Exhaust
 
I've got the 2.5 engine. I have inspection coming up, and I'm almost 100% sure I'll fail on emissions and have to get a new cat. I can hear it rattling when I drive and on start up, and it barely passed 2 years ago. I've seen people talk about high flow stuff to help this engine some with power. Are any worth it? Any recommendations? Also, the exhaust will need replacing too, any recommendations there? Thanks.

Check out Quadratec for a High-flow cat and a performance cat-back exhaust. You should find good prices.

Im lookin to beef up my 4.2 think the glasspack would work or maybe go cherry bomb?

I have seen online for
around 75 for cat converter
Cheap I think

Yeah - a cat from advance or napa isn't that expensive, and neither is the exhaust, but if I'm going to have to replace - is the performance stuff really going to help at all? And if it does help - is it worth the extra money spent?

it will sound better, but you will not gain any HP

I put a glass pack on my 2.5 with a new cat and it gave the little 4 banger some life

take off your cat. cut a hole on the top of it take everything out and weld it back up. There you go a High flow cat.

That's funny I like that High Flow Cat, but i don't think that it will sound the greatest. LOL
