And if i was to weld in a 1-2ft pipe between where the cat should be what wouldI do with the oxegen sensor? Nothing just let it be?

 

im assuming that if u take off ur cat then you dont need the o2 sensor anymore... but im telling you, do NOT remove the cat, it will sound TERRIBLE!!

 

You wont need the sensor.. but you should still bolt it up. You can just put it in the same place as the stock.

That looks like an ebay exhaust.......

 

Yeah its a ebay exhaust. Costs about $200.

And what is a resinator???

And by sounding bad what sounds bad about it? Dont cars get a deaper tone when you remove the cat?

 

not with ur 420... i took off the resonator on my rs, and between 3-5K rpm's it got really "whiny", or farty as some would say. it sounded awful! real high pitched an nasty... thats just the curse of those cars. the resonator on ur 420a will actually be the thing the gives it a deeper tone, so please please please trust me when i say keep the resonator, and keep the cat! you'll thank me when you do

 

And you say nothing about the ebay exhaust?

eBay is NOT a performance parts store. 99% of the stuff on there is absolute ****, including that exhaust.

 

Called a catback. Not really looking for performancejust want it to be louder.

 

sorry, i meant to mention it and i forgot... and notice the name "catback"... meaning the exhaust is from the cat... back lol... but NO ebay stuff either... its not good at all... just by trying to save money now you will regret it later

 

So Will any aftermarket cat hook up to te hheader and rest of the exhaust?

And how fat is the stock exhaust piping on a 420a?

 

it's 2.25in... they're made to bolt up to ur cat, not ur header
