a few ca guys have cut the hole to a 3 inch hole in and out on the factory cat, then welding the headers 3 inch down pipe to the factory cat.
or you need to find tog, or slp headers, both are carb compliant.

Want more flow.. Get rid of the plog/Dp and go with a set of headers. With your current setup there's no way your out flowing what you currently have.Quote:

Only reason I went with 3" over 2.5" is because I got a hell of a deal on the piping and was way cheaper then what the 2.5 piping was selling for.

yeah those headers arent friendly on my wallet.Quote:

YouTube. There a bunch of 3800 guys that run the XS I'm sure you'll find a few videos to compare

Thats what im doing. Not much on the xr1s not to mention my question is so specific.Quote:

So, I found a cheap solution: buy brand new resonator the right width from a member here for a good price, bought a complete '07 exhaust off of Craigslist with 40k on it for $35, sell cat off of that. Total investment around $35.
And I just loath that raspy sound when under acceleration then backing off, anythign to avoid/keep that to a minimum I told myself.
Personally, unless your pushing a metric-ton of power the 2.5" exhaust seems to be just fine. (from what I've read) And unless it's turbo'd and/or cammed then spending anything extra on exhaust on a GP just seemed pointless to me, like spending 1k to try and sound like a V8 as some people do. The only essential thing seems to be getting rid of the restrictive U-bend on the 6th gens. I'd rather spend the money on power mods than exhaust, if I was trying to spend money on this old thing, lol.
Just my $0.02, from what I've heard(literally, lol)/read. I'm still a noobie though, so pardon me if I got anything mixed up.
Yup because 99% go with what's been proving to sound pretty damn good. That's why XS pro come up so much.Quote:

And yes the longer the resonator the better. Kills drone especially that god awful drone you tend to get during deaccleration. It'll never sound like a v8 so don't try to even it to sound like that.

Is the resonator worth having like how much does it fix? I just figured it would restrict the flow so why bother same with the cat.Quote:

No it's a straight through design, it won't restrict flow. These cars sound like ass without a resonatorQuote:

Have you ever seen the inside of a resonator?Quote:

After installing my Borla XS's (PO removed resonator), I went about two weeks before the drone made me pull out my hair. No resonator makes a HUGE difference.
I believe the XR-1 is more of a racing muffler, and is louder than the pro-XS. My favorite sounding set up on a 3800 is a glasspack in place of a resonator, and
two borla pro-xs mufflers at the rear. It's not raspy at all, and the glasspack gives it a bit of a unique sound too it.
It's a 3800.
It's always crappy sounding.
You can try and mask it all you want.
Big resonator, catless headers, and a quiet set of mufflers and larger diameter piping that probably isn't needed is going to net the best exhaust note without a turbo.
What's the best stainless resonator to use? Does it matter where you put it?
