cat delete

I got one last fall from 1320 via ebay. Installed couple weeks ago.

My wife and butt dyno says it was worth it. Rear spins easier. Not sure about mpg, right foot seems heavier now.

I have my CAT on the bench as we speak. I got the 1320 off Ebay, they had a buy it now or make offer. Can't exactly remember, but I gave around $125 shipped on the offer that they accepted. Springs are a pain, didn't get it back together yet. Likely won't have it out for a test drive for awhile as we've gotten snow and wintry mix again and the salt is back on the roads.

If with a top and a taller windshield you can get fumes into the cab. I just recently did the delete and added a plus 5 F4. I will be going back the the stick W/S.

Well worth the money, the cat delete and the Alpha CAI, more power and got me 4 mpg more. Just about any exhaust system will give you fumes with a tall wind screen.

I didn't have a lot of issues with fumes with the 2.5 welter stealth and the tall windscreen. Then I did away with the 90* pipe that turned it out to the side and replaced it with about a 30* pipe that put it out beside the wheel. That combo worked fine until I put the top on. Then I had plenty exhaust in the cockpit! I installed a wind restrictor on the front side of the hoops. That helped some but there was still too much noise and fumes. I have since re-installed the 90* pipe and now the noise and fumes are acceptable again. Now if I could just get busy and install some sun visors to stop the whistling all would be great.

Does this qualify as a cat delete?

Definite improvement. You can always punch it out yourself, back in 2015 that was about the only option available and many did it. Get the CAI also and you'll have free-er flowing in and out.

F4 was offering a modified Goldwing vent to allow some airflow through the windshield. That may help eliminate exhaust being drawn back into the cockpit.

is it worth it to get a cat delete pipe? Other than sounding a bit better would there actually be any noticeable difference in performance? It seems very over priced for what it is especially considering the fact I could get a DDM works CAI for about the same money.

Hi @edwardaneal a cat delete combo with a performance exhaust and a tune is absolutely the most performance gain available on a normally aspirated 2.4 Many reputable shops AND EXPERIENCED BUILDERS, have verified this on dyno runs time and time again, A header and a CAI are great for the egos, as they look amazing under the hood, but the stock Gm exhaust manifold is one of the best designed exhaust manifolds on any stock engine and provides no noticeable restriction whatsoever when dealing with the normally aspirated gas flows, and same goes true for the Polaris intake. they provide adequate flow for the volumetrically limited flows a normally aspirated 2.4 can injest and exhaust. But dont take my word for it ! Read the many great posts on this exact same claim by some of the Industries most experienced 2.4 builders such as Dave at DDMWorks.

I looked at my eBay. I offered $135 for one like this from the same seller, and paid the $15 shipping. So it was $150. This is the 1320, and it's a buy it now or best offer. I offered $150 shipped I believe, and that's how the sale broke down on eBay.

Thanks @kev

I just picked one up for S140 shipped.

I have a 1320 exhaust and did it more for the heat than performance. It noticeably does both.

I have decided that I want to go more the stereo route and want to quiet it down but keep the heat down.

I already have the manifold cover and picked up a factory heat shield.

I picked up a cat delete also. Works awesome! Haven't seen one since.
