Is it just me.......

Or does the Redline/GXP sound a lot better with a straight pipe exhaust then ANY Honda 4 banger ive ever heard? It might just be the design and the fact that its turbo but it doesnt seem to have that Horrible Rattle/Pissed off bumblebee sound of the Honda's. I was just on SOLO's site and listened to their Street Race setup on the Solstice and wow does it sound fantastic considering its a 4 banger.

The turbo muffles the sound so basically every 4cyl turbo car sounds good, its really hard to make it sound bad.

nick112207 · 07-15-2008, 09:21 PM

ah ok thought maybe that was why wasnt sure. because i know every 4 banger around here sounds like crap. Only good sounding Honda is the NSX thats owned by a kid that went to my school but thats a V6 not a 4 banger. On a side note i was curious about running a stright pipe made me think about.

I'm wondering if anyone has tried a setup i'm thinking about. It would be a SOLO highflow cat, Westers Tune, and an Electronic cutout either right after the CAT or right before the Muffler (whichever spot would give the best performance gain). I'm thinking this would be the ultimate Sleeper GXP/Redline because youve got the CAT and Tune but with the Stock exhaust, so put in the cutout and you have the Stock exhaust but a way to quickly switch over to an Unrestricted Exhaust.

Do you think it would throw the same HP and TQ numbers as say a similiar setup Minus the Cutout and running a Magnaflow or Solo exhaust system?

Yes i did search and it was just questions about what size the pipe needed to run it would be and stuff like that, no actual performance talk.

Cut outs sound like crap when wide open but its most certainly good for performance. N/A 4bangers need backpressure, Turbo 4bangers do not need the backpressure. If you want the performance and good sound then get a 3" Turboback exhaust system.

IronMan2003 · 07-16-2008, 06:15 PM

I also forgot to say Turbos are considered to do the job of a muffler. So legally you don't need one. That's why Neon SRT-4s come stock without mufflers and have 2 resonators in place.

nick112207 · 07-17-2008, 12:12 AM

Well but see i dont want a exhaust system that is loud all the time. I'd like one that is just loud when i want it to be. Hence considering keepin the stock exhaust and just putting on an electric cutout.

People have suggested putting it directly on the downpipe, but i was wondering if without a tune that tells the engine to not read or ignore the o2 sensors around the cat, if putting it on the downpipe wouldnt cause it to throw a code when you open it?

I'm also kinda curious and i asked on the Solstice side but never got a real answer, if i got a westers tune, a SOLO highflow cat, then put a cutout right after the cat but still ran the stock muffler, if when i opened up the cutout would i be making the same Horsepower if not more than say a car with a Westers tune, highflow cat, and a magnaflow or Solo mach exhaust?

If you want to keep the stock exhaust and get a cut out. More then likey the best route and more then likely the only option is to buy a cutout then go to an exhaust shop and say you want a 3" Downpipe that connects to the cutout & your stock exhaust.

If you get another cat it will more then likely make the stock exhaust louder. Which goes against what you describe as wanting a Loud on/off option.

No doubt want the cut out before the cat. After would be pointless. You just want the cutout to act as an open downpipe, completely restriction free.

As long as the complete system is not restrictive and a true 3" system front to back then it should be same as a cutout.

You most defiantly won't be making "MORE" HP with an exhaust system then just running dump pipe or cutout. The most efficiency comes from no restrictions on a turbo. The HP #s should be the same if the exhaust system is trully a non restrictive 3" system. If not then no more then a couple hp loss. Not noticible enough.... but if its restrictive you will lose hp compared to an open dump pipe and/or cutout.

nick112207 · 07-18-2008, 03:51 PM

yeah thats what i thought. i was guessing the HP gains would probably be comparable to someone with a westers tune, highflow cat, and a Solo street race exhaust (the one with no muffler just straight pipe).

But my problem with putting it before the cat would then be i'd have the cat throwing codes. Wouldnt i need a custom tune of some sort that would allow the ECU to ignore the O2 sensors?

IronMan2003 · 07-19-2008, 07:40 PM

Nah your're not going to gain more hp then a good tune but it is most defiantly the best supportive mod/the base for any real mods.
You will gain hp though just not as much as you would gain from a tune.
Exhaust is a most defiantly a must though.

Yes its going to throw codes when you open it up. I don't know how to get rid of or trick it so the codes don't get thrown. You will have to search on here more and the solstice forum. Someone has had to figured it out by now.
Where I come from with the SRT-4s we have a few tricks for stage 0 or any of the Stage1+ PCMs don't throw the code becauase I guess MOPAR expected you to upgrade your exhaust(and sold exhaust)

To be honest I don't own a sky or solstice. I just came on this forum reading up because my father has been interested in a Solstice GXP. So I was just looking around seeing what is popular on the boards and getting a sense of what kind of knowledge is on the boards compared to the SRT-4 forums where there is an abundence of knowledge and information. I registed just to send a PM to someone but I figured Id help a little since your post didn't have any replies to your questions and I knew the answers.(well except the code problem)

nick112207 · 07-19-2008, 10:27 PM

well thanks for you answer. I too dont exactly own one (yet) but i'm working on getting one. I'll have to just look at the stock exhaust setup and see what i want to do.

On a side note i think it was on this forum or the Solstice side but i was doing a search and someone said something about having a catless downpipe and how it will cause the engine to throw a code but it doesnt do anything to the performance. Idk if thats true and its just essentially making you know your Cat isnt working. I know when i had my ranger you had to be careful because depending on what the O2 sensor read it would make your engine run leaner or richer but idk if it does that to the Sky/Solstice

Yeah it shouldn't matter but I'm not 100% sure...If that holds true it won't affect performance but the light will always be on and you will fail to know if any other problems arise because the light will be on. So its better to find out how to get it to stay off. If you reset your PCM(disconnect battery for like 5min) the code will go away until you open the cut out again. That would be annoying though so most defiantly keep looking for the answer on the way around it.

nick112207 · 07-20-2008, 07:59 AM

i thought there was one guy on the GXP side of things who they said had a cutout right after the turbo. I think he said when it was open it sounded like a small personal aircraft taking off haha. i'll have to see if i can find that again and ask the guy how he got past the O2 sensors throwing a code
