I'm saving up to relace my entire exaust system and was just wondering what would be the best setup.

As of now I'm thinking of getting the RPW 4G15 extractors (will these fit my Excel?) Then running 2 1/4 inch mendrel tubing to a performance muff. (not sure which one, but I heard your wife had a nice one.<img src=/images/forums/snitz/smile.gif width=15 height=15 border=0>) Any suggestions on a muffler or any other part of the setup?

So I take it no ones ever used the RPW headers or put a 2.25" exhaust on the 91 Excel 4g15?

As for your exhaust piping diameter...I would suggest you keep it to 2" instead of 2 1/4". You'll probably retain and/or produce more power through your rpms with that setup. If it's anything like an Accent, it's quite a jump from a 1.5 or 1.75" diameter pipe.

I was at Midas today and they said that a 2 1/4 probably wouldn't fit over the axle. They also said I would need a turbo exhaust beacause I would need more backpressure, is this true? Would a normal performance exhaust be fine with a 2"? What's a good price for a performace exhaust? Midas said for a turbo exhaust it would be between 500-600 Cdn. I need this done soon because y stock pipe is falling apart.

There is ways to maximize pipe size and keep back pressure to a certain extent. As far as a turbo exhaust I believe that requires a minimum of 3" pipe. I also have read and heard from performance guys that a 2 1/4" pipe is the size you would need for a 1.5 liter engine. I haven't done exhaust on my car but I did do a muffler which got rid of some of the backpressure with the stock muffler. I bought a straight through style muffler by Magnaflow. There are other brands that are straight through and don't have inner cores that add backpressure. it all depends on your application. As for the RPW Headers I've heard from peeps in australia that they are a good investment and a 2 1/4 pipe would be ideal. As far as mufflers I'd run by a performance shop because midas doesn't specialize in performance exhausts.

Thanks for replying but I already got the work done. I went with 2" cat back for now and a Magnaflow straight through muffler. I'll probably be getting the RPW headers within the month, where's the cheapest spot to get them in the US or even better Canada? So far the new system has added quite a bit of tourque, but not a significant amount or high end. Hopefully the headers will help boost both of these up some more.

Murray, how does your exhaust sound? As I have a 92 Excel and have a 2" catback, but no performance muffler, but I am looking for one that will be good for what I want.

Thanks! <img src=/images/forums/snitz/thumbup.gif width=25 height=18 border=0>

I have one of the round Magnaflow XL Turbo mufflers. Looking on there site they don't list them for cars, but that's what it said on the box. It pretty much sounds the same as the factory exhaust, only a little deeper and a little louder. I wasn't going for sound when I bought it though. I'd say it's given me a good 5-8 horses.

While we wre still on the convo on exhaust, i own a 86 excel and i went to 2 1/4 all the way back to a magnaflow exhaust and its just not cutting it i lost all back pressure it sounds alright but i would rather have the performance than the sound. It has the shitty 1.6 motor any suggestions?<img src=/images/forums/snitz/mad.gif width=16 height=16 border=0>

I think the easiest fix is to bya new muffler. One of those with little metal extrusions in the inside of the airflow of the pipe, what it will do is create back pressure. Thats what I think would help. But I'd ask a performance shop that does exhaust that you want to keep the piping but add more back pressure.

Thanks ill do that but is there any other mods that i could get my hands on? I have the rims, the exhaust, but the 1.6 carberated engine just aint cutting it, it has 144k miles on it i know its not good, but i removed the air filter and that helps the exhaust note but will probally end up damgeing the engine but its only temporary and i am in the process of expeirmenting.Also if this helps anyone else the euro tails off of a 92-93 accord will fit with minor modifications on my 86 hyundai Excel. Anyone with suggestions on beefing u the engine with some mods please let me know..<img src=/images/forums/snitz/moon.gif width=15 height=15 border=0>
