Hey Fellow Supra Drivers..I'm in the market for a downpipe for my 88 supra turbo and I've been looking at various makes from generic brands to HKS. Which downpipes would be most recommended?? I was aiming more towards buying the HKS because HKS offers 75m pipe size but if one of those generic knock-off brand works as well as the HKS one, I would rather spend less for the same amount of performance. Let me know what you think..advices and tips would be GREAT!! Thanks a Bunch!!
