Replacement downpipe?

[Archive]

I have the BAnks Stinger exhaust system on my early '91, and their intercooler - still all-stock turbo.

Is there any gain available from a different downpipe on a setup like mine? I'm not aware of any on the market, and when I asked Banks about it when I bought my system from them, they claimed no advantage would be gained over the stock one the truck came with?

It sure SEEMS that with all the effort made to reduce restrictions from the muffler on back, that SIMILAR attention to the downpipe would be worthwile as well - it LOOKS pretty restricted in several places...

My downpipe has a fat dimple right next to the bellhousing...
I called all the muffler and exhaust shops here in town today, not a one could get me
a complete 4" for my application, and only one shop in town could bend me a 4" cat-back... and the price went up $200 since the last time i checked... $350~>$550...
Think im gonna call Jardine
