Re: aftermarket muffler

SmokeyWren:

I have a 3.5" Walker BTM and like it a lot. However, was wondering if you suggest installing a 3.5" downpipe with it too? I have been considering a full 4" system...but it's posts like yours that make me hesitate because I don't want to waste the money. I don't even have my programmer installed currently, but will be replacing it with SOMETHING like a 10K mod at a minimum.

Do you recommend getting the 3.5" downpipe with the Walker BTM over the 3" that comes from the factory?

Re: aftermarket muffler

I'd definitely upgrade from the stock 3" to the 3.5" as it'll lower your EGT's some but SOTP results may not change.

Check out ITP's explanation on downpipe upgrades.

Re: aftermarket muffler

Well, it looks like the 3.5" pipe is $120 plus shipping. If I can get a full 4" system for $300 (Summit, etc.) then it makes me wonder if I want to mess with the 3.5" downpipe. The question is, can this be put on without welding, etc.? If not, then I have to pay $$$ for installation too.

Hard to decide. Although $180 savings buys a couple more mods!

If it were my money, I'd probably just install the Walker BTM and nothing else. The better downpipe will make a little difference, but very little on a '99-up. It's sorta like synthetic motor oil - it's better but not cost effective. [img]/ubbthreads/images/graemlins/cool.gif[/img]

Re: aftermarket muffler

Dennis at ITP(TDS Sponsor) also sells the Magnaflow mufflers used in the systems individually <font color="blue">HERE</font> . They are more money than the BTM, but you can get them in Stainless Steel which the factory piping is stainless although its not shiny.This keeps the system all stainless if you care about that and the Magnaflow is available in different lengths, I'm guessing the longer the quieter.

Re: aftermarket muffler

See my post above.Don't know if there is any performance difference between a Manaflow or BTM, but gives you another 4" option any how.

Re: aftermarket muffler

Thanks for the tips, what about the catalytic converter on my early 99? Would you recommend cutting it out? Does it restrict airflow like the stock muffler? My part of the state doesn't require emission testing.

No. It's illegal to mess with the emissions control system.

No, not unless it gets plugged up with soot. But it's designed to burn up the soot, so that shouldn't be a problem. But if the catalytic converter somehow gets plugged up, the fix is to replace it with a new one.

Your part of the state is covered by the Federal law which says it's a federal offense to alter the emissions control system on your vehicle. Last I heard, it was a $10,000 Federal fine plus a huge state fine if you get caught. Most of the voters in Colorado live on the eastern slope, and they have a big problem with the "brown cloud" over there. So the state fine is almost as bad as the Federal fine.
