Custom exhaust parts

I'm thinking of putting together my own custom exhaust for my 06 vibe but need to know all the components I need from the resonator to the tip.

You'll need the flange for where the exhaust bolts together behind the resonator over the rear axle, and then a muffler that will fit under there.

I recently replaced my resonator with a Thrush glasspack (24205) and it cut down on the drone a bit. The paint is already almost gone :lol: so it's going to look "stock"-ish soon.

I've been really wishing I could weld so I could do some experimenting with the piping. There's supposed to be an ideal length for the header and the exhaust for good sounds, and I also saw on a show where they customized a Camaro with an LS; they reversed the position of the muffler and then looped pipe to go the correct direction through it, so that the pipe would be longer and change the sound.

Here's some more info:
You need the pipe not to be restrictive, so not too narrow, but if it is too wide, the exhaust gases will cool and move slowly out rather than staying hot and creating that vacuum to speed it through the system.

I was doing some research on how to tune sound, but apparently neglected to save the info I found because I am stupid.

The last thing is: You can't make your exhaust sound like anything but a 4-cylinder. It will never sound like a flatplane V10 or V12, but you can still tune the sound not to sound like an explosion of monkey-farts, or maybe Jeff Goldblum's weird Jurassic Park laugh.

What is the pipe that connects to the flange piece that goes to the muffler?

What do you mean? Material?

The actual part. The intermediate pipe I believe

Not really sure, because I just go to an exhaust shop, point, and have him weld stuff in and fabricate as they need to.

if you dont mind me asking how much did that cost you in the end?

My favorite guy charges $20 per weld. The rear Thrush muffler, DC Sports tip, and welds were $32, $20, and then $60 (some pipe had to be fabricated). I initially had a Magnaflow setup but the internals of the muffler broke free within 24 hours, and some people experienced having the replacement mufflers of the same part number failing over and over. I can't afford to have labor done numerous times.

The Thrush glasspack was $23 and $40 or $45 to weld in.

Not bad! :D

I built a custom exhaust for my '09 1.8L. I used a Moroso stainless steel bullet style muffler for a resonator. I went with a Flowmaster series 50 muffer with a Borla intercooled tip. The 2.25" straight and J-U bends S.S pipe came from Yonaka Motorsport. On the '09 the stock resonator is welded directly to the 2nd cat. Cutting the exhaust between the cat and resonator the outlet diameter is 2". The inlet of the Moroso is 2.5" so I had to form reducers for both the inlet and outlet from S.S sheetmetal and remanufactured the muffler. I MIG tacked it all together then had a friend with better eyes finished all the welds with a TIG.

If you decide to use any Magnaflow parts for your exhaust, I highly recommend ordering from Hott Exhaust. They have the cheapest prices on Magnaflow parts and shipping is free. Be sure to click the link on their homepage that says "Get Coupons". Tell them what part/s you're wanting and they'll send you a discount code to use. I ended up paying right around $440.00 shipped for the Magnaflow catback exhaust system for my Vibe last July. The discount code they sent me saved me around $150.00.

I'm definitely going to get the parts together to have it custom made. I can get the walker resonator pipe to save me the trouble but need to know what piping I may need after the resonator all the way down through the muffler and to the tip.

I just thought I'd say the Thrush glasspack ended up having a detached core and rattling after the fiberglass went out. I knew the fiberglass packing would end up cooked, but didn't expect the core to start rattling. Probably going to have my coworker replace it with a straight pipe until I can get a new resonator or muffler for that spot. If I could weld, I'd experiment around, but alas, I am a mere apprentice mechanic. I was thinking of drilling holes and driving screws into the muffler to see if they could support the core, but I don't think I'm going to try that just yet.
