I am currently in the market for a aftermarket test pipe for my EVO X. Are they worth the money for the performance gains? My car made 323whp/322 tq on Buschur Mustang Dyno (Heart Break Dyno) and from what I was told dont even give you much of a gain in power. I also have the Buschur Cross Flow Quiet Catback and its definatly what they say it is when they say Quiet. Sounds really good but I want it a little louder. So who has noticed a performance or sound difference when adding a test pipe? I am looking at the MAP Test pipe. Also are you guys getting check engine lights?

 

Yes it's a good mod, yes you'll gain power, yes your car will sound meaner, and any decent tuner will be able to disable the CEL.

 

Sound and performance gains are all there. However, if I had it to do over again I would have gotten a high flow cat. I have no desire to make car washing and detailing my career so the soot that builds up all over the trunk, lid, and wing grates on my nerves. If you wash your car regularly it isn't a problem, I just happen to have the color that looks completely clean from afar, even when filthy.

 

I believe ur sig is a PB EVO X I have the same color. How bad is the soot I wash the car at least once a week and it really never sees rain or snow. The wifey drives it mostly so WOT pulls are not even in question with her lol.

 

Can this be turned off with ECUFlash?

 

ECUFlash or an Accessport

 

Mine is GG, if you wash once a month it wouldn't get too bad at all. I wash mine about 6 times a year, garage kept at home and work.

 

im running testpipe on PB. I have to wash my license plate once a month or it almost becomes unreadable LOL!! But you can't see the dirtiness like you can with the other colors. I love the testpipe. The sound and power is great.

 

Dude, with the Buschur SS crossflow CBE, I still have intense carbon/soot build-up on the rear of my car. My exhaust sounds pretty good but I am also doing an upgrade to a downpipe w/ test pipe. I'm loud and obnoxious though, lol.

 

Holy Crap! You said ECUflash before AP, lol

On a serious note...

Here is no Test pipe vs. Test pipe.

No TP


TP installed (gains throughout)


Testpipe ftw!

 

I'm debating on high flow cat, resonated test pipe or test pipe once I get my AMS widemouth in 2 weeks..do they have similar gain? I want to keep the current noise level but more power lol.. Any suggestions?

 

If you don't get emission tested, go testpipe. If you care about noise, get a resonated testpipe

 

Agreed.

 

You forget I have a car tuned on each sitting in my garage

 

The subaru?
