allowed here. Try Googling acurazine. Lot's of good info there on the Comptech SC.
 
Keep in mind that Hondata still has to relflash the ECU to map it for the supercharger. The people I've talked to who have it have been really happy. Not sure about the warranty issue. Try the search.

I checked out the information at Acurazine before posting here. I did not find and long-term supercharger feedback or any information on warranties at Acurazine. The 4-5k for the supercharger/CAI/Hearder/exhaust might be better spent on a downpayment on a 08 TSX (assuming the same engine from the RDX is used). I'm going to keep the 06 TSX for a while and pass it down to my son for his 1st ride (9 years old now). I will still look for any information on supercharged TSX in any forums.

I'm almost sure a 3rd party supercharger would void the warranty. If you wanted/needed that much power, you should have gotten the TL which you could have for what you'll pay for the supercharger.

Telling a TSX owner if you want more power you should get a TL. It is like telling a TL owner to buy a RL if you want more power. BLASPHEMY! Say three hail Acura’s and make the sign of an A three times across your chest!
 
All of these cars are similar but have different characteristics in styling, handling, features, and target demographics. I’ve looked at the TL and I felt like I just drove the car. When I was test driving the TSX, it really seemed like I was part of the car and I felt the road instead of just driving on it. The TSX can handle the extra power and push the “fun to drive factor” from an 8 to border-line 11 (I have a 5AT). I love the 2.4L engine high redline power, mid-range torque, and mpg ($3.05 a gallon for 91 octane in NM). I also drive any where from 5,000 ft to 7,000 ft elevation and some extra power would come in handy when needed.
 
Most TSX owner’s think about CAI/headers/free flowing exhaust/hondata reflash to release a few more trapped ponies from the 2.4L engine. We will spend 1-2k just to get and extra 5-15hp compared to spending 4k for 45-55hp with a supercharger. With most TSX owners, it’s not just about the power but the total package. For my driving habits, a supercharger would improve the TSX's total package.

Unfortunately, short of supercharging, there's not much you can do get get more torque out of a 2.4 liter engine. And torque is where the TSX is lacking, more so than hp. Maybe you should have bought a BMW 3 series

I'm not too crazy about BMW. I'm planning on keeping this car a long time and pass it down to my son for his first ride 7 years down the road. I know my cost for ownership would be far less in a TSX compared to a BMW after 7-8 years.
