New Exhaust System

That’s what mine did. Cut the mid pipe, placed cat, weld.

 

Did they bother welding in a flange?

 

No and I didn’t ask them to. Mid pipe still connects like factory. They just cut out a section and welded them in.

 

we need more sound clips of everyones setup

 

Did your cats have flanges on them?

 

Nope. https://performance-curve.com/2-5-f...verter-high-flow-stainless-metallic-200-cell/ The previous owner had cut the secondary cats out and welded in some pipe so I just had him cut a section out and install the cats. Do the factory secondary cats have flanges on them?

 

I believe so because the ARH cats are flanged

 

appreciate the replies. I messaged them around lunch time today to ask if they would consider another gb soon before I make my purchase. Haven't heard back but hoping they reply.

 

used “Tundranation” code they had posted on their IG page, code worked for me & saved some money & exhaust has been pretty badass, wanting to add the High flow Downpipes now.. lol

 

Just did a 180 mile round trip towing the rzr. S5 doing 70mph. It can still get loud under load but it’s manageable. Still got 9.2mpg which is normal.

more sound

 

Exhaust sounds good, but I tuned it out and just listened to your bypasses…. Clickity click click click!

 

Haha so much clickity clicking

 

i like the growl it gives

 

you running high flow cats too?
headers stock or..?

 

the downpipes from spd are high flow primaries and deletes the secondary’s

 

Stock headers

 

I’ve put enough miles on this (800 miles) to say I’ve got zero complaints with it. Sounds good. Wife says it sounds good. Tows fine. Drives around town fine. Highway mileage increased but city and towing stayed the same. I’ve noticed no torque loss, no having to push the pedal harder to accelerate, no issue of 6th gear being usable. I am running 5.29’s and a tune but also 34” tires with front and rear bumpers. My exhaust shop that did the cats was really impressed with the craftsmanship and design and he’s an engineer by trade. Props to @reywcms for working on the development of this. Solid system.

 

Yes!

 

Definitely sounds better than my old setup..

I received my spd cat-back system yesterday and installed it last night. I'm coming from a flowmaster outlaw exhaust, and this is both quieter and less drony at the 1700-2000 RPM range which is exactly what I was after. Installation was straight-forward -- this being my first cat-back install I'll offer some suggestions, but likely some more practiced folks will have corrections. It took about 30 minutes to put in once the old system was out (also about 30 minutes to remove).

0. I live in FL, so rust wasn't much of an issue.
1. Soak the bolts in penetrating oil a couple hours before you start. Put the back end on ramps.
2. Unbolt and remove the old system. Helps to spray the rubber hangers with silicone lubricant so they slide off easier and are more pliable.
3. Completely remove the rubber from the front two hangers (for the pipes). Replace with 2 inch worm clamps, fully open (or something similar...just need some temporary support for next steps)
4. Fit together the exhaust on the floor on the passenger side of vehicle. Place your clamps on the two inlet pipes oriented as you'll want them, but loose.
5. Slide the exhaust under the vehicle and over the rear axle. Poke the rear hanger into the rubber. Seat the muffler hanger into the rubber. Use the worm clamps to hold the pipes near position. Then go back and fully seat the rear and muffler hangers.
6. Attach the exhaust connections. I removed the gasket from the vehicle side of the pipe and the SPD provided gasket fit well. The flanges fully touched once tightened, but I left them loose at this stage. Just get the bolts started.
7. Fully seat the pipes into the muffler and clamp. I used a ratchet strap to ensure mine were fully seated, but it wasn't necessary -- just a good way to check. Lift the muffler about an inch (knee worked for me) and tighten the clamps connecting the pipes to the muffler.
8. Fully tighten the front pipe connections. They should sit flush together.
9. Install the two rubber hangers on the pipes (remove the temporary hose clamps holding them up from step 5).
10. Remove the bubble wrap from your muffler, put away your tools, and go for a test drive. Try not to smile too hard.

 

Just ordered the cat-back versions (tundranation coupon code worked for 5% off). Looking forward to it! coming from a dd trd replacement 5x12 versions. Excited after watching all the videos in this thread. I am sure I'll be swayed and order the downpipes later this year lol but just wanted to start with the cat back.

 

Omg why did I open this thread!?!

I want those hi flow cat down pipes and the cat back system. Wonder how much I can sell my TRD exhaust system for….

 

Your TRD should sell quick for sure

 

Well said screw it and just ordered the downpipes too lol why not.

 

hahah there ya go, buy once, cry once.

money is tight for me so I’m gonna have to hold out till Black Friday and hope they have a sale

 

bunch of moneybags in these forums

 

Nah, we’re just not financially responsible!

All I can say is if I tip over dead, please come get all my fishing gear before my wife sells it for what I told her it cost…

 

lol i dont even have the responsibill finances to be financially responsible
