ZZP 2.5 inch Stainless Cobalt/Ion Downpipe

SKU: ZZ-E25DP-A-400-BP

$219.99 Sale price

Transmission
Regular price $219.99

This fits on all Cobalt/Ion/G5/HHR/Pursuit models with the 2.0L supercharged, 2.2, & 2.4L naturally aspirated cars. Will not fit '08+ turbocharged models.

Includes:

    • Stainless flex

    • Stainless flanges

    • Stainless Spun metal cat 

    • Stainless piping

Our downpipes are made from stainless steel. No worries about rusting or paint flaking off. It costs a little more but we feel it's worth it. All welding is done to the strictest of standards and bears a professional finish. Weld quality is higher than any other downpipe manufacture. We promise our welds to be 100% leak free. Even the flanges are stainless, which isn't something most companies can say. When shopping around, ask if the downpipe is 100% stainless, ask for a close up picture of their weld. You'll know right away, what true quality is and what it isn't.

The stock pipe narrows down to a 2" hole before flowing into the cat. This is very restrictive causing KR and a loss of HP. Our 2.5" stainless bolt in downpipe remove all of the stock downpipe restrictions. No more 2" inlet, no more O2 bung dimple. By doing so gains of over 15HP can be had along with a substantial drop in KR. Most users can drop a pulley size after adding our downpipe. Plus our 2.5" bolt in mates to the stock or 2.5" cat back exhaust system without any welding.
Transmission: This determines if you need a downpipe for an automatic or manual transmission.

Excellent quality

No problem installing this as well as the shorty header, and most importantly no check engine light! Went 2.5 and it sounds great, better than having different diameters like the stock junk. Always a great experience purchasing from ZZP!
