Exhaust problems

[johnnyreble]

Spent last week or so Dyno tuning my supercharged NA, max we could get was 140rwhp which we knew was off the mark, we decided that there was a restriction somewhere so took off the cat back system and immediately got an extra 40 hp, so am now getting a muffler made for it so I can track it this weekend and will retune it next week

moral of the story ... don't buy cheap catback off ebay .. mine had only done 10,000 ks and was all blocked up. we haven't pulled it apart yet to see what's going on with it .. anyone else had this problem ?

Massive difference! Glad you've found those lost killerwasps. What headers are you running?

I'm running a stock exhaust on my turbo and it's pretty slow haha. Just a temp measure to get the car driving until I finish making my new one so I'll reply when I change.

running cheap ebay headers ... I'm a slow learner .. but she's noisy now, just gotta get it retuned

I bought the FFS kit with a MP62 supercharger

Just to chime in as I've done my exhaust. It made an absolutely massive difference on my turbo over stock. Night and day.
