So I've been on youtube a lot and noticed a couple guys posted up their vids of their Evo with a 3" straight pipe exhaust...and I'm wondering whether there are benefits to this? or will it hurt performance?

Ive searched here and my question isnt really answered...

personally I LOVE IT and I WANT IT...but will it hurt to have it?

and I know a bunch of you are saying stuff like "oh the cops are gonna love you" and "youre a ricer" or "your neighbors are gonna hate you"...but lets put that bs aside and just answer the question.




Heres some vids for reference:

and hopefully the guys that posted those vids are on here and can chime in...i know for sure the aspen green evo is on here...lol hes the reason i looked into this...

so...
if you're reading this. YOUR CAR IS BADASS!

 

Apparently you didn't search very hard.

A test pipe will yield performance gains over a cat or hi-flow cat.

There are benefits to both though depending on what you are looking for.

 

I have a straight 3" TBE with a test pipe and muffler. Sounds great. But fairly loud. No emissions laws here in Alabama so that's not a hassle.

My setup is slightly different from what you are asking but...

Someone....somewhere will always give you flak about how loud it is. My neighbors haven't said anything to me yet (either due to them not being able to hear -- being old...or because they aren't confrontational.)

Performance gains. Simple as that.

It will attract attention but not necessarily the only reason from a cop's standpoint. That's mostly speed.

Ricer? Who cares if it's not outlandish and as long as it's functional and beneficial.

You'll be fine.

 

My friend had one of these on his GSX. It was fun as hell to drive and annoy people but did attract a lot of cops. Eventually he got a muffler.

 

He is not asking about "test pipes" He is asking about an exhaust with just a complete 3" piping. Meaning an exhaust system that does not have any mufflers or resonators. Just 3" tubing all the way through.

And to the original person, it will not hurt anything.

 

THANK YOU FOR READING IT PROPERLY!

and thanks for the answer...

hoping to get more people to chime in on this.

 

apparently you should read the post more clearly. im talking about a STRAIGHT PIPE. not a TEST PIPE.

BluEVOIX explained this already though...

 

Yea i realized that after I posted it. Although a lot of people I know call a test pipe a straight pipe thats why I was confused.

 

i gotta say its cool as all hell, sure there are performance benefits.. but sit in a car like that for an extended drive.. ugh it never bothered me but plenty of my friends get sick of strait pipes. omfg especially one year when we drove to vt.. people where dieing to get outa my friends car and into my subaru.. lol

 

oh if i were to do this i was planning on turning my current TBE into a straight pipe by getting V-Band setup going where the "axle back" bolts up...id cut those flanges off...turn it into a v-band and that way i can switch it on the fly...lol

 

Did it for a week. Wont do it ever again. The car sounds like crap with a 3" straight pipe, drones, and is painfully loud at WOT, and I doubt the gains are THAT great over a good high flow muffler. Definitely not worth worth the trade in sound anyway.

 

Ran 3 inch piping with just a hfc and it was perfect then went to a test pipe and while it sounded very mean, it was too loud. I had to do a 6 hour drive and I felt like I was at a rock concert for 6 hours when I got out.

 

thanks for the responses!

im not too worried about driving long distance with it...as im probably gonna custom make a different setup with v-band clamps for on-the-fly changing...

 

What my concern's about this is I've heard that you need some sort of back pressure for the turbo to spool quickly. With this sort of setup I would think it would be laggy... NO ?
